Is my key billed to me?

Yes. The skill uses your own RapidAPI key, so every call meters against your own subscription on RapidAPI. There is no FlightPowers account and no second bill.

Does this need a server of mine?

No. The skill runs inside OpenClaw and calls the hosted API over the network. Nothing to deploy, nothing to keep warm.

The Google Flights Live API's free tier is 10 requests/month with a hard cap: enough to verify your key works, not to evaluate. The PRO plan is $10/month for 2,500 requests, and every plan includes every endpoint. A single daily check is about 30 requests a month: past the free tier’s 10, comfortably inside PRO.

Fare-alert cron with OpenClaw

The verdict field makes alerting trivial: poll on a schedule and fire only when price_range_in_relation_to_other_periods === "low". No home-grown price-history database needed, because Google’s band IS the history. Send the buy_link in the alert so the user can book from the notification.

Step 1 · Connect

Install the ClawHub skill

Also available: clawhub.ai/mtnrabi/booking-hotel-search for hotels. The skill wraps the same live API with your key.

install

clawhub install mtnrabi/google-flights-realtime-api

Bring your own RapidAPI key: every request is billed to your own subscription, never ours.

Step 2 · Ask it

The prompt

Verbatim: paste it, or anything shaped like it. The agent maps it to the call below.

“Every morning, check JFK→LHR fares for my December dates and alert me when Google’s verdict flips to low.”

Step 3 · Under the hood

What the skill calls

The skill calls the same API with your key. This is the call behind the answer, with real parameter names.

the call the skill makes

// search_oneway_flights
{
  "from_airport": "JFK",
  "to_airport": "LHR",
  "departure_date": "2026-12-10",
  "limit": 3
}

Step 4 · Read the response

Fields your logic reads

The response is flat JSON. These are the fields this recipe branches on, with what each one means.

pricestring

The fare as Google Flights displays it: “$56”. The numeric twin price_as_number rides alongside for sorting and arithmetic.

price_range_in_relation_to_other_periods"low" | "typical" | "high" | null

Google’s verdict on the current fare against that band, the single field alerting, ranking, and “book now” logic branch on.

buy_linkstring (URL)

A Google Flights deep link that reopens this exact itinerary. Hand it to the user; it just works.
