Anthropic Provider

Import from @anvia/anthropic.

AnthropicClient

type AnthropicClientOptions = {
  apiKey?: string;
  baseUrl?: string;
  client?: Anthropic;
};

class AnthropicClient {
  readonly client: Anthropic;
  constructor(options?: AnthropicClientOptions);
  listModels(): Promise<ModelList>;
  completionModel(model?: AnthropicCompletionModelName): AnthropicCompletionModel;
}

Purpose: factory for Anthropic completion models and model listing.

Return behavior: completionModel(...) returns a streaming Anvia completion model. listModels() fetches Anthropic’s model list and returns a normalized ModelList.

Notable errors: constructor throws when neither client nor apiKey is supplied; listModels() rejects with ModelListingError when the provider request fails.

Model Name Types

type AnthropicCompletionModelName = ModelId<KnownAnthropicCompletionModelName>;

KnownAnthropicCompletionModelName is the union of known Anthropic completion model IDs used for autocomplete.

Purpose: typed model identifiers for autocomplete while preserving support for custom strings.

AnthropicCompletionModel

class AnthropicCompletionModel implements StreamingCompletionModel {
  constructor(client: Anthropic, defaultModel?: AnthropicCompletionModelName);
  completion(request: CompletionRequest): Promise<CompletionResponse>;
  streamCompletion(request: CompletionRequest): AsyncIterable<CompletionStreamEvent>;
}

Purpose: adapter for Anthropic Messages API.

Return behavior: maps Anvia completion requests to Anthropic params and returns normalized responses/events.

Notable errors: rejects or yields SDK/provider errors.

Helper Namespaces

namespace anthropic {
  AnthropicClient;
  AnthropicCompletionModel;
}

Purpose: namespaced access to the same public model/client exports.

Return behavior: export namespaces only.

Notable errors: none directly.
