Client APIs
Overview
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](#docs:api:c:connect) to get started, or check out the [Full API overview](#docs:api:c:api).  
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`](https://github.com/duckdb/duckdb/tree/main/tools/sqlite3_api_wrapper) folder in our source repository for more information.
