The Yandex.Maps API offers a range of services for using Yandex technologies and map data in your projects. You can use the API for virtually anything: show directions to your office, or display data on the map for visual analytics.
If something changes in Yandex.Maps (for instance, a new company is added or a highway interchange opens), these updates are immediately available in your project.
The HTTP API is a set of services for using HTTPS requests to access individual features of the Yandex.Maps API.
You can use the Yandex.Maps API for free if you agree to the terms and conditions.
