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 ('ok' or error), a data object containing gate-by-gate audit results for all 8 protocol checks (x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, OASF, ERC-8004, and others), and an roi_proof block including a compression_ratio_pct metric indicating audit efficiency.
Example use cases
Pre-launch x402 endpoint compliance check
“Before I submit my payment endpoint to the facilitator directory, can you run a full 8-gate pre-flight audit on it to confirm it's x402 v2 and Dexter gas floor compliant?”
ERC-8004 identity readiness verification
“I've set up ERC-8004 identity for my agent service — can you scan it with IMPERIUM PREFLIGHT to verify the identity gates pass before I open it to external agents?”
A2A agent card and MCP server audit
“My A2A v0.3.0 agent card and MCP Streamable HTTP server are set up — run a pre-flight readiness check on them and tell me which of the 8 gates fail so I know what to fix.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/token-scanner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call, multi-protocol compliance sweep across x402, ERC-8004, IETF MPP, A2A, MCP, and OASF standards before deploying or listing an agent service. It is especially useful when you need a structured, gate-by-gate audit report rather than checking each protocol standard manually or separately.
Side effects
- Missing or invalid token parameter returns an error or empty data object
- Endpoint or token not reachable causes a failed gate result rather than a hard error
- Partial compliance returns ok status with individual gate failures flagged in data
- Malformed query parameters may result in 400-level responses
- Service unavailability returns non-ok status
