There are multiple solutions available to query the EODC metadata repository:

CSW

Our CSW interface can be accessed via https://csw.eodc.eu
Find further information about usage of the CSW interface here.

From Python

If you want to query our metadatadata directly in your python application, we highly recommend using OWSLib.

eomEX

eomEX+ (Earth Observation Metadata Explorer) is a very slim web catalog on top of our CSW Server. It allows querying the EODC data repository trough a simple Web GUI as well as an API.
