Getting started

OpusGate is a single API endpoint that gives you Claude and GPT models at ~3× lower price than the official APIs. The protocol is Anthropic/OpenAI-compatible, so most existing tools work out of the box.

Three steps

1. Create an account — takes 10 seconds, email + password.
2. Top up your balance (min $5) on the Top up page.
3. Issue an API key on the API keys page and paste it into your tool.

The API is wire-compatible with Anthropic (/v1/messages) and OpenAI (/v1/chat/completions). Pick whichever protocol your tool expects.
