Tokens and Metering

How tokens are tracked

Every API call is metered at the token level and attributed to a specific Unit, Lot, and trade. The system always draws from the Lot closest to expiration first (FIFO). This metering chain connects your real-time usage back to the market transaction that funded it, giving both developers and suppliers an auditable record of what was delivered, by whom, and at what cost.

• For every call, the platform counts input and output tokens using metering components that are specific to categories of models.

• It subtracts the tokens from the oldest Lot (i.e. the lot that is closest to expiration) in your Consumption Account.

• It records the mapping between the call, the Lot and the Unit to consume from, the trade that funded it, and the Supplier that served it.
