# AI Text Content Classification API

## About

This Utility API focuses on AI-based Content Classification, analyzing text and providing accurate categorization in textual content.

This API identifies relevant content categories within a document. The API filters and returns the most specific category for precision, enhancing applications in search, data organization, and content recommendations.

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:

| Provider (requested_service) | Atoms |
| --- | --- |
| Google | 500 |

## 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.
