Booking.com Hotel Search (Live Prices)

FlightPowers: find one hotel by name

find_hotel_by_name
Read-only

FlightPowers single-property lookup: live Booking.com availability and pricing for one named property. Input: the hotel name a person would type (adding the city helps when a chain has many properties) plus check-in and check-out dates -- no internal property ID needed, the resolution is done for you. Returns the property's price, review score, room type and a booking link. Use it to check one specific hotel, or to track a single property's price over time.

A date range and a nights value price several stays in one call, like the flights tools: pass checkin_date_from, checkin_date_to and nights (a number, or a list like [2, 3, 7]) instead of a fixed checkin_date/checkout_date, and this property is priced for every check-in date -- a rate calendar for one hotel. The answer is stays, one entry per date with that date's price and per-night rate, plus cheapest_overall. Each stay is one request billed to your plan; max_searches caps it, and a range that expands past the cap is sampled evenly across the calendar and says so in search_coverage.

price_as_seen_from prices the stay as a shopper resident in that country would see it. Gaps are real but usually modest and property-dependent, and rates move between calls, so call each country a few times on this same property before reporting a gap.

Rates go stale within minutes: never reuse an earlier result.

Requires the caller's own RapidAPI key for the Booking Live API. Get one (free tier available) at https://rapidapi.com/mtnrabi/api/booking-live-api, then pass it as an x-rapidapi-key header (preferred), a ?rapidapi_key= query parameter on the server URL, or your client's own API key field -- first non-empty wins. Usage counts against the caller's own RapidAPI plan, not ours; every response reports what it spent and what is left in api_usage. No key? Sign in with Google and the first 10 searches each day are free on this server -- ad-free, nothing to paste. Connect your own RapidAPI key at https://hotels.flightpowers.com/connect to remove the cap.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
adultsNoNumber of adult guests.
nightsNoHow many nights to stay, as a number (3) or a list ([2, 3, 7]) to price several lengths. Derives the check-out date from each check-in date, so it replaces checkout_date rather than joining it.
childrenNoNumber of children sharing the room.
currencyNoISO currency code for the prices returned, e.g. "usd".
hotel_nameYesThe property name a person would type, e.g. "Hotel Artemide". Adding the city ("Hotel Artemide Rome") disambiguates a chain with many properties. No internal property ID is needed.
checkin_dateNoFirst night of the stay, "YYYY-MM-DD". Give this with checkout_date for one stay, or use checkin_date_from plus checkin_date_to for a rate calendar.
max_searchesNoThe billed requests this call may make, up or down. One stay is one request; the cap rises by itself to cover a month-sized request, and anything past the cap in force is sampled evenly across the calendar rather than cut short at the front.
checkout_dateNoDeparture morning, "YYYY-MM-DD". Must be after checkin_date. Give either this or nights, not both.
checkin_date_toNoLast check-in date of the range, "YYYY-MM-DD".
checkin_date_fromNoFirst check-in date of a range, "YYYY-MM-DD". Needs checkin_date_to and nights, and prices this property on every check-in date in the range -- one call, a rate calendar.
price_as_seen_fromNoTwo-letter country code, e.g. "de". Prices the stay as a shopper resident in that country would see it. Call each country a few times on this same property before reporting a gap, because rates move between calls and gaps are usually modest and property-dependent.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
staysNoOne entry per stay the REQUEST asked for, in request order, present whether or not that stay was priced. Only on a date-range search (checkin_date_from / checkin_date_to / nights); a single stay does not carry it. Read this rather than inferring coverage from `results`: `results` holds the full property list for the CHEAPEST stay only, so a stay missing from it looks identical to a stay that had nothing. `reason` says which kind of hole an unpriced stay is: 'no_availability' (searched, answered, nothing came back), 'no_price' (properties came back, none carried a price), 'search_failed' (the search errored, so nothing is known -- not 'no rooms') or 'not_searched' (the per-call fan-out cap sampled it away). Counts are null rather than zero on those last two, because zero reads as 'nothing there' and neither case knows that.
caveatsNoSentences that must be read before one source is called cheaper than another -- differing rating scales, differing tax treatment, differing currencies, a source that did not answer.
messageNo
partialNoPresent when some stays failed but others were priced. Plain text saying how much of the request the answer covers.
resultsYesThe itineraries or properties found, already sorted and deduplicated. An empty array is only meaningful when search_status is 'empty'.
api_usageNoWhat this call cost the caller's own RapidAPI plan, and what remains on it. Present on every response that reached the upstream, including a degraded one -- a search that failed was still billed.
providersNoOne entry per source that was called, in the order they were requested. Only present when `providers` named more than the default source.
signup_urlNoWhere the caller subscribes or changes plan.
result_countNo
needs_api_keyNoTrue when no usable RapidAPI key arrived with the call, or the upstream rejected the one that did. No search was run and nothing was billed; signup_url and message say how to fix it.
search_statusNoDate-range searches only, except 'trial_exhausted'. 'ok': every stay searched was priced. 'empty': they all answered and none had priced availability -- a real answer. 'partial': some stays were priced and some errored. 'degraded': every stay errored, so nothing is known; safe to retry. 'trial_exhausted': the free signed-in allowance on this server is spent for today, so nothing was searched and nothing was billed; it renews at 00:00 UTC and connecting your own RapidAPI key removes the cap. Retrying does not help. 'quota_exceeded': the search was refused because the caller's remaining allowance or plan quota cannot cover the number of combinations asked for; combos_requested and combos_allowed_now carry the two numbers. Nothing was searched beyond what it cost to read the quota. Retrying the same search does not help -- ask for fewer dates or nights, or move to a larger plan.
applied_filtersNoWhich of the requested filters the upstream actually applied. Untyped: the shape is the upstream's, echoed through.
quota_exhaustedNoTrue when the caller's RapidAPI plan has no requests left for the current period.
search_coverageNoWhat was actually priced on a date-range search. Present whether or not the request was truncated, so a model can state honestly what its answer rests on.
cheapest_overallNoThe cheapest stay across everything priced, or null when nothing was. `results` holds this stay's full property list.
results_for_stayNoWhich stay `results` belongs to on a date-range search, or null when nothing was priced. Without it the rows read as 'the search's results' and get quoted against the wrong dates.
providers_skippedNoSources that were NOT called, each named with why and where to subscribe. A source here contributed nothing to results and is counted nowhere. It is listed rather than dropped because a silently missing source is indistinguishable from a source that had nothing.

