  ModRetro publishes no API plans, tiers, quotas or developer pricing of any kind. Its agent surface
  (the UCP/MCP commerce endpoint, the storefront product JSON, /agents.md and /llms.txt) is free and
  open to any agent that supplies a UCP agent profile; the only thing priced on modretro.com is
  merchandise — consoles, cartridges and accessories sold through the Shopify storefront. There is
  no developer portal, no API key issuance, and no "contact sales" API gate either, so this is a
  genuine zero rather than an enterprise wall.
