## 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 http-cache-cors-cookie-policy-evidence-snapshot-68cd0217 -d '<json body>'
```

Example prompt: Capture an HTTP cache, CORS, and cookie policy evidence snapshot for https://example.com so I have documented proof of what headers and policies the server is actually returning.

## When to prefer this

Choose this endpoint when you need documented, timestamped evidence of a website's HTTP cache headers, CORS configuration, and cookie policy — particularly for compliance auditing, security reviews, or debugging cross-origin issues. Prefer this over manual inspection when you need a reproducible, paid-for evidence artifact rather than a one-off curl command.

## Known failure modes

- Payment failure or insufficient USDC balance — purchase rejected
- Invalid or unreachable target URL — job fails during fetch
- Target server blocks automated requests — incomplete header capture
- Job timeout if target URL is slow to respond
- Malformed service ID — 404 or bad request error

## How this service works

Purchase: HTTP Cache, CORS & Cookie Policy Evidence Snapshot

## Output

Returns a job_id, status string, and thread_id representing the initiated snapshot job. The agent can use the job_id to poll for completion and retrieve the actual evidence data (cache headers, CORS policy, cookie headers) once the job finishes.
