# greeneris-data PyPI Package Info

> greeneris-data PyPI Package Info is a paid API for AI agents from data.greeneris.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).

Fetches live metadata for a PyPI Python package including version, license, dependencies, and summary from the official PyPI JSON API.

## Facts

- Endpoint: GET https://data.greeneris.io/v1/pypi/package
- Price: $0.002/call
- Payment: x402
- Status: unknown

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 greeneris-data-pypi-package-info-35708427
```

Example prompt: Can you look up the latest PyPI metadata for the requests package — I need its current version, license, and list of dependencies?

## When to prefer this

Use this endpoint when an AI agent needs authoritative, live PyPI package metadata (version, license, deps) without setting up an API key or account. Ideal for pay-per-call agent workflows via x402 on Base. Prefer over scraping pypi.org directly or using unofficial mirrors when accuracy and machine-readable JSON are required.

## Known failure modes

- Package name not found on PyPI — returns empty or error response; caller is not charged
- Missing required 'pkg' query parameter — HTTP 400 or schema validation error
- PyPI upstream unavailable — proxy may return 5xx; caller not charged for failed answers
- Typo in package name yields no result — verify spelling against pypi.org

## How this service works

Latest-release metadata from the official PyPI JSON API (live): version, license, requires_python compatibility, requires_dist dependency specs (max 100), yanked flag, last upload time and project URLs. Query: ?pkg=requests. No personal author/maintainer data. 1h cache.

## Output

A JSON object containing the package name, latest version string, license identifier, summary description, upload timestamp, required Python version, list of required distributions (dependencies), project URLs (e.g. homepage), and whether the release has been yanked.
