Recipe · Flights API
Price-insights check with Smithery
The recipe that only this API can run: the agent compares a quoted fare against Google’s own price band for the route and dates. Below the band’s low end → take it; above the high end → wait. The verdict field gives the agent a defensible recommendation with a source.
Free tier on RapidAPI. No card to try.
Step 1 · Connect
Install from the Smithery registry
Qualified names verified against the live Smithery pages on 2026-08-26. The gateway proxies the connection and forwards the key you set in the server config, so usage still meters on your own RapidAPI subscription. Connecting to flights.flightpowers.com and hotels.flightpowers.com directly is one hop shorter and works identically.

Set rapidapi_key in the server's configuration on Smithery.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.
“I was quoted $129 for JFK→Cancún on January 1. Should I take it?”
Step 3 · Under the hood
What the agent calls
No glue code: the agent reads the tool schema, picks the tool, and fills these parameters from your prompt.
// search_oneway_flights
{
"from_airport": "JFK",
"to_airport": "CUN",
"departure_date": "2027-01-01",
"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.
price_insights_lownumber | nullThe bottom of Google’s historical price band for this route and dates. Null when Google doesn’t publish a band: treat the fare as unjudged, not bad.
price_insights_highnumber | nullThe top of the band. A fare above it is expensive for the route by Google’s own history.
price_range_in_relation_to_other_periods"low" | "typical" | "high" | nullGoogle’s verdict on the current fare against that band, the single field alerting, ranking, and “book now” logic branch on.
Questions, answered plainly
- Is my key billed to me?
- Yes. The MCP server is bring-your-own-key: Smithery sends your RapidAPI key with each call and usage 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 MCP servers are hosted at flights.flightpowers.com and hotels.flightpowers.com: you add a URL to Smithery, not a deployment.
- What does it cost?
- 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.
