Questions

What counts as processed data?

Every request and response you send to three.dev, added up over the month. A request of 5,000 tokens is about 20 KB, so 100,000 of those requests (500 million tokens) is about 2 GB.

What counts as a scored request?

A request that three.dev scores. Your sampling rate sets how many requests get scored, and you can add a daily cap.

What happens when I reach a limit on Free?

You pay nothing. To send more data or score more requests, upgrade to Starter.

Do you charge per seat?

No. Every plan includes unlimited seats, so the whole team can see the failures.
