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/x402-mpp-paywall-verifier)
Output
Returns a structured compliance report covering JSON-RPC protocol adherence, measured latency against SLA thresholds, OpenAPI schema validity, and presence/correctness of HTTP 402 x402 payment settlement headers for the submitted URL.
Example use cases
Pre-deployment MCP server compliance check
“Before I launch my MCP server at https://mcp.mycompany.dev/v1/agent, can you audit it for JSON-RPC compliance, latency SLA, and proper HTTP 402 settlement headers?”
Verifying third-party A2A agent protocol support
“I'm integrating a third-party agent at https://vendor-agent.io/api/v2 — can you check if it's fully A2A and x402 compliant, including OpenAPI schema and payment headers?”
Debugging HTTP 402 paywall on agent endpoint
“My endpoint at https://api.defibot.xyz/v1/query should be returning HTTP 402 x402 payment headers but I'm not sure it's configured right — can you run a compliance audit on it?”
Technical details
Endpoint
GEThttps://defi-yield.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-enabled API meets protocol compliance standards — specifically JSON-RPC correctness, latency SLAs, HTTP 402 payment header format, and OpenAPI schema validity — before integration or deployment. Prefer this over generic HTTP health-checkers when x402/MCP/A2A protocol specifics matter.
Side effects
- Target URL is unreachable or times out — audit fails with connectivity error
- Malformed or missing URL parameter — returns validation error
- Target endpoint returns unexpected content type blocking protocol analysis
- Remote endpoint blocks probing requests (firewall/rate-limit) — partial or empty results
- Non-HTTP URLs or private/internal addresses may be rejected
