● healthy agent-verification-security

Independent trust & safety oracle + payment guard for x402. Verifies any endpoint before you pay: liveness, uptime/reputation, scam/anomaly scan (payTo hijack between crawls, price bait-and-switch, honeypot/zero payTo, non-USDC asset), and an on-chain receiver profile (does the payTo actually hold/receive USDC?). Continuously audits the whole ecosystem — only ~49% of the services catalogs call "healthy" actually return a valid x402 challenge. Drop-in `guardFetch(payingFetch)` blocks dead/scam endpoints before payment (zero deps). Free `/verify` + live `/status` observatory; paid `/trust` deep check. ([guard SDK](https://www.npmjs.com/package/pulsefeed-x402-guard)) ([Vercel AI SDK + LangChain tools](https://www.npmjs.com/package/pulsefeed-x402-ai-tools)) ([MCP](https://www.npmjs.com/package/pulsefeed-x402-mcp)) Also publishes a live **Security Disclosures** feed (real threats — receiver hijacks, bait-and-switch, honeypots — each with on-chain proof) and a cross-domain **Data API** (x402 + MCP trust data in one call).
