Get the current wallet balance for the authenticated account.

get_pricing

Get the retail price per OTP activation for a service in a country. Omit `service` to list prices for every available service.

get_inventory

Get how many numbers are in stock for a service in a country. Omit `service` to list stock for every available service.

create_otp_order

Buy a number to receive an OTP: allocates a number, debits the wallet, and returns an orderId + phoneNumber. Then poll with poll_sms. If no code arrives, do NOT cancel to retry: simply call create_otp…

poll_sms

Check for the SMS / OTP code on an order. Returns the code once it has arrived, otherwise an empty result: poll again after a few seconds. If nothing lands after a minute or two, the fastest path is t…

list_active_orders

List recent OTP orders for the account (awaiting a code or already received).

get_rental_offers

List the rental periods and prices for a country (1 day to 12 months). A rented number is yours for the whole period and receives every SMS sent to it, unlike an OTP order, which is for one code. Omit…

rent_number

Rent a phone number in a country for a period (get the periods and prices from get_rental_offers first). Debits the wallet and returns the number and when the rental ends. Read its SMS with read_renta…

list_rentals

List the account's rented numbers with their country, period and end date. Ended rentals are left out unless `includeEnded` is true.

read_rental_sms

Read the SMS a rented number has received during this rental, newest first. Poll again every few seconds while waiting for a message.

cancel_rental

Cancel a rented number and refund it. Only possible between 5 and 120 minutes after renting, and only if the number has received no SMS; after that the rental runs to its end date.
