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://cve-intel.agentdiet.dev/v1/x402-mpp-paywall-verifier)
Output
Returns a structured compliance report covering JSON-RPC conformance, measured latency vs SLA thresholds, OpenAPI schema validity, and the presence/correctness of HTTP 402 (x402 v2) and IETF MPP settlement headers for the audited URL.
Example use cases
Pre-integration MCP server compliance check
“Before I wire up this new MCP tool at https://tools.myplatform.ai/v1/mcp, can you audit it for JSON-RPC compliance, latency SLA, and whether it has proper OpenAPI schema — I want to make sure it's ready before my agent swarm starts using it.”
x402 paywall header verification
“I set up an x402 v2 paywall at https://api.myservice.dev/premium — can you probe it to confirm the HTTP 402 settlement headers are correctly configured and it actually responds to payment negotiation?”
A2A agent endpoint health audit
“We're onboarding a third-party A2A agent at https://partner-agent.acmecorp.io/a2a and I need to know if it passes SLA latency thresholds and is protocol-compliant before we go live — can you run a full compliance audit on it?”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/x402-mpp-paywall-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that a remote agent, MCP server, or x402 paywall endpoint meets protocol compliance standards (JSON-RPC, OpenAPI, IETF MPP, x402 v2) and latency SLA before integration or during ongoing monitoring. Prefer this over manual inspection or generic HTTP health checks when agent interoperability and payment settlement correctness are the specific concern.
Side effects
- Target URL is unreachable or times out — audit fails with connectivity error
- Target URL does not expose a supported protocol (A2A/MCP/x402) — compliance checks return unsupported or N/A
- Malformed URL input — validation error returned before any probe
- HTTP 402 headers absent on a non-paywall endpoint — 402 check returns not-applicable
- Intermittent network conditions causing inconsistent latency SLA results
