Pricewatcha API

The Pricewatcha API is the Structured Product Price Intelligence Platform for developers, automation and AI Agents.

The Pricewatcha API derives from the pricewatcha.com application. It provides price tracking, alerts and product intelligence beyond the Pricewatcha dashboard. This repository documents the public HTTP API, OpenAPI schema, official SDKs, MCP server and examples. It does not contain the production web application or scrapers.

Status: Available · Version: v1 · Base URL: https://pricewatcha.com/api/v1

Interactive API keys (browser): Developer page


Optional: verify connectivity with GET https://pricewatcha.com/api/v1/health. Then pick one of the three paths below.

Quickstart

Path 1: Browse prices (no auth)

Use demo product IDs from the demo catalog or search the catalog:

curl -s "https://pricewatcha.com/api/v1/products/demo_iphone_15_pro"
curl -s "https://pricewatcha.com/api/v1/search?q=iphone+15&limit=10"

Search is case-insensitive token AND (all terms must appear; word order does not matter). Results include the full Pricewatcha catalog, not only URLs submitted via POST /track. Use product_id from search for product and price-history endpoints (prod_* or demo_*).

Path 2: Track a product and get price history
curl -s -X POST "https://pricewatcha.com/api/v1/track" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://www.backmarket.de/de-de/p/example-product"}'

curl -s "https://pricewatcha.com/api/v1/products/{productId}/price-history"

POST /track returns HTTP 200 with a bounded server-side long-poll (~25s). Use product_id from the response for price history. Optional: send Authorization: Bearer pwk_live_… for higher track, search and product-read quotas.

Fast shops return status: "completed" with the full product in one call. Slow shops return status: "running" with a job_id. Poll GET https://pricewatcha.com/api/v1/jobs/{jobId} until the job is completed or failed. More detail: Async track & poll.

Path 3: Price alert with webhook (API key required)

Create a key on the Developer page, then:

curl -s -X POST "https://pricewatcha.com/api/v1/alerts" \
  -H "Authorization: Bearer pwk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "product_id": "prod_a1b2c3d4e5",
    "notify_on_drop": true,
    "min_threshold_price": 500.00,
    "webhook_url": "https://your-n8n-instance.com/webhook/abc",
    "notify_email": true
  }'

For authentication and data boundaries, see Authentication and Data boundaries.


Authentication

No credential required for catalog search, product detail, price history and async track/poll. Without a key those endpoints use anonymous rate limits. Send an API key to use the higher per-account track, search and product-read quotas.

Protected API v1 endpoints (alerts, webhooks, authenticated track callbacks) use:

Authorization: Bearer pwk_live_…
CredentialFormatWhen to use
API keypwk_live_…Recommended for scripts, agents, n8n and server integrations. Create on the Developer page.
Login session tokenJWT from POST https://pricewatcha.com/api/auth/loginWebsite UI and headless key bootstrap only

Do not use the login session token for alerts, webhooks or other API v1 calls once you have an API key.

See Access model for which routes are public vs authenticated.


API keys (browser)

Log in on the Developer page to create and manage API keys in your browser. The full secret is shown once at creation.

For agents without a browser, use headless key bootstrap below.

Using your key on protected endpoints:

curl -s -X POST "https://pricewatcha.com/api/v1/alerts" \
  -H "Authorization: Bearer pwk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"product_id": "prod_a1b2c3d4e5", "notify_on_drop": true}'

Headless key bootstrap (for agents)

If an agent must obtain API credentials without a browser, authenticate once with the same email and password as on the website, create an API key, then use pwk_live_… for all further calls. This is not a separate agent login: it is the normal Pricewatcha account login exposed as an HTTP endpoint.

How login via API works

POST https://pricewatcha.com/api/auth/login accepts JSON email and password and returns a short-lived access_token (login session token). The Developer page login modal calls the same endpoint; in a script or agent you call it directly with curl or your HTTP client.

  • You need an existing account (register on the site or via POST https://pricewatcha.com/api/auth/register).
  • The email must be verified: otherwise the API returns 403.
  • Wrong credentials return 401.
  • Use access_token only to create keys; for alerts and webhooks use the pwk_live_… key from step 2.

