Constants

ANTHROPIC_PREFIX = "anthropic/"

OpenRouter model ids for Anthropic models all carry this prefix, and it is the whole capability test — no metadata call, no model table.

DEFAULT_APP_NAME = "smith"

DEFAULT_ENDPOINT = "https://openrouter.ai/api/v1/chat/completions"

DEFAULT_SITE_URL = "https://github.com/webmatze/smith"

Constructors

new(api_key : String = ENV.fetch("OPENROUTER_API_KEY", ""), default_model : String = "qwen/qwen3.8-max", timeouts : Timeouts = Timeouts.default, cache : Bool = true)

Instance methods

api_key

cache?

Prompt caching, and only reachable on an anthropic/ route. On by default like the direct Anthropic provider: on any other route the markers are a verified no-op — OpenRouter answers 200 and ignores them — so leaving it on costs nothing.

complete(request : Request) : Response

complete_streaming(request : Request, &on_delta : String -> Nil) : Response

Streaming entry point. The default does no streaming at all — it runs complete() and hands the text over in one piece.

That default is what makes deltas universal: callers always see them, whether or not the provider streams, so neither the agent loop nor the renderers need a special case. Providers override this; when streaming is switched off they call super.
