The actor uses pay-per-event pricing with one number_checked event per checked number.

Current planned rates per 1,000 checked numbers:

Plan	Price per 1,000
No subscription / Bronze	$20.00 / $17.00
Silver	$14.00
Gold and above	$12.00

Duplicates are removed before checking, so you pay for unique numbers checked.

Notes

• unknown means the registration status could not be determined for that number; it still counts as a checked number.
• Uploaded CSV/XLSX files can use common phone columns such as phone, mobile, or telephone.
• onlyRegisteredNumbers filters output rows, but billing still applies to every checked number.
