chatgpt-relay-server

See the blog post for more information!

ChatGPT doesn't have an official API yet, so this is a simple REST API server that proxies messages to a ChatGPT session running in a Puppeteer-controlled browser instance (by way of the chatgpt package). For ease of experimentation, the REST API server is CORS-enabled, and will respond to requests from any origin, without authentication.

Use at your own risk! I'm not responsible if this gets your account banned!

Usage

Google Chrome must be installed on your system, as required by the chatgpt package.

chatgpt-relay-server accepts configuration via environment variables:

• OPENAI_EMAIL: Email address to auto-populate into the login form. If not supplied via environment variable, will be prompted for interactively.
• OPENAI_PASSWORD: Password to auto-populate into the login form. If not supplied via environment variable, will be prompted for interactively.
• OPENAI_IS_GOOGLE_LOGIN: Whether this is a Google account or an OpenAI account. Accepts anything truthy (true, 1, ...) or falsey (false, 0, ...) when parsed as JSON. If not supplied via environment variable, will be prompted for interactively.
• CHATGPT_RELAY_SERVER_HOST: Host for the REST API server to bind to. Default: 127.0.0.1
• CHATGPT_RELAY_SERVER_PORT: Host for the REST API server to bind to. Default: 3000

You can also supply additional environment variables containing tokens for CAPTCHA-bypassing services, as described in the documentation for the chatgpt package.

When running the server on the command line, it will first prompt you interactively for any configuration without a default not supplied via environment variables, and will then start up a browser instance and attempt to log into ChatGPT. You may have to complete one or more CAPTCHAs. On successful login, the REST API server will launch and start serving requests.
