I am stuck with a problem of finding API for my project. The only purpose is to find all flights from the given airport on the given day. Anything working like “Anywhere” search on kiwi/skyscanner with specified airport and date (one-way).
As for budget, I can afford some 10$ for my own usage but it is not meant to be for deployment. Therefore I cannot afford some database subscriptions and other approaches designed for businesses.
While the problem not being directly related to hard-coding, I hope some of you have ideas what service to use.

I have tried aviasales API via travelpayouts, however it returns only one flight. Skyscanner offers partnership only for huge companies, other services provide tools with many internal logic such as round trips with many custom parameters and do not work with such simple use cases.
