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 failure), a data object containing per-gate audit results across all 8 readiness checks (x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A agent cards, OASF records, ERC-8004 identity), and an roi_proof object including a compression_ratio_pct metric.
Example use cases
Pre-launch MCP server compliance check
“I'm about to launch my MCP server and need to know if it's fully compliant with MCP Streamable HTTP and x402 v2 — can you run a preflight audit on it and show me which gates pass or fail?”
ERC-8004 identity readiness verification
“Before I register my agent on-chain, can you audit my endpoint for ERC-8004 identity compliance and tell me if there are any issues I need to fix?”
A2A agent card and OASF record validation
“I've set up my A2A v0.3.0 agent card and OASF record and want to confirm they're correctly formatted and compliant — please run the preflight scanner and give me a full readiness report.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/epss-scanner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive multi-protocol readiness check covering x402, ERC-8004, IETF MPP, MCP, A2A, and OASF in a single call rather than running separate protocol-specific validators. Ideal pre-deployment gate for agent and payment-enabled API endpoints that need to be listed on facilitators or agent marketplaces.
Side effects
- Target endpoint unreachable or returns non-200 response — audit cannot complete
- Invalid or missing 'type' or 'method' fields cause 400 Bad Request
- Package parameter pointing to a non-existent or malformed URL returns gate failures
- One or more compliance gates fail, returning specific gate error details in data
- Rate limiting or payment failure ($0.01 USDC) may block the call
