Billing

Unit: per_search · unmatched results billed: no
Priced per search plus a small per-row amount, scaling with limit (default 10). The provider counts the domain itself as one row, so a search is limit + 1 rows.

The exact quote is returned by /v1/inspect before every call and held with headroom on execution. The quote is the price floor: if the provider's actual cost overruns it, the run bills the overrun at the same rate, never above the hold. The unused part of every hold is released.
