## 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 ghsa-composer-php-security-advisories-brief-57658bdb
```

Example prompt: Can you give me a security brief on the most severe Composer and PHP package advisories from the past 30 days? I want an LLM-written digest of what I should be worried about.

## When to prefer this

Use this endpoint when you need a human-readable, LLM-synthesized narrative summary of PHP/Composer security advisories rather than raw GHSA data. Prefer this over the raw advisory detail endpoint when you want a concise brief highlighting the most severe issues, not individual CVE records. Best suited for security digests, automated reports, or alerting workflows targeting PHP/Composer ecosystems specifically — use the PyPI brief sibling for Python packages instead.

## Known failure modes

- No advisories in window: may return empty or minimal brief with basedOnChanges=0
- Invalid 'since' datetime format: returns 400 bad request
- LLM generation failure: falls back to template-based generation (generatedBy='template')
- Payment not provided or insufficient: 402 Payment Required
- Service downtime on Railway: 503 or timeout

## How this service works

LLM-written digest of the most severe new Composer/PHP vulnerabilities (CVEs / advisories) in the window and which packages to patch first.

## Output

Returns a JSON object containing: a 'brief' field with an LLM-written narrative summary of the most severe new Composer/PHP advisories, a 'generatedBy' field indicating whether an LLM or template produced it, and a 'basedOnChanges' integer showing how many advisories were analyzed in the window.
