Privileged Scope This endpoint requires a privileged scope to be used in production by all Uber riders. You can use this endpoint immediately when authenticated as yourself or any of your 5 registered developers. When you are ready to distribute your application broadly for use by all Uber riders, you may request FULL ACCESS. For more information read about scopes.

Ride Request - Estimate

The Request Estimate endpoint allows a ride to be estimated given the desired product, start, and end locations. If the pickup ETA is null, there are no cars available even if an estimate may still be given to the user.

You should use this endpoint to get an upfront fare before requesting a ride. In some products upfront fares are not enabled so you can use this endpoint to determine if surge pricing is in effect for the product/location. Do this before attempting to make a ride request so that you can preemptively have a user confirm surge by sending them to the surge_confirmation_href provided in the response.

This endpoint will either return an upfront fare (in the fare key) or a range estimate (in the estimate key) depending on the configuration of the product.

See the Ride Request tutorial for a step-by-step guide to requesting rides on behalf of an Uber user. Please review the sandbox documentation on how to develop and test against these endpoints without making real-world Ride Requests and being charged.
