```nu
open urls.json | get urls | each { |u| http get $u } | to json

We can put this all together into a pipeline where we read data, manipulate it, and then send it back to the API. Lets `fetch` a post, `increment` the id, and `post` it back to the endpoint. In this particular example, the test endpoint gives back an arbitrary response which we can't actually mutate.

open urls.json | get urls | first | http get $in | upsert id {|item| $item.id | inc} | to json | http post https://jsonplaceholder.typicode.com/posts $in
