Overview

Bearing between two points.

Authentication

Every request requires the x-api-key header. Credits used and remaining quota are returned in response headers (x-api-credits-used, x-api-remaining-credits, x-rate-limit-*).

Request

GET https://api.apikodu.com/api/v1/maps/bearing?fromLatitude=40.98765&fromLongitude=29.02541&toLatitude=41.037&toLongitude=28.985

Query string.

Parameters

Name	Type	Required	Default	Options	Description
`fromLatitude`	number	* Required	—	—	From latitude.
`fromLongitude`	number	* Required	—	—	From longitude.
`toLatitude`	number	* Required	—	—	To latitude.
`toLongitude`	number	* Required	—	—	To longitude.

Response

Name	Type	Description
`bearingDegrees`	number	Initial bearing from start to end. 0–360 degrees. 0=north, 90=east.
`bearingRadians`	number	The same bearing in radians.

Errors

HTTP	code	Description
