ORCA API

ORCA API returns all OpenRouter models with their available endpoints. The same model can vary significantly depending on which provider serves your request. Pricing, context length, and capabilities are exposed at the endpoint level.

Data not available in the standard OpenRouter API is included: long context pricing tiers, data retention policies, hidden usage limits, moderation requirements, completions vs chat completions support, provider ids with variant tags, and configuration details for reasoning, caching, and web search.

This is a public preview, and the schema will evolve with feedback and feature updates. Major changes are versioned, and preview versions will be maintained for an extended period of time, so you can confidently use it in your projects.
