## 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 vulnfeed-dependency-vulnerability-scanner-5827777d -d '<json body>'
```

Example prompt: Can you scan these packages for known vulnerabilities and give me EPSS scores for anything found: lodash@4.17.11, express@4.17.1, and requests==2.25.0?

## When to prefer this

Use this endpoint when you need EPSS-scored vulnerability data for a specific list of software packages — especially useful in CI/CD pipelines, dependency audits, or when you want exploit-probability scoring (EPSS) alongside CVE listings rather than just raw CVE counts.

## Known failure modes

- Empty packages array returns no results
- Unknown or misspelled package names may return no vulnerabilities found (false negative risk)
- Network or upstream data source unavailable returns error
- Malformed package identifiers may cause validation errors
- Rate limiting or payment failure may prevent scan from completing

## How this service works

Dependency vulnerability scanner with EPSS scoring. MCP server + x402 micropayments.

## Output

Returns an array of per-package vulnerability results including EPSS scores, plus aggregate counts of total packages scanned, affected packages, and total vulnerabilities found.
