# Platform metadata

> Deployment-level constants, anonymously readable: currently only
the billing currency (ISO 4217 code).

Amount fields (`unit_price` / `amount` / `total_spent`) never carry a
unit; the unit lives here. Authenticated endpoints return the same
value, but anonymous rendering of a search card's `price_from` has no
access to those endpoints, hence this dedicated window.

    description: >-
      Self-service publishing channel (API Key auth), two-phase: validate first
      (validate / package, nothing persisted), then publish (POST /data-apps,
      the submission goes live as a new Release). api kind (declarative
      integration) becomes visible on publish; code kind (code package) returns
      202 and enters an async image build; once ready it is promoted to a
      Release, visible and runnable. Poll progress via GET
      /data-apps/{ref}/builds.
  - name: Runs & Results
    description: >-
