haggl_list_vendorsread-onlyList 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 not exhaustive. haggl.ai runs each vendor's sales agent, and vendors on a paid plan pay haggl.ai for it; the list is not
haggl_start_negotiationStart 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_submit_offer.
haggl_search_catalogread-onlySearch 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 with a variant_id and approved_combinations with a recipe_id: ask with ask.items [{ variant_id, quantity }] or ask.recipe
haggl_get_negotiationread-onlyRead 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_offerRequest 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_offerAccept 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 state.commits_purchase first: merchant handoff effects may be unknown. haggl.ai never takes payment: any payment happens at the merchant'
haggl_search_discountsread-onlyFind 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 for haggl_start_negotiation. Offers are funded by each merchant, inside limits it sets; a merchant may have no offer for
haggl_create_haggl_idCreate 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: your agent can still ask merchants for offers without one. If you agree, we link the negotiations your agent opens with the
haggl_request_haggl_id_confirmationGet 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 answers confirmation_pending.
haggl_get_my_offersread-onlyRead 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_bidsHave 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 says so and returns no bids. Each bid is a merchant's own offer, funded by the merchant, with an accept_url; show the user
haggl_delete_haggl_idcan modifyDelete 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.
