Is there a way to get through the API (Yandex.Maps, Google Maps) an array of coordinates between two given points? Or maybe there are calculation methods? Coordinates are needed lying on a line between two points, there is no need to calculate the passage.

    Well, all the coordinates can not be obtained (they are just an infinite number), but to go through an arc of a large circle with some step - you can

    Here, for example, interpolate from google.maps.geometry.encoding namespace

     interpolate(from, to, fraction) Parameters: from: LatLng to: LatLng fraction: number

    Under the hood is probably used SLERP . If you need to independently implement - Intermediate point here

    Can be calculated

     Formula: a = sin((1−f)⋅δ) / sin δ b = sin(f⋅δ) / sin δ x = a ⋅ cos φ1 ⋅ cos λ1 + b ⋅ cos φ2 ⋅ cos λ2 y = a ⋅ cos φ1 ⋅ sin λ1 + b ⋅ cos φ2 ⋅ sin λ2 z = a ⋅ sin φ1 + b ⋅ sin φ2 φi = atan2(z, √x² + y²) λi = atan2(y, x) where f is fraction along great circle route (f=0 is point 1, f=1 is point 2), δ is the angular distance d/R between the two points.

    I join the answer above, also an example of a simple implementation can be found here https://tech.yandex.ru/maps/jsbox/2.1/polyline_animation in the generateSmoothCoords function
