Overview

Onsellr Marketplace helps people in Australia search, compare and research cars listed on Onsellr. Buyers can open listing details, check availability and, after signing in, request an enquiry, test drive, finance information, trade-in conversation or refundable holding deposit through Onsellr.

Tools

cancel_marketplace_action

ChatGPT
Cancel a prepared action if the buyer declines. Idempotent.

confirm_marketplace_action

ChatGPT
Execute a previously-prepared marketplace action after the buyer's explicit go-ahead. Requires the confirmationId returned by the prepare_* call.

marketplace_check_availability

ChatGPT
Cheap status probe for a single listing. Returns available / reserved / sold / not_found.

marketplace_compare_vehicles

ChatGPT
Side-by-side comparison of up to 4 listings. Returns redacted detail for each.

marketplace_conversation_history

ChatGPT
Return your buyer-visible chat history for one of your Onsellr conversations.

marketplace_lead_view

ChatGPT
Buyer-side view of ONE of the buyer's active leads/conversations on Onsellr — the listing they enquired on (strictly redacted: anonymised seller, no dealer name/phone/address/website/LMCT), the message thread to date, and the lead status. Pass conversationId from marketplace_conversation_history or a prior search. The buyer can only view conversations they own; another buyer's conversation returns forbidden.

marketplace_listing_detail

ChatGPT
Full redacted detail for a single listing.

marketplace_my_deposits

ChatGPT
List the refundable holding deposits YOU have placed through Onsellr — id, vehicle title, amount, status (pending_payment/paid/refunded/cancelled/expired) and dates. Use this to find the depositId to pass to marketplace_refund_deposit when the buyer wants a refund in a new session. Strictly redacted: the seller's identity is never revealed. Only your own deposits are returned.

marketplace_refund_deposit

ChatGPT
Request a refund or cancellation of a refundable holding deposit YOU previously paid through Onsellr. Onsellr issues the Stripe refund and releases your hold — the seller's identity is never revealed. Pass the depositId returned when you paid the deposit. Idempotent: refunding an already-refunded deposit is safe.

marketplace_search_stock

ChatGPT
Search active Onsellr listings by make/model/year/price/body/fuel/location. Returns redacted listing cards (no seller identity).

marketplace_send_message

ChatGPT
Post a follow-up message into one of your open Onsellr conversations with a seller.

prepare_marketplace_deposit

ChatGPT
Stage a refundable holding deposit on a specific vehicle, paid securely through Onsellr. The deposit amount is set by Onsellr from the listing price (the buyer cannot choose it). Returns a humanSummary with the exact amount to show the buyer; confirm_marketplace_action then returns a secure Stripe payment link. Onsellr processes the payment on the seller's behalf and the seller's identity stays anonymous. Deposits only — never a final or drive-away payment.

prepare_marketplace_enquiry

ChatGPT
Stage a buyer enquiry on a listing. Buyer must have ticked the in-market consent box. Surface the returned humanSummary to the buyer for explicit approval before calling confirm_marketplace_action.

prepare_marketplace_finance_enquiry

ChatGPT
Stage a finance interest enquiry — forwards to Auto Asset Finance via the existing finance-lead pipeline.

prepare_marketplace_test_drive_request

ChatGPT
Stage a test-drive request. Caller must confirm in-market consent.

prepare_marketplace_trade_in_enquiry

ChatGPT
Stage a trade-in offer alongside the enquiry. Buyer describes their current vehicle.
