How this service works
Audits any remote agent or MCP URL for JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP 402 settlement headers. (Live x402 v2, IETF MPP & MCP endpoint at https://agentdiet.dev/v1/x402-verifier)
Output
Returns an audit report covering JSON-RPC compliance status, latency SLA measurement, OpenAPI schema validation results, and HTTP 402 payment settlement header inspection for the target URL — indicating which checks passed, failed, or have warnings.
Example use cases
Verify agent before marketplace listing
“Before I list my agent on a marketplace, can you audit https://mybot.example.com/v1/agent via GET and tell me if it passes x402 compliance — JSON-RPC, OpenAPI schema, and 402 payment headers all included?”
Debug failing x402 payment headers
“My MCP server at https://mcp.myplatform.io/rpc isn't receiving payments properly — can you audit it with a GET request and show me exactly which HTTP 402 settlement headers are missing or wrong?”
Benchmark latency SLA of third-party agent
“I'm evaluating a third-party agent at https://vendor-agent.io/api/v2 for integration — can you run an x402 compliance audit on it via GET and report on its latency SLA and JSON-RPC conformance?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/x402-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that an AI agent, MCP server, or HTTP API endpoint properly implements the x402 payment protocol, JSON-RPC spec, and latency SLAs — especially before integrating, listing, or going live with an agent service. Prefer it over manual inspection or generic HTTP checkers because it specifically understands x402 settlement headers and agent-layer compliance requirements.
Side effects
- Target URL unreachable or returns network error
- Target URL does not implement JSON-RPC at all, producing incomplete audit
- URL missing or malformed in query parameters
- Target endpoint blocks automated audit requests (rate limiting or auth)
- HTTP 402 headers absent entirely, resulting in partial audit with compliance failures
