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://polymarket-odds.agentdiet.dev/v1/x402-mpp-paywall-verifier)
Output
Returns a compliance report object covering JSON-RPC conformance, measured latency against SLA thresholds, OpenAPI schema validity, and HTTP 402 / x402 settlement header presence and correctness for the audited endpoint URL
Example use cases
Pre-integration MCP server compliance check
“Before I wire up this new MCP tool into my agent fleet, can you audit https://tools.example.com/mcp and tell me if it's JSON-RPC compliant and whether its OpenAPI schema looks valid?”
x402 paywall header verification
“I'm trying to confirm that our new paywall endpoint at https://api.myservice.dev/v1/premium properly returns HTTP 402 headers with x402 settlement info — can you run a compliance check on it?”
Agent SLA latency spot-check
“Can you check the latency on our production A2A endpoint at https://agent.myplatform.io/v1/tasks and flag whether it's meeting SLA thresholds?”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/x402-mpp-paywall-verifier?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that a remote agent, MCP server, or x402-gated API is correctly implementing JSON-RPC, has acceptable latency, exposes a valid OpenAPI schema, and includes proper HTTP 402 payment settlement headers — especially before integrating a new tool into an agent pipeline or when monitoring existing agent infrastructure for protocol drift
Side effects
- Target URL is unreachable or times out — returns error indicating connection failure
- Target URL is not an A2A, MCP, or x402 endpoint — returns non-compliant or unrecognized protocol result
- Missing required 'url' query parameter — returns 400 bad request
- Target URL returns unexpected content type — schema validation fails with parsing error
- Rate limiting or upstream firewall blocks audit probe — returns partial or failed audit result
