The service supports the MDQ protocol, which enables you to look up individual entity's metadata using its entity ID. To query, connect to the MDQ location with the following query string syntax:

https://mdq.incommon.org/entities/<$entityID>

where <$entityID> is the URL-encoded string of the entity ID you are searching. If you are searching for entity ID: https://acme.org/idp, the web query would be:

https://mdq.incommon.org/entities/https%3A%2F%2Facme.org%2Fidp
