Usage and limits

GET /v1/usage

GET /v1/usage gives the period consumption: used, included, remaining, policy (block|queue) and a breakdown by origin (api, contact, device). ⚠ The phone-traffic rule (Coexistence): used = api + contact; device traffic (what the owner sends from the phone) is shown but does NOT consume the plan. The PER-NUMBER limit (monthlyMessageLimit) counts only api. Per number: /v1/connections/:id/usage and /v1/usage/by-connection; informational oversubscription: /v1/accounts/oversubscription.

Buckets aggregate in UTC; the account timezone is returned only so you can caption it.

The 70/90/100% thresholds also reach you by webhook (usage.thresholdreached / connection.usagethreshold_reached).
