APIs not returning datasources?

I need to fetch the Fuel Id from the datasources to call the Fuel API. I have tried geocode and poiSearch from my code, and on the API Explorer page, but no datasources are returned. The documentation shows them as part of the results[] response. No Love for me.

Any hints?

You need to have signed contract to use this feature.

So, Fuel API is useless without subscription…

Actually you need a signed contract for Fuel Prices API. And as a result Search API is also not returning those IDs if you can’t use them.
