# SDK Reference

Find the methods, parameters, return values, and errors for the library or API you are using.

For native libraries that connect directly to the Autonomi Network, use the [native SDK reference](/developers/sdk/reference/native-sdks.md). For web applications, [Browser SDK](/developers/sdk/install/build-in-browser.md) introduces the separate experimental package and links to its API documentation. For client libraries that send requests to a local daemon, a separate background service called [antd](/developers/sdk/install/use-antd.md), use [Language Bindings](/developers/sdk/reference/language-bindings.md). The REST and gRPC references cover that service's APIs.

The APIs are not interchangeable. Each reference describes its own constructors, supported operations, and limits.
