megapt

HTTP service that returns an active ChatGPT access token.

The service can:

• restore/refresh a saved token from /data
• auto-register a new ChatGPT account when needed
• get verification email from a disposable mail provider (temp-mail.org)
• expose token and usage info via HTTP endpoint

Endpoints

• GET /token - legacy route (defaults to chatgpt provider)
• GET /chatgpt/token - explicit provider route

Example response:

{
  "token": "<access_token>",
  "limit": {
    "used_percent": 0,
    "remaining_percent": 100,
    "exhausted": false,
    "needs_refresh": false
  },
  "usage": {
    "primary_window": {
      "used_percent": 0,
      "limit_window_seconds": 604800,
      "reset_after_seconds": 604800,
      "reset_at": 1772987784
    },
    "secondary_window": null
  }
}

Environment variables

See .env.example.

• PORT - HTTP port for the service
• USAGE_REFRESH_THRESHOLD - percent threshold to trigger background token rotation
• DATA_DIR - directory for persistent data (chatgpt_tokens.json, screenshots, etc.)

Local run

Requirements:

• Python 3.14+
• Playwright Chromium dependencies

Install and run:

uv sync --frozen --no-dev
./.venv/bin/python -m playwright install --with-deps chromium
PYTHONPATH=./src ./.venv/bin/python src/server.py

Then request token:

curl http://127.0.0.1:8080/chatgpt/token

Docker deployment

Build image:

docker build -t megapt:latest .

Run container:

docker run -d \
  --name megapt \
  --restart unless-stopped \
  --env-file .env \
  -v ./data:/data \
  -p 80:80 \
  megapt:latest

Check logs:

docker logs -f megapt

Notes

• Service performs a startup token check and tries to recover token automatically.
• Token write path is synchronized (single-writer lock) to avoid parallel re-registration.
• Browser runs in virtual display (Xvfb) inside container.
• Keep /data persistent between restarts.