Step 1: Login

curl -s -X POST "https://pricewatcha.com/api/auth/login" \
  -H "Content-Type: application/json" \
  -d '{"email": "you@example.com", "password": "YOUR_PASSWORD"}'

Response (HTTP 200), AuthResponse:

  • access_token (string): login session token (JWT)
  • token_type (string): always "bearer"
  • user (object): id (string, UUID), email (string), email_verified (boolean)
{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "token_type": "bearer",
  "user": {
    "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
    "email": "you@example.com",
    "email_verified": true
  }
}

Send the token as Authorization: Bearer <access_token> in step 2. Session tokens expire; do not store them as the long-term credential for an agent.

Step 2: Create API key

curl -s -X POST "https://pricewatcha.com/api/keys" \
  -H "Authorization: Bearer ACCESS_TOKEN_FROM_STEP_1" \
  -H "Content-Type: application/json" \
  -d '{"name": "agent bootstrap"}'

Response (HTTP 200), CreateApiKeyResponse:

  • id (integer): key ID
  • name (string): label from the request
  • key_prefix (string): first 12 characters of the key (for display)
  • key (string): full secret; returned only on create, not on list
  • is_active (boolean)
  • created_at (string, ISO 8601 datetime)
  • last_used_at (string or null)
  • revoked_at (string or null)
{
  "id": 42,
  "name": "agent bootstrap",
  "key_prefix": "pwk_live_ab",
  "key": "pwk_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "is_active": true,
  "created_at": "2026-05-27T14:30:00.123456",
  "last_used_at": null,
  "revoked_at": null
}

Store key securely. Use it on alerts, webhooks and other protected API v1 endpoints, not the session token from step 1.

Health/health and /UnlimitedUnlimited

Send Authorization: Bearer pwk_live_… on POST /track, GET /search, or product reads to use the authenticated tier. Those endpoints remain available without a key at the anonymous limits.

Client identity: anonymous limits are keyed by client IP. Behind Cloudflare the API prefers CF-Connecting-IP over X-Forwarded-For so edge proxy IPs are not treated as distinct clients. The hosted MCP server forwards a stable X-Pricewatcha-Client-Id (OAuth token hash, else connecting-IP hash) with a shared proxy secret so MCP callers are not all bucketed under one egress IP. Authenticated track, search and product-read quotas are keyed by account (owner_id), not IP.

Monitor X-RateLimit-Remaining and honor 429 with exponential backoff. X-RateLimit-Policy names which window the headers refer to (track, track_hourly, track_daily, track_concurrent, job_read, search, search_hourly, search_daily, read, read_hourly, or read_daily).

Track quotas are counted from persisted jobs (api_track_jobs by client key or account), so they apply across multiple app instances. A long-poll that holds the HTTP connection for ~25s still counts as one track job when created — sequential tracks spaced farther apart than 60s will not trip the burst window, but hourly/daily and concurrent caps still apply.

Agents should prefer: start track → poll GET /jobs/{id} with backoff (not every 1–2s) → read product/history once complete. Retrying POST /track with the same URL while that job is still queued/processing reuses the existing job and does not consume another concurrent slot. Jobs left queued/processing longer than the scrape timeout (default 600s) are failed so slots cannot leak across deploys.

Search and product-read quotas are in-memory per app instance (not shared across Railway replicas the way track jobs are). Authenticated callers still get the higher per-account windows. Polling the same catalog queries on a short interval will still trip the hourly/daily search windows.

Exact numbers may change without notice (env overrides: API_V1_TRACK_*, API_V1_TRACK_AUTH_*, API_V1_JOB_READ_*, API_V1_READ_*, API_V1_READ_AUTH_*, API_V1_SEARCH_*, API_V1_SEARCH_AUTH_*).

Headers

When rate limiting is active, responses may include:

HeaderDescription
X-RateLimit-LimitMaximum requests in the window
X-RateLimit-RemainingRequests left in the window
X-RateLimit-ResetUnix timestamp when the window resets
X-RateLimit-PolicyWhich window the headers describe

HTTP 429

When limited, the API returns 429 Too Many Requests with a JSON body:

{
  "error": {
    "code": "rate_limited",
    "message": "Rate limit exceeded (track daily). Try again later.",
    "http_status": 429,
    "retry_recommended": true,
    "retry_after_seconds": 3600
  }
}

Agent guidance: honor 429, wait until retry_after_seconds / X-RateLimit-Reset, and reduce poll frequency on job status endpoints. Prefer spreading tracks over time rather than bursting near the hourly/daily caps. Anonymous 429 responses mention that an API key raises quotas.

