We offer several search filters, such as, region, city, areacode, etc that can help narrow down the search space for a phone number.

curl --request GET \
  --url 'https://api.daily.co/v1/list-available-numbers?region=CA' \
  --header 'Authorization: Bearer $TOKEN'

The response contains numbers that meet the chosen criteria. For simplicty, in the below examples, we will use +19499870006 as an example phone_number.

{
    "total_count": 1,
    "data": [{
        "number": "+19499800001",
        "region": "CA"
    }]
}

To purchase the chosen number, make a POST request to the buy-phone-number and pass the chosen phone number in the data field. See below:

curl --request POST \
  --url 'https://api.daily.co/v1/buy-phone-number' \
  --header 'Authorization: Bearer $TOKEN' \
  --header 'Content-Type: application/json' \
  --data '{
        "number": "+19499800001"
}'

The response returns the phone number and a unique id. The unique id is needed when releasing the chosen phone number, for example.

{
    "id": "5ccc01ca-f448-4f17-b7b4-cf354b7b8256",
    "number": "+19499800001"
}

You can also list all your purchased phone numbers using the following API

curl --request GET \
