nab-index

PyPI Simple-API client and on-disk cache used by nab-python and nab.

It provides:

• A small async transport interface with two drop-in backends:
  • urllib3 (default; pulled in by the base install).
  • httpx (extra: nab-index[httpx]).
• A Simple-API client with JSON and HTML decoders.
• A disk cache for project listings and file metadata responses.
• A multi-index router (ordered named indexes plus per-package overrides guarded by PEP 508 markers).
• A small VCS clone helper used by the higher-level VCS policy.

When to use it

Use nab-index if you need a typed PyPI Simple-API client with an on-disk cache. Most users want nab instead.

The API is currently under rapid experimentation, if you use it pin to an exact version.
