TypeScript providers
Providers contracts and source references for TypeScript.
ProviderRegistry and registerAnthropicModel, registerOpenAiModel, and registerGoogleModel are exported from core. Registration uses explicit model IDs and installation options. There is no aggregate Anthropic constructor. Keep credentials in the server process; browser delivery requires a separate trusted service.
TypeScript reference
Each reference records the source path, hash and declaration inventory for this language. Start at the import boundary before using a symbol found in a deeper implementation file.
Endpoint and model configuration
Read the provider's current catalog and select a model ID available to your account. Adapters may have configurable default endpoints. No model name in a source fixture is a promise of current provider availability. Test streaming, structured output, tool calls and cancellation separately for the selected provider.
