Graphorin API reference / @graphorin/core / / Cost

Interface: Cost

Defined in: packages/core/src/types/usage.ts:46

Stable

Money figure attached to a Usage. Always carries a 3-letter currency code so that consumers can perform aggregation safely.

Properties

Property	Type	Description	Defined in
amount	number	Amount in WHOLE units of currency - for USD that is dollars, and fractional values are expected (a typical LLM call costs a fraction of a cent, e.g. 0.0042). This is deliberately NOT "minor units" / cents: the canonical producer - calculateCost in @graphorin/pricing - and every consumer (CostTracker in @graphorin/observability, the memory consolidator's costUsd budget, persisted checkpoints) already operate in whole currency units, and sub-cent per-call figures make minor units impractical. Do not divide by 100.	packages/core/src/types/usage.ts:58
currency	string	ISO-4217 currency code; default 'USD'.	packages/core/src/types/usage.ts:60
