> Resume Ai Features

- **Tag:** billing
- **Operation ID:** `resume_ai_features_api_v1_billing_ai_resume_post`

## Description

Resume AI features for the authenticated business.

Clears ``ai_paused_at`` and ``ai_paused_by_user_id``. Idempotent —
resuming an already-active business is a no-op. Returns the
refreshed AI usage payload so the widget transitions back to the
Calm / Warning / Overage state without a second round-trip.

## Authentication

Bearer token in `Authorization` header.
Required header: `x-business-id: <business uuid>`.
