Apps Free API for airfares

[alemito]

Hello

I'm looking for free API to get flight fares ... it seems that it is always necessary to be travel agents or affiliates (by paying a fee to have the key usage).

For example: Kayak no longer offers the API, their site has an HTTP GET request but is then blocked because it detects a connection from bot / robot (ie not via browser).
Skyscanner isn't free and provides API
Google Flights sounds interesting but sending via HTTP POST requires an MD5 digest that does not seem so easy to obtain via app

Do you have any suggestions or experience with this?

thank you very much

Maybe you can try scraping Google flights?

Using JSON in Google Flights | Nohup Technologies

Not sure what their terms are though...
