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://defi-yield.agentdiet.dev/v1/bazaar-verifier)
Output
Returns a structured compliance report covering: JSON-RPC protocol conformance, measured latency vs SLA thresholds, OpenAPI schema validity, and presence/correctness of HTTP 402 x402 payment settlement headers for the audited URL.
Example use cases
Pre-launch agent endpoint compliance check
“Before I publish my agent to the marketplace, can you run a full compliance audit on https://my-agent.example.com/v1/mcp — I need to know if it passes JSON-RPC, OpenAPI schema, and HTTP 402 settlement header checks.”
Debugging x402 payment header failures
“My x402 service at https://api.myservice.dev/pay keeps failing payment flows — can you audit that URL and tell me whether it's returning the right HTTP 402 settlement headers?”
Verifying third-party MCP server SLA
“I'm integrating a vendor's MCP endpoint at https://vendor.example.io/mcp into my agent stack — can you check its latency SLA and JSON-RPC compliance before I commit to using it?”
Technical details
Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/bazaar-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402-enabled service meets protocol compliance requirements — specifically JSON-RPC conformance, OpenAPI schema validity, latency SLA, and HTTP 402 payment header standards — before integrating it into an agent pipeline or listing it on a marketplace.
Side effects
- Target URL is unreachable or times out — audit fails with connectivity error
- Target URL returns non-standard responses that cannot be parsed for compliance
- Invalid or malformed URL provided as input — validation error returned
- Target service blocks automated probes — incomplete audit results
- HTTP 402 headers absent or malformed — reported as compliance failure
