Measured tools (8)

• 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.

  Parameters:

  • query (required) — string
  • first — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• search_catalog

  Legacy alias for search_products. Search purchasable products across participating merchants. Prefer search_products for new shopping requests.

  Parameters:

  • query (required) — string
  • first — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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.

  Parameters:

  • site_slug (required) — string
  • product_id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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.

  Parameters:

  • site_slug (required) — string
  • variant_id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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.

  Parameters:

  • site_slug (required) — string
  • variant_id (required) — string
  • quantity — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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.

  Parameters:

  • site_slug (required) — string
  • cart_id (required) — string
  • variant_id (required) — string
  • quantity — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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.

  Parameters:

  • site_slug (required) — string
  • cart_id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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.

  Parameters:

  • site_slug (required) — string
  • cart_id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
