DuckDB implements a custom C API modelled somewhat following the SQLite C API. The API is contained in the duckdb.h header. Continue to Startup & Shutdown to get started, or check out the Full API overview.

We also provide a SQLite API wrapper which means that if your applications is programmed against the SQLite C API, you can re-link to DuckDB and it should continue working. See the sqlite_api_wrapper folder in our source repository for more information.

Installation

The DuckDB C API can be installed as part of the libduckdb packages. Please see the installation page for details.
