# Strale CVE Lookup

> Strale CVE Lookup is a paid API for AI agents from api.strale.io, paid per call via x402, $0.054/call, status unknown (last checked 2026-09-13).

Look up known CVEs (Common Vulnerabilities and Exposures) for a specific software package and version across ecosystems like npm, PyPI, Maven, Go, Cargo, and NuGet

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 strale-cve-lookup-ff9fc7ef
```

Example prompt: Can you check if there are any known CVEs for lodash version 4.17.20 in the npm ecosystem?

## When to prefer this

Choose this endpoint when you need a quick, per-package CVE check with an auditable, cryptographically-hashed response suitable for compliance workflows. It covers 6 major ecosystems (npm, PyPI, Maven, Go, Cargo, NuGet) and is priced per-call at $0.054 USDC, making it suitable for on-demand checks rather than full repository scans. Prefer it over generic vulnerability databases when you need a structured, agent-friendly REST response with built-in audit trail.

## Known failure modes

- Package not found in the specified ecosystem — returns empty result or 404-equivalent
- Invalid or unrecognized ecosystem value — schema validation error
- Missing required parameters (package_name or version) — request rejected
- Unknown CVE database connectivity issue — service error response
- Version string format mismatch — may return no results even if vulnerabilities exist

## How this service works

Look up known vulnerabilities for a package+version via OSV API. Supports npm, PyPI, Maven, Go, Cargo, NuGet. Returns CVEs with severity and fix versions.

## Output

Returns known CVE records associated with the specified package name, version, and ecosystem, including vulnerability identifiers and severity information. Each response includes a cryptographic audit record with chain hashing for traceability and compliance purposes.
