# IMPERIUM PREFLIGHT – x402, ERC-8004 & IETF MPP Readiness Auditor

> IMPERIUM PREFLIGHT – x402, ERC-8004 & IETF MPP Readiness Auditor is a paid API for AI agents from preflight.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Runs an 8-gate automated compliance audit on a domain to assess readiness for x402 v2, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, OASF, and ERC-8004 identity standards.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability imperium-preflight-x402-erc-8004-ietf-mpp-readiness-auditor-ed113594
```

Example prompt: Run a pre-flight readiness audit on agentdiet.dev — I need to know if it passes all 8 gates for x402 v2, ERC-8004 identity, and IETF MPP compliance before I go live.

## When to prefer this

Choose this endpoint when you need a structured, multi-standard compliance audit across x402 v2, IETF MPP, MCP, A2A, OASF, and ERC-8004 simultaneously for a single domain. It is ideal for pre-deployment readiness checks before listing a service on x402 facilitators or publishing an A2A agent card. Prefer it over manual per-standard checks when you need a single consolidated 8-gate pass/fail report with ROI proof.

## Known failure modes

- Missing or invalid domain query parameter returns an error status
- Domain is unreachable or does not respond to HTTP — audit gates may partially fail
- Non-compliant domain returns gate failures with specific remediation signals
- Payment not processed (x402 flow failure) results in 402 response before audit runs
- Malformed input schema (wrong method enum or type constant) causes request rejection

## 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 gate-by-gate compliance results, and an roi_proof block including a compression_ratio_pct metric indicating audit efficiency.
