00 · Evaluate

Test the real build first.

An evaluation license puts a full current build in your hands — every row, every column, no sampling — so you can measure it against your own traffic before anyone talks about terms.

01 · License

Then license what you use.

Standard, for detection and decisions inside your own product and operations.
Redistribution, when the data ships onward inside what you sell — priced by scope, not by seat.
Annual terms, a named contact, and flexible payment terms — monthly, quarterly or yearly.