Operators can receive an email when hourly/daily/concurrent track limits or hourly/daily search and product-read limits trip (cooldown per client; see API_V1_RATE_LIMIT_ALERT_*).

Abuse and IP restrictions

Sustained abuse of anonymous daily quotas (track, search, or product reads — for example exhausting the daily limit on several days from the same IP) may trigger an in-app restriction, not only 429.

  1. Notice (grace period). API calls still succeed. Responses include X-Pricewatcha-Restriction: notice and X-Pricewatcha-Restriction-Message with the pending-block warning. Rate limits still apply.
  2. Block. If there is no reply, the IP is blocked. Further calls return HTTP 403 with error.code access_restricted.

Email info@pricewatcha.com to discuss terms or restore access. Do not retry until access is restored. Retries will not lift the restriction.


Async track and poll

POST /api/v1/track submits a product URL and waits up to ~25 seconds (long-poll). No API key is required. Send Authorization: Bearer pwk_live_… to use higher per-account track quotas.

  • Fast shops: status: "completed" with full product in the same response
  • Slow shops: status: "running" + job_id: poll GET /api/v1/jobs/{jobId} until completed or failed
  • Repeat POST /track for the same URL while a job is in flight returns that job instead of starting another (and instead of a concurrent 429)

Jobs are retained for 72 hours. After expiry, GET /jobs/{jobId} returns 404: use GET /products/{productId} instead.

Typical flows

Fast shop (one call)
POST /api/v1/track → { "status": "completed", "product": { ... } }
Slow shop
POST /api/v1/track → { "status": "running", "job_id": "job_xxx", "hint": "..." }
GET  /api/v1/jobs/{jobId} → poll until terminal state
GET  /api/v1/products/{productId} and .../price-history

Track a product

curl -s -X POST "https://pricewatcha.com/api/v1/track" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://www.backmarket.de/de-de/p/example-product"}'

Response (200) when the scrape completes within the long-poll window:

{
  "job_id": "job_xxxxxxxx",
  "status": "completed",
  "product": {
    "product_id": "prod_xxxxxxxx",
    "name": "Example product",
    "shop": "Back Market",
    "current_price": 563,
    "currency": "EUR"
  },
  "error": null
}

Response (200) when still running after the long-poll timeout:

{
  "job_id": "job_xxxxxxxx",
  "status": "running",
  "product": null,
  "error": null,
  "hint": "Job still running. Call the get_job_status tool with this job_id to poll for the result."
}

Poll job status

curl -s "https://pricewatcha.com/api/v1/jobs/job_xxxxxxxx"
Completed response
{
  "job_id": "job_xxxxxxxx",
  "status": "completed",
  "product": {
    "product_id": "prod_xxxxxxxx",
    "name": "Example product",
    "shop": "Back Market",
    "current_price": 563,
    "currency": "EUR"
  }
}

Job states

StatusMeaning
queuedJob accepted, waiting to start
runningIngestion in progress
completedProduct intelligence in product
failedScrape failed: read structured error (HTTP 200 job lookup)

Recommended client flow

  1. POST /track with { "url": "..." }200
  2. If running or queued, poll GET /jobs/{jobId} every 2–5 seconds
  3. On completed, read product from the job or GET /products/{productId}
  4. On failed, surface error.code; backoff before retrying
Job lookup vs. scrape failure

When polling GET /jobs/{jobId}, interpret HTTP status and body together:

ResponseMeaningWhat to do
HTTP 404No job with this job_id (wrong ID or job expired after 72h)Stop polling; start a new POST /track if you still need the product
HTTP 200 with "status": "failed"Job exists, but scraping failedRead error.code in the JSON body (e.g. scrape_target_not_found)

A 404 is a lookup problem. A 200 with failed is a completed job whose scrape did not succeed.

