List models

The models your key can call, in OpenRouter's shape. Prices are decimal strings in US dollars per token. An audio model's prompt price is per second of audio or per character of input; an image model lists its output price in image_output, and a model priced per image adds image_token. With a key, a model carries reasoning_efforts where its provider lists them. A speech-to-text model carries verbose_json, and a text-to-speech model supported_voices, default_voice and speech_speed. Without an Authorization header it lists the public models, priced at each model's first-ranked public provider.
