How this service works
Deterministic paid checks for autonomous-agent sellers to validate x402 payment compatibility and agent tool schemas before publishing.
Output
Returns a JSON object with a numeric compatibility score (0-100), a list of individual audit checks performed, the target URL, the x402 challenge object, a boolean indicating full x402 compatibility, the HTTP status code observed (e.g. 402), and the detected x402 protocol version.
Example use cases
Pre-publish x402 compatibility check
“Before I list my new agent tool on the marketplace, can you audit https://my-agent-api.example.com/v1/search with a POST method to confirm it's x402-compatible and score how ready it is?”
Debugging a failing 402 handshake
“My agent tool at https://api.myservice.dev/v1/analyze keeps failing x402 payment handshakes — can you run an audit on it via POST and tell me exactly which checks are failing?”
Validating tool schema before agent integration
“I'm about to integrate https://tools.myplatform.io/v1/generate into an agent fleet — please audit it with a GET request to verify the tool schema is correct and it scores well for x402 payment compatibility.”
Technical details
Endpoint
POSThttps://agent-seller-ops.inboxtzdjqv.workers.dev/v1/x402-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you are an autonomous agent seller preparing to publish a tool endpoint and need a deterministic, paid, objective audit of x402 payment compatibility and tool schema correctness. Prefer this over manual testing when you need a scored, structured report that can be programmatically consumed, and especially before listing on agent marketplaces or facilitators that require x402 compliance.
Side effects
- Target URL is unreachable or returns unexpected non-402 status — audit may report incompatible with failed checks
- Malformed input URL causes validation error before reaching the target
- Target endpoint does not implement x402 at all — score of 0 and compatible:false returned
- Network timeout reaching the target endpoint — request may fail or return partial results
- Invalid method enum value in request body causes schema rejection
