Pricing
The determination is the cheap part. What you pay for is doing it at catalogue scale, and being able to prove afterwards which ruleset produced it.

How metering works
One classification is one unit, whether it arrives through /api/classify, as an item inside a batch call, or as part of an automatic re-check when the ruleset changes. Pro includes 2,000 units a month; above that, usage is metered at $0.02 a unit and never blocked — a hard stop in the middle of a catalogue import is worse for you than an overage line is.
The free tier is one classification per rolling day, rate limited, with no account required. It is a real classification, not a preview: the same engine, the same ruleset hash, the same citations.
