How this service works
Audit one public HTTPS page for 5 USDC on Base: 22 checks and five fixed AEO/GEO remediation slots, with copy-paste code when evidence permits.
Output
A JSON health snapshot including an overall health score (0–100), boolean flags for key checks (resourceBound, challengeValid, baseCanonicalUsdc, bazaarDiscoverable), the target URL/method/status, payment scheme details (amount, network), a unique healthId, a checkedAt timestamp, and a SHA256 report hash. Up to five AEO/GEO remediation slots with copy-paste code are included when issues are detected.
Example use cases
Diagnose undiscoverable x402 endpoint
“My x402 endpoint at https://api.myservice.com/data isn't showing up in agent bazaars — can you audit it and tell me exactly what's failing and how to fix it?”
Pre-launch x402 compliance check
“Before I go live, can you run the 22-check x402 health audit on https://api.newproduct.io/resource and give me all the remediation code I need to pass?”
Fix AEO/GEO discoverability issues
“Run an AEO and GEO audit on https://api.myagentapp.com/endpoint — I want to see my health score and get the copy-paste fixes for any discovery problems.”
Technical details
Endpoint
POSThttps://agent402.dev/x402-healthWhen to prefer
Choose this endpoint when you need to validate and remediate a specific x402-protocol GET endpoint for AI agent discoverability (AEO/GEO). It is purpose-built for the x402 ecosystem on Base/USDC and provides actionable copy-paste fixes, making it superior to generic API health checkers or SEO auditors that have no awareness of x402 protocol requirements, Base network payment schemes, or agent bazaar discovery criteria.
Side effects
- URL does not resolve to a public IPv4 DNS answer — endpoint unreachable
- Target URL does not return HTTP 402 — not a valid x402 endpoint
- Non-GET method specified — only GET is supported
- URL uses HTTP instead of HTTPS — rejected by pattern validation
- Payment failure on Base network — audit not initiated
- Target endpoint requires credentials — not a credential-free public resource
- Malformed URL pattern — fails regex validation
