OAuth, device flow, and an API key. That is the entire setup — no credit card, no configuration files, no migrations.
01
Sign in with GitHub
OAuth authenticates your account. No separate signup, no password.
02
Authorize Copilot
Device flow links your GitHub Copilot subscription. Validated instantly.
03
Point any agent
Copy the API key into Claude Code, Codex, Cursor. You're live.
A real gateway — not a wrapper.
OpenAI-compatible
Chat completions, responses, and messages — the exact protocol your existing clients already speak.
Streaming first
Server-sent events preserved end-to-end. No buffering, no broken token streams, no latency tax.
Zero config on the agent
Point any OpenAI- or Anthropic-compatible client at our base URL. The key is all that changes.
Model discovery
GET /v1/models returns the live catalog your Copilot plan has access to, cached and always fresh.
Works with every coding agent.
Already compatible. Copy, paste, and keep shipping.
