If you rephrase that to tools which deals with what the endpoints emits there is a boatload. Most emits JSON but XML can be found as well. Personally I use jaq. Gojq is nice as well. Both. Inspired by the original ja. You can find many lists[1]. I would especially point out jid[2] which often comes in handy to explore apis. Or if we stay at the http calling level and the command line: wget or fetch. If you include scripting languages then most http libraries will do. With Python a simple approach would be "python -m json.tool". [1] https://ilya-sher.org/2018/04/10/list-of-json-tools-for-command-line/ https://ilya-sher.org/2018/04/10/list-of-json-tools-for-comm...
