## OpenAPI

````yaml /api-reference/openapi.json get /v1/sessions
openapi: 3.1.0
info:
  title: Brewgravity API
  version: 1.0.0
  description: >-
    Read and write your recipes, brew sessions, fermentation logs, and
    ingredient inventory.


    Every request is scoped to the account its credential belongs to — there is
    no `user_id` parameter anywhere, and an id belonging to someone else returns
    `404`.


    All units are metric: kilograms, grams, litres, degrees Celsius, minutes.
