Order a Caviar number from code

The SMS verification API takes the same order with the service slug caviar.

curl -X POST https://smstogo.net/api/v1/orders \
  -H 'Authorization: Bearer sk_...' \
  -H 'Content-Type: application/json' \
  -d '{"country_code":"us","service_slug":"caviar"}'
§ FAQ

Caviar verification questions

Can I receive Caviar SMS verification codes online?

Yes. Order a Caviar number, enter it on Caviar, and the verification code appears in your SMSToGo dashboard or through the API as soon as the text arrives.

How much does a Caviar verification number cost?

$0.31 per number, charged from your prepaid wallet when you order. There is no subscription.

What if Caviar never sends the code?

The order ends without a message and the full $0.31 goes back to your wallet automatically. Caviar may refuse numbers it recognizes as virtual, so you only pay for numbers that actually receive a code.

Can I use the same number for Caviar again later?

No. Each number is one-time: it receives the code for a single order and is then released, so it cannot be used to recover the Caviar account later.
