36Usage export

GET /v1/usage/export?from=2026-08-01&to=2026-08-31 downloads your usage as CSV, session-authenticated, one row per day (days start at 18:30 UTC), key, model, provider and status. Columns: date, key_id, model, provider, status, requests, tokens_in, tokens_out, tokens_cached, cost_usd.

Dates are YYYY-MM-DD, from must be on or before to, and the range is capped at 92 days, a quarter, so ask for shorter windows and stitch them if you need more.
