# Ensure Carrier

`POST /v1/teams/{team_id}/phone/numbers/carrier`

## Request

- Base URL: `https://api.stormy.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.stormy.ai/v1/teams/{team_id}/phone/numbers/carrier`
- Auth: none declared

Attach this team's own carrier connection — no credentials in the ask.

Buying a number needed a carrier, and connecting a carrier had no verb, so a
fresh team dead-ended asking a human to paste an account id. Stormy owns the
carrier relationship; this lends it to the team, scoped by the caller's own
team access.
