Security Report

4.6
Use Caution4.6High Risk

Pulse402 is a pay-per-call x402 oracle whose Worker gateway forwards requests to one fixed canonical origin, with no shell execution, eval, hardcoded secrets, or data exfiltration visible in the provided code. The main concerns are low-severity: the free trial rate limit trusts a spoofable X-Forwarded-For header, and the SSRF guard is a simple substring blocklist. The app.py source is truncated, so the remainder of the server could not be reviewed. Supply chain analysis found 6 known vulnerabilities in dependencies (0 critical, 3 high severity).

Pulse402 — Dual-Chain (Base + Solana) x402 Data Oracle

Pulse402 is an autonomous, high-frequency data oracle designed specifically for autonomous AI agents and trading bots. It streams verified, read-only market intelligence and pre-trade security checks over HTTP and MCP, settling micropayments natively over the x402 V2 protocol on both Base L2 (eip155:8453) and Solana Mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp).

The canonical service is hosted at https://pulse402-oracle.onrender.com and proxied globally with zero latency via Cloudflare Workers at https://pulse402-oracle.ak10082247.workers.dev.

Every response preserves its original observation timestamp and a strict 10-second acquisition TTL. Outages and stale quotes are reported transparently before payment settlement.

2. Dual-Chain Settlement Infrastructure

Pulse402 accepts gasless, partial-signed x402 V2 authorizations on both major agent ecosystems:

A. Base Mainnet (eip155:8453)

  • Asset: Circle USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, 6 decimals)
  • Standard: EIP-3009 TransferWithAuthorization (requires zero gas / 0 ETH from the buyer)
  • Merchant Recipient: 0x80E0Ae84679b7f11bE171DaADd492FBECf628cd6
  • Settlement: Verified through Coinbase CDP Facilitator & PayAI Facilitator (https://facilitator.payai.network)

B. Solana Mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp)

  • Asset: Native SPL USDC (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v, 6 decimals)
  • Standard: SPL Token TransferChecked inside a sponsored v0 VersionedTransaction (requires zero gas / 0 SOL from the buyer)
  • Merchant Recipient: 9wuMysgXwNhtQeqJgGByAiMYc4EjzZ5wUSmnjrrt3ffh
  • Merchant USDC ATA: DD3A7jaXFeHcif9eYj6Vhomuxypat5Yxi8ow6wxz27yL
  • Sponsored Fee Payer: CjNFTjvBhbJJd2B5ePPMHRLx1ELZpa8dwQgGL727eKww (relayed via PayAI Facilitator)

3. High-Frequency Prepay Session Pass (POST /v1/pass/prepay)

High-frequency algorithmic bots and multi-agent swarms can eliminate on-chain signing latency and save 60%–80% on fees by activating a prepaid session pass:

  1. Purchase: Send a one-time $10.00 USDC payment on Base or Solana to POST /v1/pass/prepay.
  2. Receipt: Server returns a cryptographically secure session_token with 1,000 prepaid calls valid for 7 days.
  3. Execution: Include the header X-Pulse-Session: <token> and Idempotency-Key: <uuid> on any paid endpoint.
  4. Zero Latency: Calls execute instantly without waiting for on-chain signature verification or facilitator relay.

4. Model Context Protocol (MCP) & IDE Integration

Pulse402 runs a production Model Context Protocol (MCP) JSON-RPC 2.0 server at: https://pulse402-oracle.ak10082247.workers.dev/mcp

Connecting in Cursor, Windsurf, Zed, or Claude Desktop
