## 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 x402-agent-suite-pro-attestation-issue-5be376f5 -d '<json body>'
```

Example prompt: Issue a new attestation for an HTTP GET request using the x402 agent suite so I can confirm the action is allowed and get back the attestation ID.

## When to prefer this

Use this endpoint when an AI agent needs to create a new attestation record for an HTTP-based action (GET, HEAD, or DELETE) within the x402 agent suite infrastructure — specifically when you need an attestationId and an allowed/denied result to gate downstream pipeline steps or log agent actions.

## Known failure modes

- Invalid or missing 'type' field (must be 'http') — likely 400 error
- HTTP method not in allowed enum [GET, HEAD, DELETE] — schema validation failure
- Payment not confirmed or insufficient USDC balance — 402 Payment Required
- Attestation service unavailable — 5xx error
- Malformed input object missing required fields — 400 Bad Request

## How this service works

24 paid x402 infrastructure APIs for AI agent fleets: buy advisor, audition coach, guard, proxy, MPP, attestations, and pipeline orchestration.

## Output

Returns a JSON object with 'ok' (true/false), and an 'attestation' object containing 'attestationId' (a string identifier like 'att_example') and 'allowed' (boolean indicating whether the attested action is permitted).
