# PyYAML CVE and Advisory Reference Mapping

> PyYAML CVE and Advisory Reference Mapping 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 CVE identifiers and security advisory references for a specific version of the PyPI package pyyaml, sourced from OSV.

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-cve-and-advisory-reference-mapping-c591cb03 -d '<json body>'
```

Example prompt: Can you look up all known CVEs and security advisories for pyyaml version 6.0 from OSV?

## When to prefer this

Use this endpoint when you specifically need CVE and advisory data for the pyyaml PyPI package and want structured OSV-sourced results per version. Prefer this over general vulnerability databases when you need a quick, paid, per-call lookup scoped exactly to pyyaml without setting up OSV API credentials yourself.

## Known failure modes

- Unknown or malformed version string returns no results or an error
- Package name override to a non-pyyaml package may return empty or unsupported response
- Rate limiting or payment failure returns HTTP 402 or 429
- OSV upstream data unavailable may cause stale or empty results
- Invalid page_token causes pagination error

## How this service works

pyyaml CVE and advisory reference mapping: CVE and advisory reference mapping for PyPI package pyyaml, from OSV. Accepts an exact version; latest resolves the registry version. Scope is the named package only.

## Output

A mapping of CVE identifiers and OSV advisory references associated with the specified pyyaml version, indicating which known vulnerabilities affect that release. May include advisory IDs, CVE numbers, severity data, and affected version ranges as provided by OSV.
