Build Your Query

You can build a simple API query using the tool below: Enter query terms, and select the fields you would like to return. The corresponding "request object", will be shown on the left, and the resulting output from the API and the right. You can also use the Open Collections Advanced Search Tool to generate more complex, filtered queries.

Request object:


To return results from the API, send the "request object" in an HTTP POST request to the following URL with your API key.

Tip: Use tools such as the Postman Google Chrome App to test and preview HTTP POST requests.

To harness the full power of the API, see the API Documentation for a full list of supported query types and available fields.
