Compare live hotel room rates across Booking.com, Agoda, Traveloka, and OpenTravel for specific dates — which OTA is cheapest for the same property, per-room prices, and free-cancellation terms. Use when comparing hotel prices, checking room rates for a named hotel, asking which site is cheaper, or

Requires the pricewin MCP server. This skill issues no network calls of its own. Price Comparison MCP server: pricewin . Compares live rates across Booking.com, Agoda, Traveloka (crawled) plus OpenTravel (direct API). Comparison is something you do over the returned sources — there is no server side compare call. Pick the entry point by what the user gave you: User gave you Tool A city — "compare hotel prices in Da Nang" search hotels live → poll search results A named hotel — "is Mercure Danang cheaper on Agoda or Booking?" get ota hotel detail A hotel already known to be OpenTravel direct ( source: "OPENTRAVEL DIRECT" , has propertyId ) get hotel detail City wide comparison search hotels live returns IMMEDIATELY with a sessionId — it does not return hotels. 1. search hotels live — required: city , checkIn , checkOut (YYYY MM DD). Optional: adults (default 2), rooms , area , hotelName , priceMin , priceMax , language 2. Wait 5s → poll search results(sessionId, nights) 3. While status is pending or partial : wait 5s and poll again — up to 18 times (90s) 4. Present as soon as status == "partial" with hotels; keep polling silently and refine Then compare per hotel across its sources. See [ pricewin hotel search ](../pricewin hotel search/SKILL.md) for the full dedupe + presentation contract — do not restate it differently here. Single named hotel get ota hotel detail — for one specific Booking.com/Agoda hotel the user named. Required: checkIn , checkOut . Pass hotelName + city + queryText (verbatim user text) whenever known Do NOT call search hotels live for a named hotel — that returns a whole city list Live crawl, ~20–60s . Say nothing about "loading" until it actually returns Speed up: if a prior search already gave you prices.booking.url , pass it as propertyUrl to skip name resolution If it returns not found under load, retry once Returns rooms, prices, facilities, photos, reviews for that property. OpenTravel direct properties get hotel detail — only for results with source: "OPENTRAVEL DIRECT" . Pass propertyId (UUID from opentravelResults[].propertyId ) when available hotelName + city is a fallback only for a property already confirmed as OpenTravel direct Required: checkIn , checkOut . Optional: adults , children , language Returns room types with roomTypeId and ratePlanId — these are what make a property bookable ⚠️ Router rule: have a propertyId → get hotel detail . Name only → get ota hotel detail . Cancellation terms For OpenTravel rate plans only: get cancellation policy(propertyId, ratePlanId, checkInDate) → non refundable flag, free cancellation window, refund %, and the computed deadline. ratePlanId comes from get hotel detail → roomTypes[].ratePlanId . Pass checkInDate or you get no deadline. OTA hotels have no structured policy — quote whatever the crawl returned. Presenting a comparison Rank purely by price . No source gets priority, OpenTravel included Show the cheapest source first, then the others underneath: Agoda $X · Booking $Y · OpenTravel $Z Savings vs the next cheapest source: (next cheapest) / next 100 → "Save Z%" When the gap is small, prefer the free cancellation option and say why All prices USD unless the tool says otherwise. No conversion Tool inputs and response fields: [reference.md](reference.md). Security & data handling Documentation only — no code, no dependencies, no network calls of its own. The only data sent is the comparison query (city or hotel name, dates, guests, plus queryText — the user's message verbatim), to PriceWin's hosted MCP server https://mcp.price.win/mcp (no credentials, no account). No PII, and this skill cannot book or pay for anything. Full disclosure — operator, backend provenance, exact fields per tool — in [ SECURITY.md ](./SECURITY.md).
