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/certify)
Output
Returns a structured compliance report indicating whether the target URL passes JSON-RPC protocol compliance, latency SLA thresholds, OpenAPI schema validity, and HTTP 402 settlement header requirements, along with any specific failures or warnings detected during the audit.
Example use cases
Pre-production agent endpoint certification
“Before I add this new MCP server at https://tools.mycompany.ai/mcp to our production swarm, can you audit it for JSON-RPC compliance, latency SLA, and HTTP 402 header support so I know it's ready?”
x402 payment header verification
“I just deployed an x402 payment endpoint at https://api.mybiz.dev/v1/pay — can you check whether it's returning the correct HTTP 402 settlement headers and passing the IETF MPP compliance checks?”
Agent marketplace listing compliance check
“I want to list my A2A agent at https://agent.startup.io/a2a in a marketplace — can you run a full SLA and OpenAPI schema compliance audit on it so I can confirm it meets the protocol requirements?”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/preflight/certify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific A2A agent, MCP server, or x402-capable URL is protocol-compliant before integrating it into an agent workflow, listing it in a marketplace, or routing live traffic to it. Prefer it over manual inspection or generic HTTP checkers when you specifically need JSON-RPC, OpenAPI, HTTP 402, and latency SLA checks in one call.
Side effects
- Target URL is unreachable or times out — audit fails with connectivity error
- Invalid or malformed URL provided — returns validation error
- Target endpoint returns non-standard or empty responses making compliance undeterminable
- HTTP 402 headers absent or malformed — flagged as non-compliant but audit still returns
- OpenAPI schema missing at target — schema check fails with absence warning
- Rate limiting or firewall at target URL blocks probe requests
