Data Access API#

The SDC provides a REST API that allows users to upload and download files, as well as query for file metadata. The following documentation describes the various endpoints that are supported and how to use them.

The API can be accessed from the following URL: https://api.dev.imap-mission.com

The imap-data-access repository also provides programmatic access and a command-line utility for interacting with the API.
