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://prompt-guard.agentdiet.dev/v1/paywall-check)
Output
Returns a structured audit report covering JSON-RPC compliance status, measured latency against SLA thresholds, OpenAPI schema validation findings, and HTTP 402 / x402 v2 settlement header presence and correctness for the submitted URL.
Example use cases
Pre-integration MCP server compliance check
“Before I add this MCP server to my agent stack, can you audit https://tools.myplatform.ai/v1/mcp and tell me if it passes JSON-RPC compliance, has a valid OpenAPI schema, and meets latency SLA?”
HTTP 402 paywall header verification
“I built an x402-gated API at https://api.mystartup.dev/v1/premium — can you check whether it correctly returns HTTP 402 settlement headers and is x402 v2 compliant?”
Agent fleet SLA audit before production rollout
“We're about to go live — can you run a full compliance audit on https://agent.myfleet.io/a2a to check JSON-RPC adherence, latency SLA, and IETF MPP protocol headers?”
Technical details
Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/paywall-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a programmatic, structured compliance report on a specific agent or MCP URL before integrating it into an agent workflow, when debugging x402/HTTP 402 payment header issues, or when validating latency SLAs and JSON-RPC protocol conformance for A2A services. Prefer it over manual inspection or generic HTTP testing tools when you need simultaneous multi-protocol checks (JSON-RPC, OpenAPI, HTTP 402/x402, SLA) in a single call.
Side effects
- Target URL is unreachable or times out — audit returns connectivity error
- URL does not implement any recognized protocol (A2A/MCP/x402) — returns non-compliant result with no applicable checks
- Malformed or missing URL parameter — returns 400 validation error
- Target endpoint returns unexpected content type — schema validation may be incomplete
- Rate limiting or auth on the target endpoint blocks the probe — audit returns partial or failed results
