Frequently asked questions
What counts as a call?
Generating an output counts as one call, and each judge check answered counts as one more. A run of 10 examples with 3 judge checks uses 40 calls. Checks answered by code add nothing. A call that returns an unusable answer still counts.
Do I need my own Anthropic API key?
No. Model usage is included in your plan. Calls are capped per month to keep that sustainable.
What happens when I hit my monthly cap?
Runs pause until the next calendar month, or you can upgrade for a bigger allowance. Nothing is deleted; your prompts, versions, and history stay put.
Can I cancel anytime?
Yes. Manage or cancel from the billing page in one click. You keep paid features until the end of the billing period, then drop to the Free plan.
