Phone Numbers

Search available numbers

Search the provider's inventory for numbers available to purchase in a country (default US). Optional filters narrow the results. The country must be offerable (see GET /v1/phone-numbers/countries). Voice capability is always required; pass sms=true to only see numbers that can also text (SMS support is per-number, not per-country). Numbers a purchase would refuse are left out, and any result's phoneNumber can be bought exactly by passing it to POST /v1/phone-numbers/purchase.

Works without an API key. Keyless calls get up to 12 results with the middle digits masked (maskedNumber), each with a claimId and a claimUrl: a signup link that lands a person on the dashboard's confirm step with that number picked, so an agent can search for a user and hand them one link. Keyless calls are rate limited per IP and results are cached for a few minutes. With an API key you get full numbers and no claim fields.
