Tools

• add_to_cart ~462 tokens
  Add a product variant (or base product) to an existing cart. Reuse the active cart_id from the chat history if one already exists. Only call create_cart first if no cart exists yet.
• apply_coupon ~119 tokens
  Apply a discount or promotional code to the cart. Returns the updated cart with discount applied.
• check_delegation ~106 tokens
  Poll for human approval of a delegation request. When status is "approved", returns the delegation_token to use as buyer_delegation_token in execute_checkout.
• compare_products ~234 tokens
  Compare products across multiple registered e-commerce sites simultaneously. Uses fail-open strategy: partial results from successful sites are returned even if some sites time out.
• create_cart ~156 tokens
  Create a new shopping cart for a specific site. Returns a cart_id. IMPORTANT: Reuse the active cart_id across multiple products in the same session. Do NOT call create_cart again if you already have a cart_id for this site in the chat history.
• execute_checkout Moves money · ~1024 tokens
  Execute checkout for a cart to create an order. Requires a buyer delegation token (from user auth) and a shipping address. The order is created UNPAID (status "pending"). IMPORTANT — do NOT stop here or just hand the user the payment_url. Immediately continue the in-chat payment flow: call get_payme
• get_active_cart ~128 tokens
  Retrieve the buyer's in-progress cart for a site (resumes a conversation). Call this before assuming a new cart when a shopping conversation continues or after a cart error. Returns the cart with its items rebuilt if the connector cart expired, or null if no cart exists.
• get_cart ~142 tokens
  Retrieve current cart contents, including items, pricing, discounts, and totals. The card already shows the line items and totals to the user, so keep your text reply to one brief sentence — do not re-list the cart contents.
• get_order ~342 tokens
  Retrieve details for an order by its ID, including items, status, shipping, and tracking information. Orders are buyer-private — pass `buyer_delegation_token` (the delegation token from this buyer's checkout approval) so the gateway can confirm the buyer owns this order. If checking if an order is p
• get_payment_methods ~228 tokens
  STEP 1 of the in-chat payment flow. Returns the payment channels available for an order (e.g. "mobile_money", "card") plus a `gateways` array of the enabled payment gateways (each with id, label, and its channels). When more than one gateway is listed, ask the buyer which they want to use and pass i
• get_payment_status ~213 tokens
  FINAL STEP of the in-chat payment flow. Returns the current PaymentSession for an order. Poll this (every ~5 seconds) after initiate_payment/submit_payment_otp until payment_status becomes "paid" or "processing" (success — the order is confirmed) or "failed" (tell the user; they can retry by initiat
• get_product ~250 tokens
  Retrieve detailed information about a specific product including variants, pricing, images, and availability. May also return `addons` — customer-selectable options defined by the store (e.g. engraving, gift wrap, size add-ons). When a product has addons, present them to the buyer and collect every
• get_product_reviews ~234 tokens
  🔍 **RECOMMENDED STEP** — Fetch product reviews and authenticity consensus before making purchase decisions. Returns: average rating, trust score (0.0-1.0), review sentiment analysis, authenticity flags (fake reviews, seller issues, negative trends), and recent reviews with verified purchase status.
• initiate_payment ~679 tokens
  STEP 2 of the in-chat payment flow. Starts a payment session for an order and returns a PaymentSession with an `instruction` the agent renders in chat. REQUIRES a buyer_delegation_token — obtain it exactly like execute_checkout: call request_delegation, have the user approve in chat, then check_dele
• list_orders ~249 tokens
  List recent orders for a site, optionally filtered by status (pending, processing, completed, cancelled, refunded). Orders are buyer-private — pass `buyer_delegation_token` (from this buyer's checkout approval); only that buyer's orders are returned.
• list_sites ~75 tokens
  List all registered e-commerce sites. Use this first to find a site by name (e.g. "Pronto Partners") and get its site_id, which is required by all other tools.
• quick_checkout Moves money · ~509 tokens
  Assemble checkout-ready cart(s) in ONE call for a multi-product (and optionally multi-store) request. Creates a cart per store, adds all items, and sets the shipping address — then returns the cart(s) with delivery options to choose. Use this when the buyer lists several products at once (optionally
• remove_from_cart ~121 tokens
  Remove a line item from the cart. Requires the item_id from the cart contents.
• request_back_in_stock ~289 tokens
  Subscribe the buyer to a back-in-stock alert for an out-of-stock product. Use when the buyer asks to be notified/told/pinged when an item restocks ("notify me when X is back", "let me know when it's in stock"). Collect the buyer's email so the alert can reach them (without it only the demand is reco
• request_delegation ~372 tokens
  Start the human delegation (approval) flow needed for checkout/payment. PREFERRED: pass the buyer's `email` — the gateway emails them a 6-digit code and returns a device_code; ask the user for the code and call submit_delegation_otp. This keeps approval fully in-chat (no link) and you never see the
• search_products ~679 tokens
  Find products on a registered store. To BROWSE a store's catalog (open-ended requests like "what do they sell", "show me what's available"), call with NO query — this returns the store's products. To SEARCH, pass `query` (a product name/keyword). Returns paginated products as an interactive card. AL
• select_shipping_option ~154 tokens
  Select one of the shipping options returned by set_shipping_address. Binds the rate to the cart so the total includes shipping; call before execute_checkout so the hosted checkout opens pre-filled.
• set_cart_quantity ~202 tokens
  Set a cart line's quantity (the server cart is the checkout source of truth, so this updates it live). Requires the item_id from the cart contents and the new absolute quantity. A quantity of 0 removes the line. Returns the updated cart card.
• set_shipping_address ~593 tokens
  Set the cart shipping destination (collected from the buyer) and return available shipping options with costs. Call after items are in the cart and before select_shipping_option. country_code is required; include postal_code/state for accurate rates.
• submit_delegation_otp ~209 tokens
  Submit the 6-digit code the buyer received by email (from request_delegation with an email) to approve the delegation in-chat. On success returns a delegation_token to use as buyer_delegation_token for checkout/payment. You cannot obtain this code yourself — the user must read it from their email an
• submit_payment_otp Moves money · ~248 tokens
  STEP 3 (mobile_money only, when initiate_payment returned instruction.action == "submit_otp"). Submits the one-time password the buyer received to authorise the mobile-money charge. REQUIRES the same buyer_delegation_token used for initiate_payment. After submitting, poll get_payment_status until pa
