# SiteSignal OSV Package Vulnerabilities

> SiteSignal OSV Package Vulnerabilities is a paid API for AI agents from trinity-throw-thursday-gravity.trycloudflare.com, paid per call via x402, $0.015/call, status down (last checked 2026-09-15).

Returns bounded OSV (Open Source Vulnerabilities) vulnerability records for a specific package identified by ecosystem, name, and version.

## Facts

- Endpoint: GET https://trinity-throw-thursday-gravity.trycloudflare.com/x402/osv-vulnerabilities
- Price: $0.015/call
- Payment: x402
- Status: down
- Last checked: 2026-09-15

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 sitesignal-osv-package-vulnerabilities-528957db
```

Example prompt: Can you check the OSV vulnerability database for lodash version 4.17.20 in the npm ecosystem and tell me if there are any known security issues?

## When to prefer this

Use this endpoint when you need a quick, per-package vulnerability lookup against the OSV database for a specific ecosystem, name, and version combination. Prefer it over general web searches when you need structured, machine-readable vulnerability data from a canonical source. It covers the five most common ecosystems (npm, PyPI, Maven, Go, crates.io) and is ideal for automated dependency audits or pre-deployment security checks.

## Known failure modes

- Unknown or misspelled package name returns empty results rather than an error
- Unsupported ecosystem (outside npm, PyPI, Maven, Go, crates.io) returns validation error
- Malformed or non-existent version string may return empty results
- Rate limiting or upstream OSV API unavailability causes request failure
- Network timeout from Cloudflare tunnel proxy

## How this service works

Return bounded OSV vulnerability records for one exact package ecosystem, name, and version.

## Output

A bounded set of OSV vulnerability records for the specified package, including vulnerability IDs (e.g. CVE, GHSA), severity ratings, affected version ranges, descriptions, and references to security advisories or patches.
