  Retail Zipline publishes no first-party client libraries or SDKs. Its GitHub
  organisation holds 79 public repositories and every one of them is a fork of a
  third-party open-source project (Rails/Ruby infrastructure, Heroku buildpacks,
  Swift utilities, Slate, Flipper, Scenic, i18n-tasks and similar) — there is no
  first-party client library, CLI or API package among them.

    unrelated to Retail Zipline, Inc. "retailzipline" does not exist. Recorded

warning: >-
  "Zipline" is a heavily collided name across registries — a drone-delivery
  company, a healthcare compliance vendor (zipline.io), a Python trading library,
  a Ruby zip-streaming gem and a self-hosted file-upload tool (zipline.diced.sh)
  all use it. None of them are Retail Zipline, Inc. No SDKs pointer is emitted in
  apis.yml.