A4.6/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, and the description adds substantial behavioral detail beyond that: 'Rates go stale within minutes: never reuse an earlier result,' the max_searches cap with even sampling, the price_as_seen_from caveat to call multiple times before reporting a gap, and billing/API key implications. No contradiction exists; the description enriches an already well-annotated safety profile.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long but well-structured and front-loaded with the core purpose. Each paragraph has a distinct role: inputs, rate calendar, currency handling, staleness, and authentication. Some redundancy exists with schema descriptions (e.g., hotel_name can include the city, no internal ID needed), but the length is justified by the tool's complexity and the need to explain billing and data freshness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (11 parameters, rate calendars, billing caps, auth requirements, live data variability), the description is remarkably complete. It covers the return shape (price, review score, room type, booking link; stays for calendars), explains max_searches sampling, warns about stale rates, details authentication paths, and sets expectations for price_as_seen_from. The presence of an output schema further reduces the need to spell out every field, so nothing critical is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds meaningful relational context: it explains how checkin_date_from/checkin_date_to/nights create a rate calendar, clarifies that nights replaces checkout_date rather than joining it, and describes max_searches sampling behavior. These go beyond the schema's per-parameter descriptions, making the combined guidance more actionable.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'single-property lookup: live Booking.com availability and pricing for one named property.' It clearly differentiates from siblings by stating it finds exactly one hotel by name, and later reinforces 'Use it to check one specific hotel, or to track a single property's price over time.' This leaves no ambiguity about what the tool does or how it differs from search or comparison tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context for when to use the tool: checking one specific hotel or tracking a single property over time. It also explains the rate calendar flow and when to use date ranges instead of fixed dates. However, it does not explicitly name sibling tools or state when not to use this tool in favor of compare_hotel_rates or search_hotels, so it falls just short of full explicitness.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
