Grants and usage history

What it is

Grants add usage units. Usage history shows grants, refunds, reservations, commits, releases, spends, and rejections.

When to use it

Use Grants and Usage History for support, customer balance debugging, and retry-safe backend writes.

How to use it

How they work

A grant adds usage units with a stable business reference. A usage event records what changed later. Refund and refund-reversed events are matched safely against buckets and never drive balances below zero. Details keep provider event metadata when available.
