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' or error), a data object containing per-gate audit results across all 8 compliance dimensions, and an roi_proof object including a compression_ratio_pct metric indicating how efficiently the audit result was encoded.
Example use cases
Pre-launch agent endpoint compliance check
“Before I go live, can you audit https://api.myservice.dev/agent via GET against all the major agent protocol standards — x402, MCP Streamable HTTP, A2A v0.3.0, and ERC-8004 — and tell me which gates it fails?”
Verify x402 payment readiness for a facilitator
“I'm listing my endpoint on an x402 facilitator — can you run the IMPERIUM pre-flight audit on https://payments.myapp.io/checkout using GET to confirm it passes x402 v2 and Dexter gas floor compliance?”
Audit third-party agent before integration
“I'm thinking of integrating with https://external-agent.partner.com/a2a — can you do a pre-flight readiness check on it with a GET request to see if it's compliant with A2A v0.3.0, OASF records, and IETF MPP before I commit?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/402-compliance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-standard compliance audit across x402 v2, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, OASF, and ERC-8004 simultaneously in a single call, rather than running separate validators for each standard. Particularly useful before listing an endpoint on an x402 facilitator, before integrating a third-party agent, or when building agent infrastructure that must satisfy multiple protocol requirements at once.
Side effects
- Target URL is unreachable or times out — returns error status
- URL fails one or more compliance gates — gates marked as failed in data object
- Invalid or missing URL query parameter — schema validation error
- Target endpoint returns non-standard responses incompatible with audit parsing
- Network errors or DNS resolution failures for the target URL
