Everything you need

We handle the model plumbing — sign up, create a token and paste it into your app.

Tutorials

Sign up, create an API token in the console, and paste the address and key into your app.

Transparent pricing

Every model's price and ratio are public, and each request's charge is itemised in your usage logs.

Many models

Covers OpenAI, Claude, Gemini, DeepSeek, Grok, Qwen and other leading vendors.

One address

One address reaches every model — no separate vendor accounts or cards.

Seamless integration

Native OpenAI, Claude and Gemini protocols — existing code only needs a new base URL.

Controlled tokens

Tokens carry quotas, expiry, model scope and IP allowlists, and can be disabled in one click.

Quick start
