## 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 numpy-pypi-declared-dependencies-37bedb67 -d '<json body>'
```

Example prompt: What are the declared PyPI dependencies for numpy? I want to see what packages it officially lists as requirements.

## When to prefer this

Use this endpoint when you need up-to-date, live declared dependency information for a specific PyPI package without scraping PyPI yourself. It is ideal for dependency auditing, compatibility checking, and automated package analysis workflows where freshness matters.

## Known failure modes

- Unknown or misspelled package name returns an error or empty result
- PyPI API unavailability causes lookup failure
- Package exists but declares no dependencies, returning an empty list
- Rate limiting or network timeouts from PyPI upstream
