Currently using Mapbox in an open-source project for their static map API and I wholeheartedly recommend against it. Everything but the simplest of polylines look jagged since they refuse to switch to POST requests with a json body and instead rely on you fitting in as much detail into URL query parameter length constraints.
Going to take a look at replacing them with PMTiles and my own polyline rendering.
