## 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 klymax402-http-headers-analyzer-74e7663f
```

Example prompt: Can you check the HTTP security headers for https://example.com and tell me the score and any issues you find?

## When to prefer this

Use this endpoint when you need a quick, low-cost programmatic check of a URL's HTTP headers and security posture without setting up a full browser or scanner. Ideal for one-off audits, pre-launch checks, or verifying third-party site header compliance.

## Known failure modes

- Invalid or unreachable URL returns error or empty headers
- Non-HTTP URLs may cause fetch failures
- Timeout if target server is slow or unresponsive
- Malformed URL input causes validation error
- Target site blocking automated requests returns unexpected status codes
