Hi, looking for a flight price API with the highest number of price requests for free (no booking needed yet). I’m testing route optimization strategies which will result in lots of API calls. Kiwi’s doesn’t say if it limits? Any other suggestion?
We mostly work with GDSs. So, Amadeus suggests 2,000 free requests per month for low-fare search and 3,000 requests for a regular search, given that you use their self-service APIs. Sabre doesn’t have fixed rates and everything must be discussed individually.
As for other players, Skyscanner claims to provide all API services for free, if you can negotiate commercial partnership with them. Their limit is up to 100 requests per minute for live prices. You are right that Kiwi doesn’t provide open info on their rates, so it’s worth contacting them directly. The same for Travelfusion, Orbitz, and Priceline.
You can also try your luck with ATPCO, that’s where all flight prices come from.
