 \-&nbsp;`per_km_pricing` <br/>*(added in v2.2)* | OPTIONAL | Array | Array of segments when the price is a function of distance traveled, displayed in kilometers.<br /><br />Total cost is the addition of `price` and all segments in `per_km_pricing` and `per_min_pricing`. If this array is not provided, there are no variable costs based on distance.
 &emsp;&emsp;\-&nbsp;`start` <br/>*(added in v2.2)* | Conditionally REQUIRED | Non-Negative Integer | REQUIRED if `per_km_pricing` is defined. The kilometer at which this segment rate starts being charged *(inclusive)*.
 &emsp;&emsp;\-&nbsp;`rate` <br/>*(added in v2.2)* | Conditionally REQUIRED | Float | REQUIRED if `per_km_pricing` is defined. Rate that is charged for each kilometer `interval` after the `start`. Can be a negative number, which indicates that the traveler will receive a discount.
-&emsp;&emsp;\-&nbsp;`interval` <br/>*(added in v2.2)* | Conditionally REQUIRED | Non-Negative Integer | REQUIRED if `per_km_pricing` is defined. Interval in kilometers at which the `rate` of this segment is either reapplied indefinitely, or if defined, up until (but not including) `end` kilometer.<br /><br />An interval of 0 indicates the rate is only charged once.
+&emsp;&emsp;\-&nbsp;`interval` <br/>*(added in v2.2)* | Conditionally REQUIRED | Non-Negative Float <br/>*(as of v3.0-RC2)* | REQUIRED if `per_km_pricing` is defined. Interval in kilometers at which the `rate` of this segment is either reapplied indefinitely, or if defined, up until (but not including) `end` kilometer.<br /><br />An interval of 0 indicates the rate is only charged once.
 &emsp;&emsp;\-&nbsp; `end` <br/>*(added in v2.2)* | OPTIONAL | Non-Negative Integer | The kilometer at which the rate will no longer apply *(exclusive)* for example, if `end` is `20` the rate no longer applies at 20.00 km.<br /><br /> If this field is empty, the price issued for this segment is charged until the trip ends, in addition to the cost of any subsequent segments.
 \-&nbsp;`per_min_pricing` <br/>*(added in v2.2)* | OPTIONAL | Array | Array of segments when the price is a function of time traveled, displayed in minutes.<br /><br />Total cost is the addition of `price` and all segments in `per_km_pricing` and `per_min_pricing`. If this array is not provided, there are no variable costs based on time.
 &emsp;&emsp;\-&nbsp;`start` <br/>*(added in v2.2)* | Conditionally REQUIRED | Non-Negative Integer | REQUIRED if `per_min_pricing` is defined. The minute at which this segment rate starts being charged *(inclusive)*.
 &emsp;&emsp;\-&nbsp;`rate` <br/>*(added in v2.2)* | Conditionally REQUIRED | Float | REQUIRED if `per_min_pricing` is defined.  Rate that is charged for each minute `interval` after the `start`. Can be a negative number, which indicates that the traveler will receive a discount.
-&emsp;&emsp;\-&nbsp;`interval` <br/>*(added in v2.2)* | Conditionally REQUIRED | Non-Negative Integer | REQUIRED if `per_min_pricing` is defined. Interval in minutes at which the `rate` of this segment is either reapplied indefinitely, or up until (but not including) the `end` minute, if `end` is defined.<br /><br />An interval of 0 indicates the rate is only charged once.

 \-&nbsp;`surge_pricing` <br/>*(added in v2.2)* | OPTIONAL | Boolean | Is there currently an increase in price in response to increased demand in this pricing plan? If this field is empty, it means there is no surge pricing in effect.<br /><br />`true` - Surge pricing is in effect.<br />  `false` - Surge pricing is not in effect.
