Questions about this capability

What does a verified keyword volume result cost?

DataForSEO is the lowest at $0.0016 per verified result once misses and wrong answers are counted. Its list price is $0.0015 per call.

What counts as a hit for keyword volume?

A volume figure for the keyword. Fill rate is the share of calls that produced a hit. Per-hit endpoints bill only hits, and failed calls are never billed.

Can I use my own provider key?

Yes for DataForSEO. Calls on your own key are routed and scored like any other, and never metered.
