STORM API Billing Policy Guide#
STORM APIs use a credit-based billing system.Credits are deducted based on the volume of documents processed, allowing you to pay only for what you actually use.
1. Credit-to-Document Conversion Ratio#
10 Credits = 1 Page Conversion Example: Converting a 100-page document requires 1,000 credits.
XLS / XLSX / CSV Processing Standards
Unlike plain text documents, spreadsheets require a cell-based data structure analysis. Therefore, a different page calculation method applies:
1 Sheet is counted as 1 Page.
If a single sheet exceeds 4,000 characters, every additional 4,000 characters is counted as 1 additional page.
Example: A single sheet containing 5,000 characters → Calculated as 2 pages → 20 credits required.
Conversion includes all processes such as OCR, image recognition, and structural parsing.
