Mapbox attribution is the combination of two visual elements that are placed on all Mapbox maps: the Mapbox wordmark and text attribution. Together, these two elements state that a map was created with Mapbox tools and data.
The Mapbox wordmark is a small image that contains the stylized word "Mapbox" and the Mapbox logo.
The text attribution contains at least three links: © Mapbox, © OpenStreetMap, and Improve this map. Text attribution is strictly required when you use the Mapbox Streets tileset, due to OpenStreetMap's data source ODbL license. Some other Mapbox-provided tilesets require additional attribution, which is stored in the TileJSON of the tileset.
