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://shopify-spy.agentdiet.dev/v1/preflight)
Output
Returns a structured compliance report covering: JSON-RPC protocol adherence, measured latency against SLA thresholds, OpenAPI schema validity, and HTTP 402 / x402 v2 settlement header correctness for the audited URL.
Example use cases
Pre-integration MCP server compliance check
“Before I wire up this MCP server at https://mcp.partner.io/v1 into my agent pipeline, can you run a full compliance audit — check JSON-RPC, OpenAPI schema, and latency SLA?”
x402 payment header verification
“I just deployed an x402 micropayment endpoint at https://api.myagent.dev/v1/data — can you audit it to confirm the HTTP 402 settlement headers are configured correctly per the x402 v2 spec?”
A2A agent SLA monitoring spot-check
“Can you spot-check https://agent.acmecorp.ai/a2a for latency SLA compliance and tell me if it's meeting the expected response time thresholds and passing JSON-RPC validation?”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate that a specific remote agent, MCP server, or x402/HTTP 402 payment-enabled API URL conforms to protocol standards before integrating it into an agent pipeline. It is purpose-built for JSON-RPC compliance, SLA latency checks, and HTTP 402 payment header auditing in the A2A/MCP/x402 ecosystem — making it the right choice when generic HTTP health checks or OpenAPI linters lack protocol-specific knowledge.
Side effects
- Target URL is unreachable or times out — audit fails with connectivity error
- Invalid or malformed URL provided — returns validation error
- Target service returns unexpected non-standard responses that cannot be parsed
- Remote endpoint blocks probe requests (firewall/auth) — partial or empty results
- x402 headers absent or malformed — reported as non-compliant rather than error
