637637The Go SDK supports the following platforms:
638638 
639* **Agent Platform:** `import "github.com/anthropics/anthropic-sdk-go/v2/vertex"`. Use `vertex.WithGoogleAuth(ctx, region, projectID)` or `vertex.WithCredentials(ctx, region, projectID, creds)`.
639* **Claude Models on Google Cloud (Google managed):** `import "github.com/anthropics/anthropic-sdk-go/v2/vertex"`. Use `vertex.WithGoogleAuth(ctx, region, projectID)` or `vertex.WithCredentials(ctx, region, projectID, creds)`.
640640* **Bedrock:** `import "github.com/anthropics/anthropic-sdk-go/v2/bedrock"`. Use `bedrock.NewMantleClient` for the Messages-API Bedrock endpoint (streams over SSE), or `bedrock.WithLoadDefaultConfig(ctx)` / `bedrock.WithConfig(cfg)` (`bedrock-runtime` path). Importing the `bedrock` package globally registers a decoder for `application/vnd.amazon.eventstream` with the SDK's streaming layer (through package `init()`). This applies whether you use the `bedrock-runtime` `WithConfig`/`WithLoadDefaultConfig` path or `NewMantleClient`.
641641* **Claude Platform on AWS:** `import anthropicaws "github.com/anthropics/anthropic-sdk-go/v2/aws"`. Use `anthropicaws.NewClient(ctx, cfg)` with an `anthropicaws.ClientConfig` value to construct a client; set `WorkspaceID` on the config or the `ANTHROPIC_AWS_WORKSPACE_ID` environment variable. The `anthropicaws` import alias avoids a name collision with `github.com/aws/aws-sdk-go-v2/aws` when both are imported. Available in beta.
642642* **Foundry:** `import "github.com/anthropics/anthropic-sdk-go/v2/foundry"`. Use `foundry.NewClient(cfg)` with a `foundry.ClientConfig` value to construct a client; set `APIKey` (or `AzureADTokenProvider` for Microsoft Entra ID) and `Resource` on the config, or the `ANTHROPIC_FOUNDRY_API_KEY` and `ANTHROPIC_FOUNDRY_RESOURCE` environment variables.
