Libris Developer

Welcome developers!

We created the Libris API to enable developers to create fantastic applications that integrate Libris's powerful features. Here, you’ll find helpful documentation to get you started using the API.


The latest version of the Libris API is located at /psapi/v3 and can be accessed at as well as at a user subdomain or CNAME. Requests to all endpoints require an API key. Some endpoints (known as member endpoints) require user authentication, while others (public endpoints) do not as they are read-only. The Libris API supports cross-origin resource sharing (CORS) so that you can interact with our API from a client-side web application.

Responses can be returned in JSON (default) or XML format. JSONP is supported.

To get started:

  1. Register for an API Key
  2. Dive into the Documentation or Jump to Our Quick-Start Guides
