 ### Prices
 
-Each price must include at least one supported currency.
+Each price must include at least one supported currency. Currency amounts are decimal strings in `"<integer>"` or `"<integer>.<decimals>"` format (e.g. `"9.99"`, `"0.01"`, `"1000"`). Do **not** use cent integers — to represent $9.99, write `"9.99"`, not `999`.

 | --- | --- | --- | --- |
-| `payments.products.<productId>.prices.<priceId>` | `{ USD?: string, EUR?: string, GBP?: string, JPY?: string, INR?: string, AUD?: string, CAD?: string, interval?: DayInterval, serverOnly?: boolean, freeTrial?: DayInterval }` | `{ serverOnly: false }` | Defines one price. Include at least one currency amount. `interval` makes it recurring; leave it unset for a one-time price. `serverOnly` hides the price from client SDK responses. `freeTrial` applies to this specific price. JPY amounts cannot have decimals. |
