## 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 lilambd-exposure-brief-domain-security-scan-5b706256
```

Example prompt: Can you pull the security exposure brief for example.com, focusing on Ivanti Connect Secure and Microsoft Exchange Server vulnerabilities, and show me up to 50 results?

## When to prefer this

Choose this endpoint when you need a quick, paid security exposure snapshot for a specific domain — especially when you want to filter findings by technology stack (e.g. Ivanti, Citrix, Microsoft Exchange) or detect certificate lookalikes. It is well-suited for automated security workflows, vendor risk assessments, and pre-engagement reconnaissance where a structured JSON brief is needed.

## Known failure modes

- Missing required 'domain' parameter returns a validation error
- Invalid domain format may return empty results rather than an error
- Unpaid or failed x402 payment results in 402 Payment Required response
- Requesting an unknown stack vendor:product combo may silently return no stack-filtered results
- Rate limiting or payment issues may cause request failures

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing an array of exposure data items (data), a count of results, and an attribution line crediting the data source license. Each item in the data array represents a discovered exposure, vulnerability, or lookalike finding for the queried domain.