Track job webhooks (push)

Authenticated clients can receive a push when a track job finishes: use callback_url (one-off) or webhook_id (existing subscription). Mutually exclusive. Callbacks do not consume extra quota beyond the authenticated track job.

curl -s -X POST "https://pricewatcha.com/api/v1/track" \
  -H "Authorization: Bearer pwk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://www.backmarket.de/de-de/p/example-product",
    "callback_url": "https://n8n.example.com/webhook/track-done"
  }'

With callback_url, the track response may include callback_secret (whsec_…) once: same signing as subscription webhooks.

When the job finishes, Pricewatcha sends a webhook with event type track_job_completed or track_job_failed (same payload shape as other webhooks). If you do not use push delivery, you can still wait on POST /track (long-poll) or poll GET /jobs/{jobId} until the job reaches a terminal state.

Note: Anonymous POST /track with callback_url or webhook_id returns 400 auth_required_for_callback. MCP tools use track → poll (no callback_url in v1).

SDK convenience

Official Python and TypeScript SDKs may provide track_and_wait() / trackAndWait(): a helper that calls POST /track, then polls GET /jobs/{jobId} until the job is completed or failed and returns the result. The HTTP API stays async-first; the helper only saves you from writing the poll loop yourself. See SDKs.

Deduplication

Repeated POST /track for the same URL may return completed quickly with existing intelligence.

Timeouts

Long-poll default is ~25 seconds. For slow shops, poll GET /jobs/{jobId} instead of extending the track timeout.


Search

Keyword search is case-insensitive. The query is split into tokens; a product matches when every token appears in the normalized product name, URL, platform/shop or related fields. Word order does not matter, and punctuation such as hyphens and slashes is treated as whitespace (Darth-Vader matches Darth Vader). Results cover the full Pricewatcha catalog, not only URLs submitted via POST /track.

Exact contiguous phrases still rank above other token matches when both match.

Endpoint

GET https://pricewatcha.com/api/v1/search?q=…&limit=…

Optional limit: default 50, maximum 200. Applied after exclude-term filtering.

Search is rate-limited separately from product reads. Anonymous callers get ~20 requests / 60s, ~60 / hour, ~200 / day; an API key raises that to ~40 / 60s, ~180 / hour, ~1000 / day per account. Honor HTTP 429 and X-RateLimit-Policy; see Rate limits.

q supports Google-style minus-prefixed exclude terms. q=iPhone+15+-cover+-case returns products matching both "iPhone" and "15" that do not contain "cover" or "case" in the searchable fields (case-insensitive). A lone - is ignored.

curl -s "https://pricewatcha.com/api/v1/search?q=iphone&limit=10"
curl -s "https://pricewatcha.com/api/v1/search?q=iPhone+15+-cover+-case"
curl -s "https://pricewatcha.com/api/v1/search?q=Darth+Vader+DX27"

Example response

[
  {
    "product_id": "demo_iphone_15_pro",
    "name": "Apple iPhone 15 Pro 128GB (Refurbished)",
    "shop": "Back Market",
    "product_url": "https://www.backmarket.de/de-de/p/example-iphone-15-pro",
    "current_price": 563,
    "currency": "EUR",
    "status": "active",
    "preview": true,
    "google_product_category_id": null,
    "google_product_category_name": null
  },
  {
    "product_id": "prod_a1b2c3d4e5",

    "currency": "EUR",
    "status": "active",
    "google_product_category_id": null,
    "google_product_category_name": null
  }
]

Use product_url for direct linking without an extra GET /products/{id} call.

Results always include google_product_category_id and google_product_category_name (null when unset). You do not need an extra query parameter.

Demo catalog (no scrape required)

Preview demo products are always available for integration testing:

curl -s "https://pricewatcha.com/api/v1/products/demo_iphone_15_pro"
curl -s "https://pricewatcha.com/api/v1/products/demo_iphone_15_pro/price-history"
curl -s "https://pricewatcha.com/api/v1/search?q=iphone+15+pro"

See the demo catalog on GitHub.


Data boundaries

Catalog price intelligence (current price, history, product metadata) is available without authentication. User-specific data (accounts, emails, alert settings, private watchlists) is never exposed through the public API.

