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://json-repair.agentdiet.dev/v1/x402-mpp-paywall-verifier)
Output
Returns a structured compliance report covering JSON-RPC conformance status, measured latency vs SLA thresholds, OpenAPI schema validation findings, and analysis of HTTP 402 / x402 payment settlement headers for the target URL.
Example use cases
Onboarding a new MCP tool safely
“Before I integrate this MCP server into my agent stack, can you check whether https://tools.example.com/mcp is JSON-RPC compliant, responds within SLA, and has a valid OpenAPI schema?”
Verifying x402 paywall configuration
“I set up an HTTP 402 paywall on https://mypaywall.dev/v1/agent-service — can you verify the x402 settlement headers are correctly configured and the endpoint passes compliance checks?”
Debugging a failing A2A agent endpoint
“My A2A agent at https://agent.myplatform.io/a2a seems to be timing out — can you audit it for SLA compliance and tell me if there are any JSON-RPC or protocol issues?”
Technical details
Endpoint
GEThttps://json-repair.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, MCP, or x402 endpoint conforms to protocol standards before integrating it into an agent pipeline, or when debugging compliance issues with payment paywalls or JSON-RPC agent APIs. It is specifically suited for x402/HTTP 402 header validation alongside standard SLA and schema checks, making it more specialized than generic API health-check tools.
Side effects
- Target URL is unreachable or returns a non-2xx/402 response — audit may fail or return partial results
- Invalid or missing URL parameter — returns validation error
- Target endpoint has no OpenAPI spec exposed — schema section of report may be empty or indicate absence
- Very slow or timing-out endpoints may cause the audit to fail with a latency-related error
- Non-agent URLs (e.g. plain HTML pages) may return low compliance scores with no meaningful JSON-RPC findings
