Docs overhaul
The documentation got a full overhaul:
  • New Quickstart, Authentication, and API conventions pages — including the documented rate limit of 1 request per second
  • Every guide rewritten around lifecycles and real payloads, with new Vendors and Inventory guides and the subscription creation flow
  • A description on every endpoint, an upgraded error reference with causes and resolutions, and playground examples that now show the minimal required payload
  • Every page can be copied as Markdown or opened in ChatGPT / Claude / Cursor from the contextual menu, and the docs are published as llms.txt for AI tools
