# How Bindings Work

The language bindings in `ant-sdk` are clients for the `antd` daemon. They share the same daemon surface, but they do not expose identical constructors, transports, or helper APIs.

## Architecture

Each binding translates language-native inputs into requests to `antd`, then maps daemon responses back into that language's models and errors.

The pattern is:

1. your application talks to a language client
2. the language client talks to `antd`
3. `antd` talks to the Autonomi network through `ant-core`

## Defaults

The daemon defaults are:

* REST: `http://localhost:8082`
* gRPC: `localhost:50051`

Bindings usually default to those same endpoints when you do not supply an override.

## Transport Split

* JavaScript and TypeScript are documented as REST-based
* Python, Go, and Rust document both REST and gRPC support
* other bindings vary by package and docs coverage

Check the individual page before assuming a transport is available in your language.

## Discovery helpers

Several bindings include daemon discovery helpers based on the `daemon.port` file written by `antd` on startup.

Examples from the current packages:

* JavaScript: `RestClient.autoDiscover()`
* Python: `discover_daemon_url()` and `discover_grpc_target()`
* Go: `NewClientAutoDiscover()`
* Rust: `discover_daemon_url()` and `discover_grpc_target()`

Some bindings use discovery only through explicit helper APIs rather than by default constructors.

## Naming Differences

The bindings use different entry points:

| Language   | Current entry point                                               |
| ---------- | ----------------------------------------------------------------- |
| JavaScript | `createClient()` or `new RestClient(...)`                         |
| TypeScript | `createClient()` with exported types from the same `antd` package |
| Python     | `AntdClient()` / `AsyncAntdClient()`                              |
| Go         | `NewClient(...)`                                                  |
| Rust       | `Client::new(...)` from the `antd-client` crate                   |

Use the package-specific page when you need exact constructors, install commands, or transport notes.
