# pyyaml Known Vulnerability List (OSV)

> pyyaml Known Vulnerability List (OSV) is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Returns known security vulnerabilities for a specific version of the PyPI package pyyaml, sourced from the OSV (Open Source Vulnerabilities) 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 pyyaml-known-vulnerability-list-osv-c1e5872b -d '<json body>'
```

Example prompt: Can you pull up the known security vulnerabilities for pyyaml version 6.0.1 from the OSV database?

## When to prefer this

Use this endpoint when you need vulnerability data specifically for the pyyaml PyPI package and want OSV-sourced advisories. It is scoped exclusively to pyyaml, making it faster and more targeted than a general-purpose vulnerability lookup API. Prefer this when building Python dependency auditing pipelines, CI/CD security gates, or vulnerability dashboards focused on pyyaml.

## Known failure modes

- Unknown or malformed version string returns empty or error response
- Pagination token invalid or expired causes request failure
- Rate limits or payment failures result in 402 or 429 errors
- Package name overridden incorrectly may return no results
- Network timeouts if the upstream OSV data source is unavailable

## How this service works

pyyaml Known vulnerability list: Known vulnerability list for PyPI package pyyaml, from OSV. Accepts an exact version; latest resolves the registry version. Scope is the named package only.

## Output

A list of known security vulnerability advisories for the specified pyyaml version from the OSV database, including advisory IDs, CVE references, affected version ranges, severity details, and descriptions. Supports pagination via page_token for large result sets.
