Optimal API

One API key for every major model.

A prepaid, OpenAI-compatible API for high-usage commercial teams and enterprises. Call the models you already use, route a request to a model that can do the job for less, and keep serving when a provider slows down.

One key, one endpoint

gpt-4o-mini, Claude Haiku, Grok, DeepSeek, and Qwen are on the same chat API. Your application keeps an OpenAI-style base URL.

Spend on the tokens you need

Auto profiles can choose a capable model instead of sending every call to the highest price. Token-saving controls are available when an organisation turns them on. Published savings stay blank until the platform has measured them.

Stay up when a model lags

The gateway watches latency. A slow model is moved down the list, and a request that receives no first byte can continue on the next capable model. The balance is charged for the model that answered.

How billing works

Prepaid. Input and output are separate.

01

Add balance

Top up from 1.00 to 10000.00 in the account unit, with at most two decimal places.

02

Call the API

A request reserves a hold, then settles the tokens the provider actually used. Charges round up.

03

Read the result

The portal shows balance, held amount, usage, and measured savings when there is data to show.

Payments

Alipay, WeChat Pay, and crypto.

Every account can start a top-up with Alipay, WeChat Pay, USDT, or USDC. The balance moves after the payment is verified.
