FAQ

Why does my query return 403?

You need to put your API key in the x-api-key request header.
How can I tell which models are used to generate a response?

Set explain to true.
Do I really need all these request parameters?

No, probably not. The interactive API reference sometimes adds example values for many unnecessary parameters, particularly for POST requests. For typical point-time queries, you only need to specify the points and variables you want and either the times you want or enough time parameters to calculate them. Take a look at our examples.
Why is my query returning null data?

There are a variety of possible reasons for this, see data troubleshooting.
How does FILL differ from GAP?

GAP means no models were selected to supply data for a time-point. FILL means a model was selected and used to supply data for a time-point, but the model only contained placeholders there. This may often occur around the edges of a model domain.
