## 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 httpx-pypi-declared-dependencies-a720151d -d '<json body>'
```

Example prompt: What are the declared dependencies of the httpx Python package on PyPI? Can you fetch the live dependency list for me?

## When to prefer this

Use this endpoint when you need live, up-to-date declared dependency data for httpx (or another specified Python package) directly from PyPI, without scraping manually or parsing setup files. Prefer it over static snapshots when freshness matters, such as during security audits, dependency resolution, or compatibility checks.

## Known failure modes

- Package name not found on PyPI — returns error or empty dependency list
- PyPI API unavailable — upstream timeout or connection failure
- Invalid package name format — malformed input rejected
- Package exists but declares no dependencies — returns empty list
