About

This Utility API focuses on AI-based invoice data extraction, concentrating on identifying key information within documents of invoices, utility bills, and purchase orders.
This API can extract fields and line items from documents of various formats and quality, including phone-captured images, scanned documents, and digital PDFs. The API analyzes invoice text, extracting crucial details like customer name, billing address, due date, and amount due, returning a structured JSON data representation and can be really useful for automating invoice processing, reducing manual data entry, and enhancing accuracy in financial workflows.
The atoms cost is subjected to change depending on the size of the input file and the provider selected. The list of providers and the atoms cost for each provider is given below:

Note: In order to test the API on API Playground, just click on "Show optional inputs" and enter the Authentication token for the provider before clicking on Send request. The output response structure and the result of the AI utility APIs depend on the service provider and it may vary depending on which service provider is selected.

Authentication

All API requests to ApyHub services need to be authenticated. Currently we support tokens or basic authentication mechanisms. You can generate and view your existing credentials from your workspace settings (on the left side of the navbar) and go to “API Keys".
Points to note:
  • Credential secrets are generated on the fly and are not stored in plain text, so on generating a credential please save the secrets somewhere safe.
  • Use the apy-token as the header parameter to pass the token.
  • Use the Authorization header to send the basic authentication credentials.
