  description: >-
    HTTP/JSON view of the Depot API. Depot's API is built on Connect, which
    offers multiprotocol support for gRPC, gRPC-Web, and HTTP/JSON over the same
    services. Each remote procedure call (RPC) is invoked as an HTTP POST to a
    path of the form /{package}.{Service}/{Method}, with a JSON request body and
    a JSON response body. This document models the documented services for
    managing projects, project tokens, builds, and BuildKit connections. All
    requests are authenticated with a Bearer token (an organization API token,
    user token, or project token) in the Authorization header.
