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 for each of the 8 compliance checks (x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, OASF, ERC-8004, and any additional gates), and an roi_proof block including a compression_ratio_pct metric (e.g. 91.4%) indicating how efficiently the audit summary was distilled.
Example use cases
Pre-launch agent endpoint compliance check
“Before I go live, can you audit https://api.myagent.io/tools/search with a GET request to make sure it passes all x402 v2 and ERC-8004 identity gates?”
MCP server Streamable HTTP readiness test
“Run the IMPERIUM PREFLIGHT audit on https://mcp.mycompany.dev/stream using GET mode to verify it meets MCP Streamable HTTP and IETF MPP requirements.”
A2A agent card and OASF record validation
“Check if https://agents.mybrand.xyz/.well-known/agent.json passes the A2A v0.3.0 agent card and OASF record gates in the pre-flight auditor — use GET method.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/distill?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-standard compliance audit covering x402 v2, ERC-8004, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, OASF, and Dexter gas floor in a single automated pass. Prefer it over manual per-standard checkers when pre-launch readiness across the full agentic payment and identity stack matters, or when you need an ROI-proof compression metric to confirm audit efficiency. It is especially suited for developers deploying payment-gated agent APIs who need to validate multi-facilitator compatibility before going live.
Side effects
- Target URL unreachable or returns non-200 — audit may fail or return partial gate results
- Malformed or missing URL parameter — request rejected with validation error
- Endpoint does not implement any of the audited standards — all gates return non-compliant
- Rate limiting or payment failure (x402) — 402 response requiring USDC payment
- Mode parameter not recognized — defaults or errors depending on service behavior
- Timeout on slow target endpoints — incomplete audit results returned
