Answer 1

Using plumber 1.0.0, make them an array instead?

library(plumber)

#* @param a Enter your Website
#* @param b:[chr] Enter URLs
#* @param v The focused keyword
#* @get /something
function(a,b,v) {
  if (length(b) > 10) {
    stop("this api can handle at most 10 urls")
  }
  length(b)
}

#* @plumber
function(pr) {
  pr_set_api_spec(pr, function(spec) {
    spec$paths$`/something`$get$parameters[[2]]$schema$maxItems = 10
    spec
  })
  pr_set_debug(pr, TRUE)
}
