Unlike the other fields in a 0x order, it is not guaranteed to be correct as it is derived from whatever mechanism the implementer (ie. the relayer) is using. While convenient for prototyping and low stakes situations, we recommend validating the value of the field by checking the state of the blockchain yourself, such as by using [Order Watcher](https://0xproject.com/wiki#0x-OrderWatcher). - -# Misc. - -- All requests and responses should be of **application/json** content type -- All token amounts are sent in amounts of the smallest level of precision (base units).
