You pay based on usage, measured in Units. There are no fixed tiers or committed quantities. Each API call consumes Units, so your cost scales with how many phone number checks you run. A single call can bundle multiple insights, such as format validation and SIM Swap detection, together. This means your spend rises or falls directly with your call volume and the insights you request. Billing is metered against actual API activity rather than a flat subscription.
Top-of-mind questions for buyers
What counts as one billable Unit when I call the Identity Insights API?
A Unit maps to the insights you request in an API call. Each call can bundle insights like format validation, SIM Swap detection, or subscriber match. The insights you include drive Unit consumption, so requesting more insights per call consumes more Units than a single-insight request.
Does testing in the Playground environment consume the same Units as production calls?
The API offers a Playground with a Virtual Operator that returns simulated responses for allowlisted numbers. Production returns live data from mobile operators and needs operator approval. The pricing table meters usage of the APIs; for how each environment affects billed Units, contact the vendor.
How does my cost change if I add more insights to a single request?
You can combine insights in one call, such as Format plus SIM Swap. Each added insight increases what that call consumes. Cost scales with both call volume and the number of insights per call, since billing meters actual API activity rather than charging a flat rate.
