# HumanMirror API Break Sentinel

> HumanMirror API Break Sentinel is a paid API for AI agents from humanmirror.fr, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Validates and verifies API break events for autonomous systems, returning a sentinel decision on whether an observed incident constitutes a verified API break.

## Facts

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-api-break-sentinel-a37b0b1a -d '<json body>'
```

Example prompt: Run a break sentinel check on this POST event from our payment connector — the event type is 'timeout_error' and here's the incident context — tell me if it's a verified API break.

## When to prefer this

Choose this endpoint when you need a real-time, paid sentinel decision on whether an observed HTTP event in an autonomous system constitutes a verified API break — particularly useful in agent orchestration layers, CI/CD pipelines, or trust governance frameworks where a definitive, third-party verification of API disruption is required before taking automated action.

## Known failure modes

- Missing required fields (type, method, bodyType, body) returns a validation error
- Invalid method enum value (only POST, PUT, PATCH accepted) causes rejection
- Invalid bodyType enum value causes a 400-level error
- Payment not included or insufficient USDC causes 402 payment required
- Malformed JSON body results in parse error
- Unknown or unsupported event_type may result in unverified status

## How this service works

HumanMirror est le control plane des agents autonomes : décision avant action, preuve après exécution, routage machine et gouvernance de flotte.

## Output

Returns a JSON object with 'ok' (boolean), 'status' (e.g. 'verified_success'), and 'product' (product name string), indicating whether the submitted event was verified as an API break by the sentinel.
