# API [Home](/rezoom-sql/master.md) > API [← What's missing?](/rezoom-sql/language/missingfeatures.md) | [Rezoom.SQL →](/rezoom-sql/api/rezoomsql.md) ## API This section covers the F# API to Rezoom.SQL. Because most of the complexity is contained in the SQL language, the public API is rather small. The API surface intended for public use is in the following namespaces: * Rezoom.SQL: type providers. * Rezoom.SQL.Migrations: migration configuration and utilities. * Rezoom.SQL.Synchronous: extension methods for running provided SQL commands synchronously * Rezoom.SQL.Asynchronous: extension methods for running provided SQL commands asynchronously * Rezoom.SQL.Plans: extension methods for running provided SQL commands as Rezoom `Plan`s. The following namespaces also contain many members that are technically public, but are *unstable and undocumented* as they are intended for internal use. These are public in part due to technical limitations, and in part because I think you should be able to use the code as long as you accept that you're coloring outside the lines and minor version releases may break the API. * Rezoom.SQL.Compiler: implementation of the RZSQL language, typechecker, backends. * Rezoom.SQL.Mapping: code used at runtime by RZSQL provided types, primarily for deserializing objects from SQL result sets. *** [← What's missing?](/rezoom-sql/language/missingfeatures.md) | [Rezoom.SQL →](/rezoom-sql/api/rezoomsql.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://humbobst.gitbook.io/rezoom-sql/api.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
