Antigravity CLI → OpenAI proxy

Local (or VPS) HTTP proxy that turns agy (Antigravity CLI) quota into OpenAI / Anthropic / Gemini endpoints. Multi-account round-robin + egress HTTP proxy pool.

Requires agy.exe (or agy on Linux). Direct Cloud Code HTTP is 403 SUBSCRIPTION_REQUIRED — the backend is always a CLI subprocess.

Endpoints

Path	Notes
POST /v1/chat/completions	OpenAI, stream + non-stream
POST /v1/messages	Anthropic
POST /v1beta/models/{m}:generateContent	Gemini native
GET /v1/models	model list
GET /healthz	liveness
GET /admin/ui	dashboard (loopback open; remote needs API key)

Default listen: 127.0.0.1:1413. Client key: sk-agy-local (change in config.json).

Setup

cp config.json.example config.json
cp accounts.json.example accounts.json
cp proxies.txt.example proxies.txt
# install agy CLI, log in once
npm install
node server.js

Dashboard: http://127.0.0.1:1413/admin/ui

Add accounts in Accounts: Login (link + code) — open the Google URL, paste the oauth-callback?code=... redirect.

Linux login uses the official agy CLI (PTY via script). After Buat link, finish Google login and Simpan within ~50s (CLI timeout). Do not exchange the code yourself; oauth-clients.json secrets are not paired with the CLI client.

Linux token file: ~/.gemini/antigravity-cli/antigravity-oauth-token (per-account HOME / geminiDir).

VPS

export AGY_PROXY_HOST=0.0.0.0
export AGY_PROXY_PORT=1413
export AGY_BIN=/home/ubuntu/.local/bin/agy   # or wherever `agy` is
node server.js

• /v1/* always needs Authorization: Bearer …
• Remote /admin/* needs the same key. Dashboard: http://<ip>:1413/admin/ui?key=sk-agy-local
• Windows: agy spawn is serialized (one Credential Manager target). Linux: isolated HOME per account → parallel.
• Egress check (POST /admin/egress/check) needs undici (npm install).
