# Get Contact Capabilities

`GET /v1/contacts/capabilities`

Check which messaging channels a phone number supports, without sending
a message.

Runs a live check (typically 1-2 seconds), so the result reflects the
number right now. Capabilities can still change by the time you send.
Requires at least one active iMessage-capable number on the account.

## Query parameters

- `phone_number` string, required — Phone number to check (E.164 preferred; URL-encode + as %2B)

    - `imessage` boolean, required
    - `sms` boolean, required
