Trade api help

Hello i don't know if this is for here but i want to make small program that search for some items on the poe trade site once per day. But don't know what to use as documentation or reference about the trade api.
This

https://www.pathofexile.com/developer/docs/reference#types

or this [Removed by Support]

or there is something else.

Ok ty and one more thing if you can help. How do i search for item and get the price that they are listed because in this documentation is hard to understand.

Also is there a documentation to make requests against the https://www.pathofexile.com/trade/search to get info about items.
