Pricing
Pay for checks, not seats.
1,000 free credits every month. After that, prepaid packs that never expire. No subscription, no minimum, no sales call.
Simple per-check pricing.
You're charged only when a check returns a result. Errors, invalid requests and rate-limited calls are free.

Billing, plainly.
Do credits expire?
Prepaid credits never expire. The free monthly credits reset on the first of each month (UTC).
Is there a subscription?
No. You buy credit packs when you need them. Turn on auto top-up if you'd like us to refill automatically when your balance runs low.
What happens when I run out?
API calls return HTTP 402 with a clear message until you add credits. Nothing is charged by surprise.
Can I get a refund?
Unused prepaid credits can be refunded within 30 days of purchase. Email support and we'll sort it out.
Do you charge for failed requests?
No. Invalid requests, rate-limited calls and server errors cost nothing. A check that returns a result is charged, even if the answer is 'invalid email'.
