Check dates and total pricing on a published property's public host website. Send its property id, arrival/departure (YYYY-MM-DD) and guests; no guest contact or card details. Availability may be unknown even when a price is returned. Optional startingNightlyPrice is an advertised starting nightly rate, separate from price.total; never multiply it into a stay total or infer dates, party, fees or tax coverage. partyBasis:all_adults means every occupant was priced as an adult; disclose that assumption, since child ages are not collected. Inspect reason, price.completeness, actual currency, checkedAt and expiresAt. Optional execution:browser requests the experimental selected-home browser agent on reviewed Stays sites and may take up to two minutes including source discovery; omit it for fast automatic execution. Search never starts this agent. Recent matching quotes may be reused until expiry; a pending search check is joined rather than repeated. The host may create an expiring anonymous price draft. A quote never reserves or confirms a booking; held is always false. Unsupported/protected sites return unknown. No host integration or credentials are required.
