Pricing
Simple, transparent, and affordable legal AI APIs
Isaacus legal APIs have no upfront costs and no hidden fees. You pay only for what you use.
This page provides an overview of the pricing for each of our APIs. All amounts are in USD.
These prices may change in the future but we will always notify you before new pricing goes into effect.
These prices do not include any taxes that we may be required to collect by law in your particular jurisdiction — such taxes will be applied automatically to your invoices.
Those looking for on-premises deployments or a volume discount or to negotiate an alternative pricing model should contact us.
Universal classification
Usage of our universal classifiers is charged solely based on the number of tokens inputted into them.
Note that the number of tokens that get inputted into a universal classifier may differ from the number of tokens inputted into an API endpoint, for example, due to the addition of boilerplate tokens, as explained in our costs page.
This table shows the price per token for each of our universal classifiers:
| Model | Price per token | Description |
|---|---|---|
| Kanon Universal Classifier | per million tokens / per token | Isaacus’ flagship universal classification model, currently ranking as the world’s most accurate universal legal classifier. |
| Kanon Universal Classifier Mini | per million tokens / per token | A more lightweight variant of the Kanon Universal Classifier, optimized for speed and cost-efficiency. |
