Python SDK · recommended

Typed, relational, agent-ready

A generated client with real types, enums, and the links between objects — the structure a flat JSON response can't carry. Autocompletes in your editor and reads cleanly to coding agents.

Fully typed · autocompletes
Objects link to objects
Typed errors & pagination

Typed Python client. Set up the SDK in your uv project, then pull this API’s typed client:

uv add parse-sdk
uv run parse init
uv run parse add --marketplace gkd-bayern-de-api

uv run parse add --marketplace pulls a pinned snapshot of this canonical API — it won’t change underneath you. To customize it, subscribe and swap to your own copy.

About the Bayern API

The Bayern API on Parse exposes 3 endpoints for the publicly available data on gkd.bayern.de. Calls return JSON over HTTPS and are billed per successful response.

Pin a release with the API-Snapshot-Version header so canonical updates don't silently change your contract.
