Guide
Point a client at corouter
All three clients need two facts: base URL https://api.corouter.co, and a model ID from the rate card.
Cursor
Set the base URL to https://api.corouter.co and the model to the ID you want, such as gpt-6-astra or claude-opus-5-5. Other toggles follow your Cursor build.
Codex
Coding IDs include gpt-5.3-codex, gpt-5.2-codex, and codex-auto-review. If the client only accepts a built-in list, follow that list.
Claude Code
Set the model to a Claude ID such as claude-opus-5-5 or claude-sonnet-5. The base URL is still https://api.corouter.co.
Questions
- Is corouter affiliated with OpenAI or Anthropic?
- No. Vendor names identify the model and the published list rate.
