## 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 delx-commerce-cache-policy-audit-api-c8ebc002 -d '<json body>'
```

Example prompt: Can you audit these HTTP response headers and tell me if there are any cache policy problems — specifically check if Cache-Control, ETag, and Vary are set correctly: {"Content-Type": "application/json", "Cache-Control": null}?

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call audit of HTTP response headers specifically for caching correctness — especially useful in CI/CD pipelines, agent-driven infrastructure reviews, or pre-deployment checks where no signup or subscription is desired and USDC micropayment via x402 is acceptable.

## Known failure modes

- Empty or malformed headers object returns incomplete findings
- Missing required payment (x402) results in 402 Payment Required response
- Headers with non-string values may be rejected by schema validation
- Ambiguous or conflicting cache directives may yield inconclusive risk rating

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object containing a risk rating (e.g. 'review'), a schema version identifier, a list of specific findings such as 'cache_control_missing', and boolean flags indicating whether ETag and Vary headers are present, plus the raw Cache-Control value if found.
