Change a listing
Prepares a change to the asking price or quantity of one listed line of the customer's portfolio (portfolio_id from list_my_listings, get_my_portfolio or the offer list_for_sale or an earlier change answered with), which changes that line's units only, or of a whole listing by its code. A repriced line gets a new portfolio_id. For wine held outside Cru (stock_type "external"), lowering the quantity removes those units from the portfolio; for wine stored with Cru, they just come off sale. BPO stock (stock_type "bpo") cannot be changed. The result's offer is the wine as list_my_listings gives it, with only the lines the changed units are on now. This only prepares the instruction: it returns a summary and a confirmation_code and changes nothing until confirm_instruction is called with that code, after the customer agrees. Prices are normal amounts in the market currency - 12345.5 is 12,345.50 - and every market states its currency.
offer.update, and changes nothing With a connected app’s token, Cru checks the request against live data and either refuses it with a reason or returns a summary and a confirmation code. Nothing happens until confirm_instruction is called with that code — once, within 15 minutes, after the customer says yes.
A partner key is offered this tool opening “Changes the asking price” instead of “Prepares a change to the asking price”. It is carried out at once, with no confirmation step, and takes a required reference as its last argument, so sending the same one again returns the first result. It returns the action’s result as the REST response’s data gives it, with replayed, and is marked destructiveHint. Partner keys over MCP →

The same object also comes as JSON text in content, for hosts that read only that. What a staging tool returns →
Errors
A refusal — a wine that is not on Cru, a price out of range — comes back as a result with isError: true and a message worded for the assistant to act on. A connection without offers:write is not offered this tool, and calling it anyway returns 403 with a JSON-RPC error naming the scope. Missing or invalid credentials return 401.
