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://x402-audit.agentdiet.dev/v1/x402-mpp-paywall-verifier)
Output
Returns a compliance report object covering JSON-RPC protocol adherence, measured latency against SLA thresholds, OpenAPI schema validity, and HTTP 402 / x402 v2 / IETF MPP payment header presence and correctness for the audited URL.
Example use cases
Pre-deployment MCP server compliance check
“Before I go live, can you run a full compliance audit on https://staging.myagent.dev/mcp — I need to know if it's JSON-RPC compliant, whether the OpenAPI schema looks right, and if the x402 payment headers are properly configured?”
Third-party A2A agent vetting
“I'm about to integrate with a third-party agent at https://partner.agentco.ai/a2a — can you audit it for protocol compliance, latency SLA, and verify it handles HTTP 402 correctly before I wire it into my workflow?”
x402 paywall header verification
“Check whether https://api.example.com/v1/premium properly returns HTTP 402 settlement headers compliant with the x402 v2 and IETF MPP standards — I want to make sure it's set up right for agent-to-agent payments.”

Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/x402-mpp-paywall-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402 paywall URL meets protocol standards — specifically JSON-RPC compliance, latency SLA, OpenAPI schema correctness, and HTTP 402 payment header conformance — before integrating it into an agent workflow or marketplace listing.
Side effects
- Target URL is unreachable or times out — returns error indicating the endpoint could not be probed
- Invalid or malformed URL input — returns validation error
- Target endpoint returns unexpected non-standard responses that cannot be assessed for compliance
- Rate limiting or network restrictions prevent auditing the target URL
- Target endpoint actively blocks probing, resulting in incomplete or partial compliance data
