# HumanMirror Automata Checkout Link Guard

> HumanMirror Automata Checkout Link Guard is a paid API for AI agents from humanmirror.fr, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-30).

Validates and guards checkout link events for autonomous systems, returning a verification status indicating whether the checkout action is safe to proceed.

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-automata-checkout-link-guard-729384d8 -d '<json body>'
```

Example prompt: Before I complete this checkout, run it through HumanMirror's Checkout Link Guard — the event type is 'purchase_initiated', the body is JSON, the method is POST, and the available connectors are ['stripe','coinbase'] — tell me if it's verified safe to proceed.

## When to prefer this

Choose this endpoint when an autonomous agent needs a lightweight, paid trust-check on a checkout link event before committing to a purchase action — especially in agentic pipelines where connector identity and event type need cross-checking. Prefer it over generic webhook validators when you need a purpose-built guard layer designed for autonomous commerce and x402-based payment flows.

## Known failure modes

- Missing required fields (type, method, bodyType, body) returns a validation error
- Unsupported HTTP method (e.g. GET or DELETE) rejected by enum constraint
- Unrecognized or malformed connector names may result in an unverified status
- Network timeout or service unavailability returns no response
- Invalid body structure or extra properties rejected due to additionalProperties:false
