## 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 supremeai-pypi-package-lookup-df6475ab -d '<json body>'
```

Example prompt: Can you look up the PyPI metadata for the 'httpx' package — I want to know its latest version, license, required Python version, and how many dependencies it has?

## When to prefer this

Choose this endpoint when you need a quick, structured snapshot of a PyPI package's metadata in a single call — ideal for dependency vetting, license compliance checks, or Python version compatibility analysis. Prefer it over scraping PyPI manually or calling the raw PyPI JSON API when you need a normalized, agent-friendly response with key fields pre-extracted.

## Known failure modes

- Package name not found on PyPI — returns an error or empty result
- Typo in package name causes no-match response
- Package exists but has incomplete metadata (e.g. missing license or homepage fields)
- PyPI API upstream timeout causing delayed or failed response
- Private or yanked packages may return incomplete data

## How this service works

Pay-per-call tools for AI agents: x402 pre-flight checks (is this endpoint safe to pay?), web pages as clean markdown (with optional JavaScript rendering), Latin American tax-ID validation, npm/PyPI/GitHub lookups, and URL health checks. No API keys, no accounts — pay per request in USDC.

## Output

A structured JSON object containing the package's latest version string, SPDX license identifier, one-line summary description, minimum required Python version, number of declared dependencies, homepage URL, and total number of historical releases on PyPI.
