# GitHub Security Advisory Feed for PyPI Packages

> GitHub Security Advisory Feed for PyPI Packages is a paid API for AI agents from oracles-production.up.railway.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns reviewed GitHub security advisories (GHSAs) for PyPI packages published since a given timestamp, each scored by severity with affected package details and source links.

## Facts

- Endpoint: GET https://oracles-production.up.railway.app/v1/ghsa-pip/changes
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 github-security-advisory-feed-for-pypi-packages-810581ba
```

Example prompt: Show me all GitHub security advisories for PyPI packages detected since 2025-01-01T00:00:00Z with a significance score of at least 7, up to 50 results.

## When to prefer this

Use this endpoint when you need a structured, severity-scored feed of new GitHub security advisories specifically for PyPI/pip packages, with filtering by recency and minimum significance. Prefer it over raw GitHub Advisory search when you need pre-scored, change-feed semantics (i.e., only what's new since a known timestamp) rather than full-text search, and when you want a companion to the LLM-written digest endpoint for raw data access.

## Known failure modes

- Invalid `since` datetime format returns a 400 bad request
- `min_significance` or `limit` out of allowed range (1–10 and 1–500 respectively) returns validation error
- No advisories matching the filters returns an empty `changes` array with count 0
- Payment not provided or rejected returns 402 Payment Required
- Service unavailable or upstream GitHub Advisory DB unreachable returns 5xx

## How this service works

New security vulnerabilities and CVEs affecting PyPI packages published since a timestamp (GitHub's reviewed advisory database) — each with its CVE ID, CVSS/severity score, affected package names, and a link. Answers "did a dependency I use get a new CVE or vulnerability I should patch?"

## Output

A JSON object containing a count of matching advisories, the data source name, and an array of advisory change objects — each with a GHSA entity ID, title, plain-language summary, severity/significance score (1–10), detailed metadata, a primary source URL for verification, the timestamp it was detected, and its effective date.
