Your AI CLI,
as an OpenAI API

Bridge Claude Code, Gemini, Codex, or GitHub Copilot into any app that speaks the OpenAI format. No API keys. No extra billing.

$ npm install -g bridgerapi

Then run bridgerapi for the interactive setup wizard

How it works

One bridge, any backend

bridgerapi runs locally and translates between the OpenAI API format and whichever CLI you have logged in.

Your app
Goose, Cursor, Open WebUI… → POST /v1/chat/completions
to http://127.0.0.1:8082

bridgerapi
local HTTP server ↕ Converts messages → prompt
Routes by model prefix

CLI subprocess
claude / gemini / codex / gh → Uses your existing OAuth session
Streams output back as SSE

Setup

One command to get started

Run bridgerapi and the wizard handles everything.
