# Get Billing Usage Daily

`GET /api/app-auto-gtm/billing/usage-daily`

Per-UTC-day cold-send usage for the Billing "Usage" panel (T-638).

Counted from sent emails × price (the project-dashboard spend
convention) — one Index Only Scan, so the page opens instantly for
any org size. Replies (free) are excluded; a bounced-after-send email
stays counted (its charge is never refunded).

## Query parameters
