Price-insights check with Claude Code

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.

Step 1 · Connect

Install the open-source skills

Eight MIT-licensed skills (cheapest dates, fare watch, trip planning, hotel search, rate-parity monitoring…). They talk to the same API over MCP or plain REST with your key.

npx skills add mtnrabi/travel-agent-skills

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 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": "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 | null

The 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 | null

The 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" | null

Google’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 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 Claude Code and calls the hosted API over the network. Nothing to deploy, nothing to keep warm.
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.
