## One key, many models

A single gateway in front of the models, so your code does not change when the model does.

- **OpenAI-compatible**: Use the official OpenAI SDKs or plain HTTP: just point the base URL at the gateway.
- **One key, one balance**: No separate accounts per provider: one API key and one prepaid balance in the portal.
- **Pay for what you use**: Every request is priced and debited from the balance. No subscription needed.
- **Model catalog**: Choose a model by name from the catalog shown in the portal; prices are on a separate page.
- **Ready for agents**: Works with any client that speaks the OpenAI API, including coding assistants and agent frameworks.
- **Self-service portal**: Keys, balance and connection examples in one place. No tickets, no waiting.
