Anything that lets you set a custom API base URL can talk to OrcaRouter. This section is a copy-paste setup for popular finished tools — CLI coding agents, general agents, and desktop clients. For wiring OrcaRouter into your own code with an SDK (LangChain, Vercel AI SDK, …), see Frameworks & Integrations instead.

​
Two rules that apply to every tool

1. Model names use the vendor/model format — e.g. anthropic/claude-opus-4.8, google/gemini-2.5-flash. The simplest choice is orcarouter/auto, which lets OrcaRouter pick a live model for you. List everything available with:
curl https://api.orcarouter.ai/v1/models -H "Authorization: Bearer sk-orca-..."
2. Whether the base URL keeps /v1 depends on the protocol:
  • OpenAI-compatible tools → https://api.orcarouter.ai/v1 (with /v1).
  • Anthropic-protocol tools (Claude Code, Copilot CLI) → https://api.orcarouter.ai (no /v1 — the tool appends /v1/messages itself).
Each tool’s page tells you which one it needs.
Create an API key on the API Keys page of the OrcaRouter console; keys start with sk-orca-.
