 # Changelog
 
+## 2026-04-28 - 1.1.3 - feat(platformclient)
+Add runtime platform binding configuration.
+
+- Added `SERVEZONE_PLATFORM_URL`, `SERVEZONE_PLATFORM_AUTHORIZATION`, and `SERVEZONE_PLATFORM_TOKEN` support.
+- Added environment binding discovery through `SERVEZONE_PLATFORM_BINDING` and `SERVEZONE_PLATFORM_BINDINGS`.
+- Preserved `SERVEZONE_API_DOMAIN` and `SERVEZONE_PLATFROM_AUTHORIZATION` fallbacks.
+
 ## 2024-10-05 - 1.1.2 - fix(core)
 Fix authorization handling and format code.

 ## Configuration
 
@@ -51,14 +51,25 @@ The client needs two values:
 
 | Value | How to provide it | Notes |
 | --- | --- | --- |
-| Authorization token | Constructor argument, `init()` argument, or `SERVEZONE_PLATFROM_AUTHORIZATION` | The current environment variable name is intentionally documented as implemented. |
+| Authorization token | Constructor argument, `init()` argument, `SERVEZONE_PLATFORM_AUTHORIZATION`, `SERVEZONE_PLATFORM_TOKEN`, binding credential env, or `SERVEZONE_PLATFROM_AUTHORIZATION` | The misspelled legacy env name remains supported for compatibility. |
-| API domain | `SERVEZONE_API_DOMAIN` | Loaded on demand through `@push.rocks/qenv`. |
+| Platform URL | Constructor options, `SERVEZONE_PLATFORM_URL`, binding endpoint, or `SERVEZONE_API_DOMAIN` | Loaded on demand through `@push.rocks/qenv`. |
+| Runtime bindings | Constructor options, `SERVEZONE_PLATFORM_BINDING`, or `SERVEZONE_PLATFORM_BINDINGS` | Values are JSON-encoded `IPlatformBinding` objects from `@serve.zone/interfaces`. |
 
 ```typescript
 const client = new SzPlatformClient();
 await client.init('your-platform-authorization-token');
 ```
 
+Constructor and `init()` also accept options:
+
+```typescript
+const client = new SzPlatformClient({
+  token: process.env.SERVEZONE_PLATFORM_TOKEN,
+  platformUrl: process.env.SERVEZONE_PLATFORM_URL,
+});
+await client.init();
+```
+
 ## Debug Mode
 
 Pass `test` as the authorization string to enable debug mode. In debug mode, the client does not open a TypedSocket connection and connector methods log or return deterministic test values instead of sending real platform requests.
