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/x402-mpp-paywall-verifier)
Output
Returns a compliance audit report covering JSON-RPC conformance, measured latency against SLA thresholds, OpenAPI schema validity, and HTTP 402 / x402 v2 payment header correctness for the submitted target URL
Example use cases
Pre-integration agent endpoint check
“Before I wire this new MCP server into my swarm, can you run a full compliance audit on https://tools.mycompany.ai/mcp — I need to know if it's JSON-RPC compliant, what its latency looks like, and whether the OpenAPI schema is valid?”
x402 paywall configuration verification
“I just set up an HTTP 402 paywall on https://api.agentstore.dev/v1/data-feed — can you check if the x402 v2 settlement headers are properly configured and the payment flow would work for an AI agent hitting it?”
Third-party agent SLA due diligence
“We're evaluating a vendor's A2A endpoint at https://vendor-agent.example.com/a2a before signing an SLA — can you audit it for protocol compliance, latency, and whether it correctly handles HTTP 402 payment responses?”
Technical details
Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/x402-mpp-paywall-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that a specific agent, MCP server, or x402-gated API meets protocol compliance standards before integrating it into an agent pipeline, swarm, or marketplace — especially when HTTP 402 payment header correctness or JSON-RPC conformance is a concern.
Side effects
- Target URL is unreachable or times out — returns connectivity error
- Invalid or malformed URL provided — returns validation error
- Target endpoint returns unexpected protocol or non-standard responses — partial audit with warnings
- x402 payment required to access this auditor endpoint itself — HTTP 402 returned if payment not settled
- Target URL blocks probe requests — audit may be incomplete
