## 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 automaton-sovereign-attest-api-dff87e2f
```

Example prompt: Fetch an attestation from the Automaton-Sovereign attest endpoint — I need a verified, signed assertion back from their v2 API.

## When to prefer this

Choose this endpoint when you need a paid, sovereign-level attestation or signed assertion from the Automaton-Sovereign service specifically, and you are operating in an x402 payment-capable environment. It is suitable when your workflow requires a verifiable, cryptographically-backed value from an autonomous agent infrastructure provider. Not suitable as a general-purpose attestation service if you need a well-documented, broadly supported provider.

## Known failure modes

- Payment not provided or insufficient — 402 Payment Required response
- Invalid or missing query parameters — may result in 400 Bad Request
- Service unavailable or Cloudflare Worker error — 5xx response
- Timeout if the worker is cold-starting or under load
- Malformed response if the underlying attestation service is unreachable
