How does API pricing work?

All of our APIs are on a cumulative volume-based pricing model. Quite simply, the more queries you run in a given month, the cheaper it gets per query. We have Online Pricing Calculators you can utilize to estimate monthly costs based upon your anticipated volume. All of our APIs are set up to be pay-per-use.

You pay for the API queries via the prepaid balance on your account. After you register your free account, you can use the payment method of your choice (we accept all major credit cards, PayPal, Venmo, Apple Pay, and Google Pay) to load your account with a prepaid balance. As you run your API queries we slowly chip away at that balance. When the balance gets low, it will automatically replenish to ensure there are no service interruptions.

Aside from that, there are no additional charges. No sign up fees, membership fees, subscription fees, etc.
