What is free, what costs extra
Free access and trial
Free tier: 100 certified runs per month.
Extra costs and taxes
Hard caps, no overage billing.
Costs that are easy to miss
- Hard caps with no overage billing: when you reach the monthly run limit, runs stop rather than bill extra.
- Quotas are enforced per account and shared across API keys, not per key.
- Using it means integrating the SDK or CLI into your own code, which costs engineering time.
- Enterprise pricing is contract-based and requires a sales call.
