An R interface to German government and public sector APIs listed on bund.dev. 34 ready-to-use adapters return tidy tibbles for immediate use in dplyr/ggplot2 workflows.

Three-layer architecture

Layer	What it does	Entry point
Registry	Browse and search all APIs on bund.dev	`bunddev_list()`, `bunddev_info()`
OpenAPI core	Explore specs and call any endpoint	`bunddev_spec()`, `bunddev_call()`
Adapters	Ready-made functions returning tidy tibbles	e.g. `smard_timeseries()`, `autobahn_roadworks()`

Adapters include built-in response caching and rate limiting.
