Water Softener Plus welcomes AI shopping assistants and buying agents. You can find products, check out, and negotiate prices programmatically.

Price negotiation (MCP server)

Endpoint: https://134-199-203-107.sslip.io/mcp (Model Context Protocol, Streamable HTTP, JSON-RPC 2.0, no login required)

  • request_offer: send Shopify variant ids and quantities, the buyer's email, and an optional target total. Replies are accept, counter, list_price, quote_required or decline.
  • get_offer_status: check an offer and get the invoice link once approved.

Ask again to negotiate further (up to 3 rounds). To accept a counter offer, call request_offer again with target_total equal to the offered total. Agreed deals become a Shopify invoice for the exact items, valid for 48 hours, paid through Shopify checkout.
