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.
