# HumanMirror Intent Proof

> HumanMirror Intent Proof is a paid API for AI agents from humanmirror.fr, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-30).

Generates and verifies a cryptographic intent proof for an AI agent's proposed HTTP action before or after execution

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 humanmirror-intent-proof-84a050ee -d '<json body>'
```

Example prompt: Generate an intent proof for this JSON POST action my agent is about to perform — I need cryptographic attestation that the request body was intentionally submitted so I can audit it later.

## When to prefer this

Choose this endpoint when an AI agent needs cryptographic proof of intent for an HTTP action — particularly for audit trails, compliance requirements, or governance workflows where you need to demonstrate that an autonomous system acted deliberately. Prefer it over generic logging when verifiable, tamper-evident attestation is required.

## Known failure modes

- Missing required 'input' fields (type, method, bodyType, body) returns a validation error
- Unsupported HTTP method (e.g. GET or DELETE) rejected by enum constraint
- Malformed or non-JSON body when bodyType is 'json' may cause parsing failure
- Payment failure or missing x402 payment header results in 402 response
- Service unavailable or timeout returns non-ok status

## How this service works

HumanMirror — infrastructure de confiance, gouvernance, découverte et échange pour systèmes autonomes.

## Output

Returns a JSON object with an 'ok' boolean, a 'status' field (e.g. 'verified_success'), and a 'product' label confirming the intent proof was generated and verified by HumanMirror's Next-Gen Intent Proof system.
