# SignalDesk AI OSV Vulnerability Lookup

> SignalDesk AI OSV Vulnerability Lookup is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-13).

Checks whether a given npm or PyPI package (and optional version) has known vulnerabilities using the OSV database

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 signaldesk-ai-osv-vulnerability-lookup-15db4669
```

Example prompt: Can you check if lodash version 4.17.15 on npm has any known vulnerabilities in the OSV database?

## When to prefer this

Use this endpoint when you need a quick, paid, per-call vulnerability lookup against the OSV database for a specific npm or PyPI package, especially when integrating security checks into automated agent workflows. It is best suited for single-package lookups in supported ecosystems (npm, PyPI) rather than bulk scanning or ecosystems like Maven or RubyGems.

## Known failure modes

- Missing required 'package' query parameter returns an error
- Invalid or unrecognized ecosystem value (not 'npm' or 'PyPI') may return an error or empty result
- Package not found in OSV database may return zero vulnerabilities rather than an error
- Payment failure (insufficient USDC balance) blocks the request
- Rate limiting or quota exhaustion under free tier may reject the call

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object containing the package name, the version checked, a boolean indicating whether it is vulnerable, and the total number of known vulnerabilities found in the OSV database for that package/version combination.
