Stannp is a direct mail platform that lets businesses send physical postcards and letters through a REST API, and this endpoint is the account piece of that service. A developer or operations team running mail campaigns would use it to check what is left on the account before triggering sends. Stannp serves businesses in the UK, US and Canada. The API uses API key authentication over HTTPS and returns a simple JSON envelope.
