Public results should be treated as the current published TradeKind record. A missing field does not mean a negative answer: for example, unknown availability should remain unknown rather than being converted into “available” or “unavailable”.
Service areas, reviews, business details and other profile information can change. Systems using TradeKind should prefer the current canonical page or public endpoint over cached copies when freshness matters.
TradeKind does not ask crawlers or assistants to treat a listing as an endorsement. Homeowners remain responsible for deciding which business to contact and whether to agree any work.
