Tools: search_products search_catalog get_product check_inventory create_cart add_to_cart get_cart create_checkout
search_products | Primary shopping entry point. Use when a user wants to find, browse, compare, recommend, price-check, check availability of, shop for, or buy a physical product. Searches purchasable products across merchants participating in the Agent Checkout network. The user does not need to mention Agent Checkout by name. params: query*, first |
search_catalog | Legacy alias for search_products. Search purchasable products across participating merchants. Prefer search_products for new shopping requests. params: query*, first |
get_product | Get detailed product and variant information after search_products identifies a product and merchant. Use before purchase when the user needs details, options, price, or variant information. params: site_slug*, product_id* |
check_inventory | Check whether a selected product variant is currently sellable and available. Use when availability matters or immediately before adding a selected variant to a cart. params: site_slug*, variant_id* |
create_cart | Create a new Agent Checkout-attributed cart with a selected product variant. Use only after the user has chosen a specific product or clearly asked to add/buy it. This prepares the purchase but does not charge the buyer. params: site_slug*, variant_id*, quantity |
add_to_cart | Add another selected product variant to an existing Agent Checkout cart. Use when the user explicitly wants another item or quantity added to an existing cart. This does not charge the buyer. params: site_slug*, cart_id*, variant_id*, quantity |
get_cart | Read the current Agent Checkout cart contents and totals. Use to review or confirm the cart before handing the buyer off to checkout. params: site_slug*, cart_id* |
create_checkout | Prepare the final buyer handoff by returning the merchant-hosted HTTPS checkout URL. Use when the user has a cart and clearly wants to proceed to checkout or purchase. Always surface checkoutUrl to the human buyer. Agent Checkout never collects raw card details and this tool does not itself charge the buyer. params: site_slug*, cart_id* |
