12 tools

• haggl_list_vendors

  List vendors that accept AI-agent price negotiations through haggl.ai. A vendor appears once haggl.ai is installed on its own store or website (the listed website): the haggl.ai Shopify app on that store, or its snippet detected on that site. Vendors can opt out, so the list is…

• haggl_start_negotiation

  Start a price negotiation with a vendor. Returns contextual guidance, current permitted actions and a new session with a session id. No customer-profile selection is required. Skip this tool if REST initialization already returned a session; pass that session.id directly to…

• haggl_search_catalog

  Search a vendor's catalog so the offer can name exact products, then follow the how_to_ask field of the result. A store catalog returns products with a handle, price and collections: ask with ask.items [{ product_handle, quantity }]. A campaign catalog returns eligible variants…

• haggl_get_negotiation

  Read the canonical state, current offer version, guidance and permitted actions of an existing negotiation. Use after human changes, reloads, transport switches or uncertain results; this does not open another session.

• haggl_submit_offer

  Request a quote using all context already available. Buyer data and evidence can be omitted; relevant additional context can be supplied later within the remaining rounds. Returns authorized terms or no offer, contextual guidance and permitted next actions.

• haggl_accept_offer

  Accept the vendor's offer and lock in the deal. Consequential: only call after the buyer has approved this exact offer, every time. Provide the offer version the buyer reviewed and approved; a changed offer needs a new approval. Read state.acceptance_effects and…

• haggl_search_discounts

  Find merchants that run a sales agent on haggl.ai, by business name, website or kind of product. Only when the user asks for a discount, a coupon, a promo code or a lower price; a purchase at the listed price is not a request for one. Returns matching merchants with a vendor_id…

• haggl_create_haggl_id

  Create a haggl ID for the user, so offers and codes from different merchants stay together and can be read back later. Show the user this text first, and call this only if they agree: "haggl.ai, operated by MOOJO.ID, INC. ("we"), offers your agent a haggl ID. You can decline…

• haggl_request_haggl_id_confirmation

  Get a link for the user to read the haggl ID consent text and confirm it on haggl.ai, when they are not in this conversation to agree to it. Send them confirm_url (valid 30 minutes). After they confirm, call haggl_create_haggl_id with the returned confirmation; until then it…

• haggl_get_my_offers

  Read what haggl.ai holds for the user's haggl ID: when it was created and the negotiations, offers and codes linked to it, newest first.

• haggl_get_bids

  Have the merchants on haggl.ai in one shopping category (for example travel) bid for the user at once, from their haggl ID record, without new proof. Works once the record holds a verified purchase in that category (from an earlier offer with signed email proof); otherwise it…

• haggl_delete_haggl_id

  Delete the user's haggl ID and unlink the offers linked to it. Only when the user asks. Codes already issued keep working at the merchant until they expire.
