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, and an roi_proof block including a compression_ratio_pct indicating how efficiently the audit result is encoded. Failures indicate which of the 8 compliance gates were not met.
Example use cases
Pre-launch x402 API compliance check
“Before I go live, can you run a full pre-flight audit on my API endpoint with a GET request to make sure it's compliant with x402 v2 and IETF MPP payment standards?”
ERC-8004 identity readiness verification
“I need to verify that my agent service is ERC-8004 identity compliant — can you run the IMPERIUM PREFLIGHT audit using a GET method and show me which of the 8 gates it passes or fails?”
A2A agent card and OASF record validation
“Can you audit my HTTP endpoint via a GET request using IMPERIUM PREFLIGHT to check whether my A2A v0.3.0 agent card and OASF records are properly configured before I register with a facilitator?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/prompt-guard?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, multi-standard compliance audit covering x402 v2, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, ERC-8004, and OASF in a single automated pass. Prefer it over manual checklist reviews or single-standard validators when preparing an agent-payable API for multi-facilitator deployment.
Side effects
- Missing required 'input' object or 'method' field returns a validation error
- Endpoint unreachable or invalid URL causes audit failure with no gate results
- Non-compliant endpoints return detailed per-gate failure reasons
- Rate limiting or payment failure (x402) blocks the request
- Unsupported method values outside GET/POST cause schema rejection
