# Antigravity OpenAI Proxy

A test-only Hugging Face Space that exposes both:

- `POST /v1/chat/completions` (OpenAI-compatible)
- `POST /v1/messages` (Anthropic-compatible)

The proxy rotates across Antigravity OAuth accounts using the existing hybrid account manager.

## Required Space secrets

- `PROXY_API_KEY`: bearer token required by `/v1/*`
- `CONFIG_ENV`: newline-delimited placeholder-compatible account variables such as `ANTIGRAVITY_1_EMAIL` and `ANTIGRAVITY_1_REFRESH_TOKEN`

Optional variables:

- `FORCE_ENV_ACCOUNTS=true`: make environment accounts authoritative at each cold start
- `ENABLE_WEBUI=false`: disable the browser UI
- `ACCOUNT_STRATEGY=hybrid`: account selection strategy

Never commit OAuth refresh tokens or a real `.env` file.

## Health check

```bash
curl -fsS https://YOUR-SPACE.hf.space/health
```

## OpenAI-compatible request

```bash
curl -sS https://YOUR-SPACE.hf.space/v1/chat/completions \
  -H "Authorization: Bearer YOUR_PROXY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "antigravity/gemini-3-flash",
    "messages": [{"role": "user", "content": "Reply with READY only."}],
    "reasoning_effort": "high"
  }'
```

This Space is for testing only. Antigravity access may be subject to Google terms, quotas, and account enforcement.
