Search API Basics#
Building a Search API query consists of 3 basic steps:
- Use the Search API base URL: https://api.daac.asf.alaska.edu
- Pick an endpoint. All available endpoints are listed in the Keywords documentation. The Search endpoint uses this base URL: https://api.daac.asf.alaska.edu/services/search/param
- Build your query using keywords
The completed URL will be in this format: https://api.daac.asf.alaska.edu/services/search/param?keyword1=value1&keyword2=value2,value3&keyword3=value4-6
Once your query is built, you may execute by copy/pasting into a browser window, a command line interface, or by using a program. More details on various options and some syntax tips can be found in the Search API Tools documentation.
