# PyYAML OSV Vulnerability Disclosure Timeline

> PyYAML OSV Vulnerability Disclosure Timeline 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 a chronological vulnerability disclosure timeline for a specific version of the PyPI package pyyaml, sourced from the OSV (Open Source Vulnerabilities) database.

## 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-osv-vulnerability-disclosure-timeline-1349a7cd -d '<json body>'
```

Example prompt: Can you pull up the full vulnerability disclosure timeline for pyyaml version 6.0.1 from the OSV database so I can audit its security history?

## When to prefer this

Use this endpoint when you specifically need the OSV-sourced vulnerability disclosure timeline for the pyyaml PyPI package. It is ideal for security audits, compliance checks, dependency review pipelines, or developer tooling that needs structured CVE/OSV history scoped precisely to pyyaml. Prefer this over a general OSV API call when you want a pre-scoped, ready-to-query endpoint without needing to build OSV query logic yourself.

## Known failure modes

- Unknown or misspelled version returns empty results or error
- 'latest' resolution may lag behind the actual PyPI registry if cache is stale
- Pagination token errors if page_token is malformed or expired
- No vulnerabilities found for a given version if none are recorded in OSV
- Rate limiting or payment failure if USDC balance is insufficient

## How this service works

pyyaml Vulnerability disclosure timeline: Vulnerability disclosure timeline for PyPI package pyyaml, from OSV. Accepts an exact version; latest resolves the registry version. Scope is the named package only.

## Output

A paginated chronological timeline of vulnerability disclosures for the specified pyyaml version, including OSV IDs, CVE references, disclosure dates, severity information, affected version ranges, and fix versions — sourced from the OSV database.
