## 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 api-delx-ai-04422374 -d '<json body>'
```

Example prompt: Can you check the security.txt file for stripe.com and tell me the security contact email, disclosure policy URL, and any trust or acknowledgment links listed there?

## When to prefer this

Use this endpoint when you need to identify the correct security contact or responsible disclosure channel for a domain before reporting a vulnerability, performing outreach, or assessing a domain's security posture. Prefer this over generic web scraping when you specifically need structured security.txt data including contacts, PGP keys, and policy links.

## Known failure modes

- Domain does not have a security.txt file — returns not-found or empty result
- Domain is unreachable or returns non-200 status — returns fetch error
- security.txt file exists but is malformed or unparseable — partial or empty fields returned
- Domain input is invalid or missing — returns validation error
- Rate limit exceeded — returns 429 or payment required error
