- **Deliverability**: `GET /v1/deliverability` and Console → Deliverability
  report delivery rates by day, carrier, and sending number, with failure
  reasons. Sharp drops raise a `deliverability.degraded` webhook event.
- **Spend limits**: a monthly USD cap on live messaging with alert thresholds
  (`GET`/`PATCH /v1/spend-limit`). Sends past the cap return
  `spend_limit_reached` and are not charged; `spend.threshold_reached`
  fires at each threshold.
- **Audit log**: key, team, webhook, spend-limit, number, consent, and
  settings changes, with actor and IP. Console → Audit log and
  `GET /v1/audit-logs`.
- **Key scopes**: restrict a key to the endpoint families it needs; others
  answer `403 insufficient_scope`. Existing keys keep full access.
- **Viewer role**: read-only teammates.
