how to use APPLE WALLET API?

Hello there, i'm new in trying to use the apple wallet API.

we want to create passes to add identification credentials in the costumer's apple wallet.

but we have doubts, for example: is it mandatory to pay the apple developer memebership to use the examples of apple wallet api?

also, is there a way or an example of using this API in node.js?

Thanks for your attention, i will be waiting for your answers.
