How pricing works

Each endpoint below shows its billing unit. Search and conversation requests combine a base price with a per-result rate. Document text is billed by returned tokens, while originals and recognition are billed per document. Search feedback, comments, votes and document activity are not billed.

For example, if the base price is $0.01, the multiplier is $0.001, and you set a limit of 10, the total cost for that call would be $0.01 + ($0.001 × 10) = $0.02.

You can optimize costs by choosing the limit parameter to match your needs — higher limits return more results at a higher cost per call.
