Hint Inc. is a San Francisco based beverage company founded in 2005 by Kara Goldin, known for fruit-infused unsweetened water sold in still, sparkling, caffeinated and kids formats across 25+ flavors. A large share of its business is direct-to-consumer through its own storefront at drinkhint.com, which runs on Shopify. Hint publishes no traditional developer program, SDKs or OpenAPI, but the storefront does expose a live, anonymous agent surface: an agents.md / llms.txt agent instruction document, a Universal Commerce Protocol (UCP) merchant profile at /.well-known/ucp, and a Model Context Protocol endpoint at /api/ucp/mcp that answers tools/list with 13 real catalog, cart, checkout and order tools. Checkout explicitly requires contemporaneous human approval before payment.
