IMPERIUM PREFLIGHT – Multi-Protocol Readiness Auditor (x402, ERC-8004, IETF MPP) is a paid API for AI agents from preflight.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-01).
Runs an automated 8-gate pre-flight readiness audit against a given HTTP endpoint to verify compliance with x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A v0.3.0 agent cards, OASF records, and ERC-8004 identity standards.

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 top-level status field ('ok' or error), a data object containing gate-by-gate compliance results for each of the 8 audited standards, and an roi_proof object including a compression_ratio_pct metric indicating how efficiently the audit results are encoded.
Example use cases
Pre-launch x402 compliance check
“Before I publish my payment-gated API, can you audit https://api.myproject.dev/data with a GET request to confirm it's fully ready for x402 v2 and IETF MPP — I want a gate-by-gate breakdown?”
ERC-8004 identity readiness verification
“Check whether my agent endpoint at https://agent.mycompany.ai/identity passes the ERC-8004 identity and A2A v0.3.0 agent card compliance gates — run it as a GET and tell me what's failing.”
Multi-facilitator listing pre-flight
“I'm about to list my API on x402scan and need to know it's ready — can you run the 8-gate pre-flight audit on https://service.mybrand.io/api using GET and report any compliance gaps with Dexter gas floor or OASF records?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/mpp-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single automated pass that checks compliance across multiple emerging agent and payment protocols simultaneously (x402 v2, ERC-8004, IETF MPP, A2A, MCP, OASF) rather than running separate validators for each standard. Especially valuable before listing an API on a facilitator marketplace or deploying a payment-gated agent service.
Side effects
- Target URL is unreachable or returns no response — audit cannot complete
- Target endpoint does not expose required protocol headers — gates fail with missing-header errors
- Invalid or malformed URL passed as query parameter — returns 400-level error
- Target endpoint actively blocks automated probes — may return partial or inconclusive gate results
- Compliance standards evolve and endpoint may be audited against a stale ruleset if not updated
