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 strale-pypi-package-info-5c3deae2
```

Example prompt: Can you look up the PyPI package info for 'requests' — I want to know the latest version, license, and a short description?

## When to prefer this

Use this endpoint when you need authoritative, auditable PyPI package metadata with a cryptographic chain hash for compliance or trust purposes, and when operating within an x402 micropayment workflow. Prefer over direct PyPI API calls when auditability and multi-country data trust guarantees matter.

## Known failure modes

- Package not found on PyPI — returns an error or empty result
- Misspelled package name returns no match
- PyPI registry temporarily unavailable causes timeout or upstream error
- Payment failure (insufficient USDC balance) prevents the call from completing

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns PyPI package metadata including the package name, latest version, description, author, license, homepage URL, dependencies, and release history — with a cryptographic audit record attached to every response.