Readable fields

  • product_id, name, shop/platform, product URL
  • Current price, currency, last checked, status
  • Price history, historical low/high, average, trend
  • data_source and data_source_label when price data comes directly from a merchant feed (merchant_feed"Direct merchant data")
  • google_product_category_id and google_product_category_name on product detail and search (null when unset). Search does not require an extra query parameter.
  • Demo entries may include "preview": true

Search, product detail and price history return the same fields whether the product was added via dashboard, API, MCP or demo data.

Product IDs

PrefixMeaning
demo_*Static preview samples (e.g. demo_iphone_15_pro)
prod_*Opaque stable ID per catalog product (one per URL entity)

Use product_id from search or a completed track job for GET /products/{productId} and .../price-history.

Webhook payloads

Deliveries include product-level event data only (prices, product IDs, event type), not user emails or account details. Verify authenticity with the subscription signing secret (whsec_...); see Webhooks.

Compliance

If you build on this API, disclose to your users that prices are informational and that merchant sites are authoritative.


Errors and error codes

Non-success responses use a structured error object. Inspect error.code: do not parse free-text message values.

Agent guidance

  • Branch on error.code, not message.
  • When retry_recommended is true, use exponential backoff and respect retry_after_seconds.
  • HTTP 200 on GET /jobs/{jobId} with status: "failed" is a job failure, not a transport error.

Full schemas: live GET https://pricewatcha.com/api/v1/openapi.json and the OpenAPI spec on GitHub.


Price Alert API

Create price alerts that send email notifications and/or fire webhooks when a price moves.

Each tracked product has one alert record per user. Combine any of:

  • notify_on_drop: notify on any price drop (no threshold required)
  • notify_on_rise: notify on any price increase (no threshold required)
  • min_threshold_price: notify when price drops to or below this value
  • max_threshold_price: notify when price rises to or above this value

At least one of those four settings is required.

All endpoints require an API key in Authorization: Bearer …. Full schemas: GET https://pricewatcha.com/api/v1/openapi.json (tag alerts).

Webhooks

Webhooks push signed HTTP POST requests when prices change, alert thresholds are crossed or authenticated track jobs complete.

Subscribe to event types globally or for a single product_id. Each event type is delivered as its own request.

ScopeBehaviour
Global (product_id omitted)Price events for products you track (watchlist) or for which you have an active price alert. Not the full catalog.
Scoped (product_id set)Price events for that product only.
Test (POST /webhooks/{id}/test)Sends a webhook_test payload to verify your endpoint; no product scope.

Catalog-wide price streaming is not supported. Use the test endpoint to verify delivery, then track products or create alerts for the events you care about.

Manage subscriptions via POST https://pricewatcha.com/api/v1/webhooks. Full schemas: GET https://pricewatcha.com/api/v1/openapi.json (tags webhooks, alerts).

Note: Target URLs must use HTTPS and must not resolve to private or internal IP ranges.

Signing and verification

Every delivery includes:

  • X-Pricewatcha-Event-Id
  • X-Pricewatcha-Event-Type
  • X-Pricewatcha-Timestamp (Unix seconds)
  • X-Pricewatcha-Signature (sha256=<hex>)

Signed string: "{timestamp}.{raw_body}" with HMAC-SHA256 and your webhook secret (whsec_…, shown once at subscription creation).

Warning: The webhook secret is shown only once. Store it securely: only secret_prefix is shown afterward.

Python
import hmac
import hashlib

def verify_pricewatcha_webhook(secret: str, timestamp: str, raw_body: bytes, signature: str) -> bool:
    expected = hmac.new(
        secret.encode("utf-8"),
        f"{timestamp}.{raw_body.decode('utf-8')}".encode("utf-8"),
        hashlib.sha256,
    ).hexdigest()
    return hmac.compare_digest(f"sha256={expected}", signature or "")
JavaScript (Node.js)
import crypto from "node:crypto";

function verifyPricewatchaWebhook(secret, timestamp, rawBody, signature) {
  const expected = crypto
    .createHmac("sha256", secret)
    .update(`${timestamp}.${rawBody}`)
    .digest("hex");
  const expectedHeader = `sha256=${expected}`;
  return crypto.timingSafeEqual(
    Buffer.from(expectedHeader),
    Buffer.from(signature || "")
  );
}

Delivery and retry

Failed deliveries retry up to 5 times: 1 min → 5 min → 30 min → 2 h → 12 h.

