Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 onchain-risk-agentdiet-dev-real-time-open-source-package-cve-ghsa-c5a44558
```

Example prompt: Can you check if the PyPI package 'requests' has any known CVEs or GHSA security advisories, and tell me which versions have patches?

## When to prefer this

Use this endpoint when you need real-time, live vulnerability intelligence from OSV.dev for PyPI, npm, Go modules, or Rust crates — particularly when checking CVEs and GHSA advisories with patched version guidance. Prefer this over static NVD lookups or offline databases when up-to-date advisory data is critical for CI/CD pipelines, dependency auditing, or security triage workflows.

## Known failure modes

- Package not found in OSV.dev database — returns empty or no vulnerabilities found
- Invalid ecosystem prefix causes malformed query — returns error or unexpected results
- OSV.dev upstream API unavailability causes request failure
- Malformed package identifier format results in a parsing error
- Package with no known vulnerabilities returns empty advisory list, which may be misread as an error

## How this service works

Queries live Google OSV.dev vulnerability intelligence for any PyPI, npm, Go, or Rust crate and returns active CVEs, GHSA advisories, and patched versions. (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/maven-vuln-scanner)

## Output

Returns a structured response containing active CVE identifiers, GHSA advisory details, severity information, affected version ranges, and recommended patched versions for the queried open-source package from live OSV.dev intelligence.
