# Usage rollup

> Run counts, tokens and spend for your organization over a window. Requires `usage_read`.

The window is half-open, `[start_at, end_at)`, and counts runs created inside it. Omit both bounds for the current UTC calendar month.

    The OpenType HTTP API: decision runs on Neon 1.1, API keys, usage, quota and
    billing. Every `/v1` route takes `Authorization: Bearer <credential>`, where
    the credential is an API key (`otsk_` followed by 64 hex characters) or a
    console session token. Amounts are integers in micro-USD (1,000,000 = 1 US
    dollar). Errors share one envelope, `{"error": {"code", "message",
    "request_id"}}`. Stripe is named only where it hosts checkout, the billing
    portal and receipts.
