What is a credit?
A credit is the unit of consumption for every API call. Each endpoint has a fixed credit cost based on the lookups performed. A failed validation still costs the same as a successful one — the lookup was performed regardless.Credit costs per endpoint
Bundle endpoints — dynamic billing
Bundle endpoints are priced dynamically based on which optional fields you include. You are only charged for the sub-lookups actually performed./v1/deliverability
Maximum: 3 credits. Providing only
email costs 1 credit.
/v1/contact-intel
Maximum: 4 credits. Calling all four data points individually would cost 6 credits — the bundle saves 2 credits on a full call.
/v1/fraud-signals
Maximum: 4 credits.
Monthly allowance
Credits are allocated at the start of each billing cycle and reset monthly. They do not roll over.Checking your balance
Your remaining credit balance is visible in the dashboard. Each API response also includes acredits_used field showing the cost of that specific call.
Running out of credits
When your credit balance reaches zero, subsequent API calls return a402 Payment Required response. You can:
- Upgrade your plan — for a higher monthly allowance
- Purchase a credit add-on pack — one-off top-up that doesn’t affect your billing cycle
Add-on credits are available from the billing page and never expire.
