# API Documentation

{% hint style="info" %}
**Note:** The Search APIs are currently in private testing and are not yet publicly available. If you are interested in additional information, please contact your Pex representative.
{% endhint %}

### Overview

These endpoints provide REST access to Search workflows.

The API supports two ways to perform a search:

1. **Use Case Search:** the client provides a predefined use case (e.g. "identify music" or "find song usage") and the API handles the underlying Search configuration.
2. **Advanced Search:** the client explicitly provides fingerprint type and search type for more granular control and custom workflows.

Most search workflows are asynchronous:

1. The client starts a search (using either Use Case Search or Advanced Search)
2. The API returns a `lookup_id`.
3. The client requests the search result of that `lookup_id`.
4. The check endpoint blocks until the completed search response is available.
