Why it costs less
Our Claude API comes from a pool of official subscription accounts and is billed at the official list price times one discount.
Tools like Claude Code resend the same context on every turn. Tokens read from the cache are billed at the official cache read rate, far below the input rate.
Every call on the record
Your usage log lists the model, token counts, list price, and your price for each call.
