Is my key billed to me?

Yes. The MCP server is bring-your-own-key: ChatGPT 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 ChatGPT, not a deployment.

The Booking.com 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 2,000 requests, and every plan includes every endpoint.

Rate-parity check with ChatGPT

One call per market, identical except proxy_country, a two-letter code that routes through a residential proxy in that country. The agent compares the quotes and reports the spread. In a real capture on 2026-08-26 the US market saw the same room $195 cheaper than Germany and Israel.

Step 1 · Connect

Add the MCP server as a connector

Settings → Connectors (developer mode) → add the server URL. The key rides on the server URL; ChatGPT never sees it in chat.

connect

https://flights.flightpowers.com/mcp?rapidapi_key=YOUR_RAPIDAPI_KEY

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.

“Price the Rixos Sungate in Antalya for Oct 5–10 as seen from the US, Germany, and Israel.”

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.

tool call

// find_hotel_by_name
{
  "hotel_name": "Rixos Sungate",
  "area": "Antalya",
  "checkin_date": "2026-10-05",
  "checkout_date": "2026-10-10",
  "proxy_country": "us"
}

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.

availableboolean

False means sold out for the dates: the response keeps the same shape with nulls, so parsing never branches on an error format.

price_stringstring

The total rate for the stay as Booking.com displays it: “US$2,434”.

pricenumber

The same rate as a plain number, for comparing quotes across markets or dates.

room_typestring

Which room the rate belongs to: compare like with like across markets.
