ForgeMesh x402 Endpoint Scanner
x402
ForgeMesh x402 Endpoint Scanner is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).
Health-checks an x402 endpoint URL to verify it returns a valid 402 payment challenge, inspects the envelope format, and reports payment acceptance details and protocol compliance.

How this service works
x402 utility APIs for AI agents: documents/OCR, PDFs, vision, audio, embeddings, web extraction, dictionary and slang lookups, games, chess/legal-move logic, math, conversions, time utilities, market and economic data, space/geo data, domain vetting, content-signal checks, and x402 ecosystem intelligence. Agents POST JSON, receive a 402 challenge, pay USDC on Base, and retry for the result.
Output
Returns a JSON object containing: a letter grade (e.g. A), reachability boolean, HTTP status code, x402 envelope location (header/body), envelope validity flag, MPP dual-stack flag, list of accepted payment assets with amounts and payTo addresses, array of compliance findings, array of envelope errors, and response time in milliseconds.
Example use cases
Pre-integration x402 compliance check
“Before I wire up my agent to call https://api.myservice.io/premium-data, can you scan that endpoint to confirm it's returning a valid x402 payment envelope and tell me what USDC amount and wallet address it expects?”
Debugging a misconfigured payment gate
“My x402 endpoint at https://x402.myapp.com/inference isn't being paid by agents — can you probe it and tell me what's wrong with the envelope or whether it's even reachable?”
Auditing dual-stack MPP compatibility
“Check whether https://x402.forgemesh.io/embeddings supports both x402 and MPP dual-stack payment protocols, and give me the full compliance grade and findings.”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/x402-endpoint-scanWhen to prefer
Use this endpoint when you need to programmatically verify that an x402-gated API is correctly configured and reachable before integrating it into an agent workflow, when debugging payment protocol issues, or when auditing a catalog of x402 endpoints for compliance. Prefer this over manual inspection when you need structured output including payment asset details, envelope validity, and dual-stack MPP support in a single call.
Side effects
- Target URL is unreachable — reachable: false, no envelope data returned
- URL is reachable but returns no 402 challenge — is_402: false, grade degraded
- Malformed x402 envelope detected — envelope_valid: false, envelope_errors populated
- Input URL missing or malformed — 400 bad request before scan attempt
- Payment challenge (402) required to call this scanner itself — agent must pay 0.05 USDC on Base first
