placekey-py
placekey-py is a Python library for working with Placekeys, universal location identifiers. It enables conversion between Placekeys and latitude-longitude coordinates, conversion between Placekeys and H3 indices, and calculation of distances between Placekeys. The library provides functions to validate Placekey formats, estimate distances based on shared prefixes lengths, and access Placekey's free datasets stored in S3. Additionally, it includes a rate-limited client for the Placekey API, allowing users to look up Placekeys for locations using geographic coordinates or address details. The library can be installed from PyPI and requires geos on MacOS Big Sur for its shapely dependency.
