TrackUsage

Record usage in the same transaction that checks the allowance.

Source: packages/paykit/src/Billing/TrackUsage.binding.ts Kind: Binding · Product: Usage · Provides: Paykit.TrackUsage

Record usage in the same transaction that checks the allowance. A blocking allowance refuses before anything is written; an idempotencyKey makes a retry a replay. This is the metered charge: it prices from the catalog and writes the money on the event, and it never calls a provider — the period close is what tells the vendor.

The account is the bind and the request is the rest, so a second account is not representable:

Recording usage

const trackUsage = yield* Paykit.TrackUsage(account);

yield* trackUsage({ featureId: "messages", value: 1, idempotencyKey: requestId });

Holding capacity instead

Work that has started but not finished belongs in Paykit.Hold, which takes the units now and bills only what ran.
