initialize, tools/list and the jpverify_guide tool are free, so you can inspect every tool and its input schema before paying for anything.

Tools

Tool	Price (USDC)	What it does
`jpverify_guide`	free	Tool catalog, prices, example inputs; recommends a tool for a question
`jp_entity_resolve`	$0.25	Identify a Japanese company from an English, brand or romanized name (with an English address, postal code or prefecture), a website or e-mail domain, T-number, corporate number, LEI or securities code; returns the legally binding Japanese name, kana, English name with its source, status and qualified-invoice registration, in English.
`jp_invoice_issuer_match_extract`	$0.10	Read a Japanese invoice (text, HTTPS file URL, or small Base64), then match its issuer to the supplier's expected T-number or corporate number, and judge input-tax-credit eligibility.
`jp_supplier_resolve`	$0.10	One coverage-aware supplier check combining company, qualified-invoice and address evidence.
`jp_invoice_extract_and_verify`	$0.10	OCR a Japanese billing invoice, validate it locally, resolve the issuer against NTA registries, and judge input-tax-credit eligibility (eligible / not_eligible / needs_review).
`jp_invoice_issuer_match`	$0.05	Match an invoice issuer (structured fields) to the supplier's expected T-number or corporate number from your master data; invoice, expected and registry values stay separate.
`jp_business_card_extract`	$0.03 (default) / $0.10 (enrich)	Read a Japanese business card (front/back HTTPS image URL or small Base64); enrich=true adds a registry pre-check of the organization.
`jp_invoice_issuer_check`	$0.03	Verify a T-number and compare the issuer name and address with Japan's NTA registries.
`jp_receipt_extract`	$0.03	OCR a Japanese receipt with local amount, tax and T-number checks; detected T-numbers are verified with the NTA registry.
`jp_invoice_extract`	$0.03	OCR a Japanese billing invoice (text, HTTPS file URL, or small Base64) with local date, tax, arithmetic and T-number checks; no registry lookup.
`jp_invoice_registration_verify`	$0.01	Verify a Japanese qualified-invoice registration number (T + 13 digits) against the NTA invoice registry.
`jp_company_verify`	$0.01	Verify a Japanese company by name, 13-digit corporate number (法人番号), or address against the NTA registry.
`jp_address_normalize`	$0.005	Normalize a Japanese address into a canonical hierarchy (prefecture to room) with the confirmed match level and an English rendering from Japan Post romanized data.
`jp_address_validate`	$0.005	Validate a Japanese address with parser, postal and geocoder evidence and return exact/partial/ambiguous/conflict/unverified.

All tools are read-only (readOnlyHint: true). Registry results are a public-data pre-check, not KYB, AML, sanctions screening, or legal or tax advice.

How payment works

Call a paid tool without payment. The result is an x402 PaymentRequired object (isError: true, structuredContent.accepts[] with the exact USDC amount, payTo and network).
Sign the payment with an x402 client and call the same tool again with the payload in params._meta["x402/payment"].
The tool runs; payment is settled only after a successful result. The settlement receipt is returned in _meta["x402/payment-response"].

Invalid input is rejected before any payment is requested, and failed calls are not charged. MCP clients without an x402 wallet can still use jpverify_guide and the HTTP API documentation.

Example tool call:

{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"jp_invoice_registration_verify","arguments":{"registration_number":"T1013301046627"}}}

Other entry points

A2A agent (v0.3): AgentCard https://api.jpverify.com/.well-known/agent-card.json, JSON-RPC https://api.jpverify.com/a2a (message/send, tasks/get), payments via the a2a-x402 extension
HTTP API: OpenAPI https://api.jpverify.com/openapi.json, x402 catalog https://api.jpverify.com/.well-known/x402.json, agent guide https://api.jpverify.com/skill.md
Batch verification, async batch jobs, JP PINT validation, FSA regulated-entity checks and EDINET filings are available over the HTTP API only.

Complementary checks

JPVerify confirms who a Japanese counterparty is (corporate number, T-number, address). It does not screen sanctions lists. If your onboarding flow also needs sanctions screening, run it as a separate step on the resolved name:

Use the official English or romanized name from the corporate-number record (jp_entity_resolve returns it in name_en, with its source). Most sanctions lists are matched on Latin-script names and aliases, so Japanese script often finds nothing even when an entry exists.
Check official sources such as OFAC Sanctions List Search, or a screening tool. One that runs on the same x402 rail (USDC on Base) is AgentReader's /sanctions-batch, which checks OFAC, UK, UN and EU lists and has a free preview.

Third-party services are listed for convenience only. JPVerify is not affiliated with them and does not endorse or verify their results. Confirm any potential match with the issuing authority.

制裁リスト審査が必要な場合は、法人番号データの英語表記またはローマ字表記の名称を使い、別の手順として実施してください（多くの制裁リストはラテン文字の名称で照合されます）。審査先の例は英語版の Complementary checks を参照してください。第三者サービスは参考として掲載しており、JPVerifyとの提携や推奨を意味するものではありません。
