# OSV Vulnerability Detail Lookup

> OSV Vulnerability Detail Lookup is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-15).

Fetches the full OSV.dev advisory record for a single vulnerability ID (OSV, GHSA, PYSEC, RUSTSEC, or CVE), including summary, severity, affected package ranges, fixed versions, references, and aliases.

## Facts

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 osv-vulnerability-detail-lookup-8a1841a3 -d '<json body>'
```

Example prompt: Can you pull the full OSV advisory for CVE-2021-44228 — I need the severity, affected package version ranges, fixed versions, and any aliases listed in the OSV database.

## When to prefer this

Use this endpoint when you need the authoritative, structured OSV.dev advisory for a specific known vulnerability ID — especially when you need fixed versions, affected package ranges, or cross-ecosystem alias resolution. Prefer this over raw NVD queries when working with open-source package ecosystems (PyPI, crates.io, npm, Go, etc.) since OSV normalizes data across all of them. Choose this when you already have a specific ID and need full detail, rather than when you need to search or scan a codebase.

## Known failure modes

- Unknown or malformed vulnerability ID returns an error or empty result
- Newly published CVEs not yet indexed in OSV.dev will not be found
- Rate limiting or payment failure (x402) results in a 402 or 429 response
- Network timeout if OSV.dev upstream is slow
- IDs from unsupported schemas may not resolve correctly

## How this service works

Full OSV.dev advisory for one vulnerability ID (OSV, GHSA, PYSEC, RUSTSEC or CVE): summary, severity, affected package ranges, fixed versions, references, aliases. Keyless.

## Output

Returns the complete OSV.dev advisory object for the requested vulnerability ID, including: human-readable summary, CVSS or severity score, list of affected packages with version ranges and ecosystems, fixed version identifiers, external references (NVD, GitHub, etc.), and all known aliases (e.g. a GHSA may alias a CVE and vice versa).
