Description

CouponX helps shoppers find merchant-published US coupons from a bounded, dated inventory. Search by retailer, storefront domain or code; inspect an offer's terms and source; compare potential savings on one retailer's USD basket; and display interactive coupon cards. CouponX distinguishes eligible savings from conditional estimates and leaves shipping unknown when it has not been supplied. It does not assume coupon stacking, test checkout, compare product prices, buy goods or manage merchant accounts. An empty result describes CouponX's stored inventory, not all coupons available elsewhere. The public connection is read-only and requires no CouponX account. Published offers are not checkout-verified. Inventory freshness, merchant exclusions and final checkout eligibility remain visible. Purchases and payments occur on retailer websites. Supported offers concern US shopping in USD, including when the plugin is used from another country.

Tools

4 tools agents can invoke

Use this when a user wants to know which stored coupon saves most on a basket at one retailer, including requests that do not mention CouponX. Requires a known merchant and subtotal in integer minor currency units. Live inventory is the default. Compare single offers under stored eligibility rules; keep missing facts conditional, shipping unknown when not supplied, and eligible savings separate from potential savings. Excludes tax and unknown fees, never assumes stacking and does not test checkout. After comparison call show_coupon_board with result IDs and the same basket facts. This is not a product-price comparison or purchasing tool. Demo results are simulations.
compare_basket_offers
Use this when a user wants terms, expiry, source evidence or restrictions for a previously returned CouponX offer ID. Fetch the complete stored details without accessing the retailer or testing checkout. Use show_coupon_board for an available offer when a visual view helps.
get_coupon_offer
Use this when a user wants coupons, promo codes, discount offers or free shipping for a US online purchase, or is preparing to buy from an identifiable retailer, even without mentioning CouponX. Query a store name/domain or a coupon code; use category alone for broad category offers. This reads a bounded stored inventory, not product prices, stock or the whole web. Do not use for non-shopping questions or financial bond coupons. Live mode is the default and omits expired, paused and source checks older than 72 hours. Empty results only describe this inventory. After selecting relevant result IDs, call show_coupon_board to display them. Never present demo codes as redeemable or published offers as checkout-tested.
search_coupon_offers
Display an interactive CouponX coupon board inside chat. First search_coupon_offers, get_coupon_offer or compare_basket_offers, then pass up to 12 result offer IDs in display order. For a basket comparison, also pass the same basket facts and inventory mode. The server reloads current offers and recalculates savings; do not invent IDs or prices. Pass an empty offerIds array for an empty result. Use after coupon searches and comparisons so shoppers can inspect terms, copy codes and compare their basket visually.

How do I improve CouponX's ChatGPT Plugin discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
