# CodePulse PyPI Registry Lookup

> CodePulse PyPI Registry Lookup is a paid API for AI agents from codepulse-api.hahavoid0.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Looks up metadata for a Python package on the PyPI registry, returning author, version, and support status.

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 codepulse-pypi-registry-lookup-3b034cc8 -d '<json body>'
```

Example prompt: Can you look up the PyPI registry entry for the 'requests' package and tell me the current version and who the author is?

## When to prefer this

Use this endpoint when you need quick, structured metadata about a Python package from PyPI — especially version and authorship — without scraping the PyPI website yourself. Prefer it over raw web scraping for PyPI data because the response is structured JSON with a confidence indicator. Best suited for single-package lookups in agent workflows that need pip/PyPI context at low cost ($0.01 per call).

## Known failure modes

- Package not found on PyPI — may return unsupported or low-confidence result
- Misspelled package name returns no match or incorrect metadata
- Data may lag real-time PyPI by the reported data_as_of date
- Network or worker timeout for slow registry responses

## How this service works

Fetches package descriptions, requirements, and release version numbers from PyPI.

## Output

Returns a JSON object with the package author name, current version, a boolean 'supported' flag, a confidence level (e.g. 'high'), the data freshness date (month/year), and any warnings or disclaimers about the information.