After 10 consecutive failures the subscription is auto-disabled.

AI Agents & MCP

Pricewatcha exposes a remote MCP endpoint: no local installation required. Connect your AI client with the URL below. Available tools include catalog reads (get_api_status, search_products, track_product, get_job_status, get_product, get_price_history) and price alerts (create_price_alert, list_price_alerts, get_price_alert, update_price_alert, delete_price_alert). Alert tools require a Pricewatcha API key and can notify on any drop or rise without a numeric threshold.

https://mcp.pricewatcha.com

For step-by-step setup, see Claude, ChatGPT, n8n and Make below.


Claude

What it enables: Ask Claude to search for products, track prices, check price history, set alerts and manage webhooks, all in natural language, directly in Claude.ai or the Claude desktop app.

How to connect: Claude.ai (web)

Step 1: Open the Customize panel
Click Customize (sliders icon) in the left sidebar of Claude.ai or go to claude.ai/settings/connectors.

Step 2: Add a custom connector
Under Connectors, click + to add a new connector.

Step 3: Enter the MCP server URL
Enter a name (e.g. “Pricewatcha”) and paste:

https://mcp.pricewatcha.com

Click Add.

Step 4: Done
Pricewatcha appears in your connector list with read-only tools (get_api_status, get_job_status, get_product, get_price_history, search_products, list_price_alerts, get_price_alert) and write tools (track_product, create_price_alert, update_price_alert, delete_price_alert). You can now use Pricewatcha in any Claude conversation.

Step 5: Configure tool permissions (optional)
Open the connector in your connector list (or return to claude.ai/settings/connectors) and expand Tool permissions.

For each tool — or for the whole Read-only / Write group — choose when Claude may call it:

SettingMeaning
Always allowClaude calls the tool without asking each time
Require approvalClaude asks before each call (default for new connectors)
Never allowTool is blocked

For everyday price checks and searches, set the read-only tools (or the whole read-only group) to Always allow. For track_product and alert tools, pick Always allow if you want friction-free writes, or keep Require approval if you prefer to confirm first. Alert tools need a Pricewatcha API key (pwk_live_...).

How to connect: Claude Desktop App

Same steps: CustomizeConnectorsAdd custom connector → paste https://mcp.pricewatcha.com. Tool permissions are configured the same way under Tool permissions in the connector settings.

Try:

  • “Find me a refurbished iPhone 15 Pro under €550”
  • “Track this product URL and show me the price history”
  • “Set an alert for this product when it drops below €500”
  • “Notify me whenever this product gets cheaper — no price target”

Note: track_product is a write tool because it creates a tracking job in the background. It does not modify or delete existing data. Alert tools (create_price_alert, update_price_alert, delete_price_alert) change your saved alerts and require an API key.


ChatGPT

What it enables: Search products, track prices, get price history, set price alerts and manage webhooks, directly in ChatGPT via MCP.

Prerequisite: Developer Mode (one-time)
Custom MCP connectors require Developer Mode: Settings → Advanced → enable Developer Mode. Available on Plus, Pro, Team, Business, Enterprise and Edu (not on the free plan). Pricewatcha tools only work while Developer Mode stays on.

Step 1: Go to Settings → Apps and click Add custom connector.

Step 2: Paste the MCP URL:

https://mcp.pricewatcha.com

Optional connector logo: PNG, max 10 KB. Download from https://pricewatcha.com/static/img/mcp/chatgpt-logo.png

Step 3: Authentication: Select OAuth. ChatGPT handles the flow; you may see a brief authorization prompt on first connect.

Step 4: Done. Example prompts:

  • “Search for a refurbished iPhone 15 Pro under €550”
  • “Track this product URL and show me the price history”
  • “Notify me whenever this product gets cheaper — no price target”

Warning: ChatGPT may show a DEV label on unverified third-party connectors. Pricewatcha only works while Developer Mode is enabled.


n8n

What it enables: Build automated price-monitoring workflows. Trigger actions when prices change or cross your alert threshold: no coding required.

Typical use case: When a tracked product drops below your threshold → send a Telegram, Slack or email notification with product name, shop, current price and alert name.
