How this service works
Automated 8-gate pre-flight readiness auditor for x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A v0.3.0 agent cards, OASF records, and ERC-8004 identity.
Output
Returns a JSON object with a status field ('ok'), a data object containing per-gate audit results across all 8 compliance checks, and an roi_proof block including a compression_ratio_pct indicating how efficiently the audit payload was delivered.
Example use cases
Pre-launch x402 payment gateway check
“Before I go live, can you audit https://api.myapp.io/checkout with a GET request and tell me if it passes the x402 v2 and Dexter gas floor compliance gates?”
A2A agent card readiness verification
“I'm deploying a new agent — can you run a pre-flight check on https://agent.myproject.dev/card using GET to see if its A2A v0.3.0 agent card and ERC-8004 identity are properly configured?”
MCP Streamable HTTP compliance audit
“Can you audit https://tools.myplatform.com/mcp via GET and check whether it passes the MCP Streamable HTTP and IETF MPP compliance gates before I register it with a facilitator?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/serp-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, multi-standard compliance audit across x402 v2, ERC-8004, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, and OASF in a single call rather than running separate per-protocol checks. It is especially useful for pre-deployment validation of agent endpoints, payment-gated APIs, and facilitator-listed services that must satisfy multiple interoperability standards simultaneously.
Side effects
- Target URL is unreachable or returns non-HTTP response — audit cannot proceed
- Target endpoint does not expose required compliance headers — gates fail with missing-header errors
- Invalid or missing 'type' or 'method' fields in input — returns schema validation error
- Rate limiting or payment failure on the auditor itself — returns 402 or 429
- Target responds with unexpected content type — partial gate results or parsing errors
