# IMPERIUM PREFLIGHT Multi-Protocol Readiness Auditor

> IMPERIUM PREFLIGHT Multi-Protocol Readiness Auditor is a paid API for AI agents from preflight.agentdiet.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-22).

Runs an automated 8-gate pre-flight readiness audit across x402 v2, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, OASF, ERC-8004 identity, and Dexter gas floor compliance for a given HTTP endpoint or text payload.

## Facts

- Endpoint: GET https://preflight.agentdiet.dev/v1/jailbreak-scan?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/imperium-preflight-multi-protocol-readiness-auditor-1e4e463a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_EgXvuNS8c9LiJ8p6mPxJz

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-multi-protocol-readiness-auditor-1e4e463a
```

Example prompt: Can you run a full pre-flight readiness audit on my endpoint using the text 'https://api.myagent.dev/pay' to check whether it passes x402 v2, IETF MPP, A2A v0.3.0, ERC-8004, and MCP Streamable HTTP compliance gates?

## When to prefer this

Choose this endpoint when you need to simultaneously validate an agent endpoint or text payload against multiple emerging agent and payment protocols (x402 v2, IETF MPP, MCP, A2A, ERC-8004, OASF) in a single call rather than running separate audits per protocol. Ideal for pre-deployment readiness gating in CI/CD pipelines or agent marketplace onboarding flows.

## Known failure modes

- Missing required 'type' or 'method' fields returns a validation error
- Unsupported method value outside GET/POST enum causes rejection
- Empty or malformed text query param may produce incomplete gate results
- Network timeout or upstream service unavailability returns non-200 status
- Payload too large for BM25 budget may be truncated silently

## 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 per-gate audit results for all 8 compliance checks, and an roi_proof object including a compression_ratio_pct metric indicating how efficiently the audit summarized the input.
