I'd like to use the 0x api to swap tokens given on certains conditions included in a PHP file.
However, it seems 0x api/ecosystem revolves around JS since it has lots of utilities and needs npm to run.
Is there a workaround or do I need to port my PHP file to JS ?
The 0x swap API is completely HTTP based, so all you need is a way to send HTTP requests.
I believe PHP has built-in support for cURL, or you could use the built-in HTTP Client of a framework like Symfony or Laravel to perform your requests.
You're right that a lot of 0x, and indeed a lot of Web3 technologies, are built with JS. I might be easier for you in the long run to make the switch now.
