Public plumber api

Posit Professional & Hosted Products Posit Cloud

hi,

I am new to the plumber package, but I would like to host an API posit cloud, which is available publicly.
The example is the one borrowed from the tutorial:

# plumber.R

#* Echo the parameter that was sent in
#* @param msg The message to echo back.
#* @get /echo
function(msg=""){
  list(msg = paste0("The message is: '", msg, "'"))
}

#* Plot out data from the iris dataset
#* @param spec If provided, filter the data to only this species (e.g. 'setosa')
#* @get /plot
#* @serializer png
function(spec){
  myData <- iris
  title <- "All Species"
  
  # Filter if the species was specified
  if (!missing(spec)){
    title <- paste0("Only the '", spec, "' Species")
    myData <- subset(iris, Species == spec)
  }
  
  plot(myData$Sepal.Length, myData$Petal.Length,
       main=title, xlab="Sepal Length", ylab="Petal Length")
}

I have set the hosted API to "All Posit Cloud Users".

Using in the Swagger, it looks to be fine, but if I call it in my local RStudio it results

jsonlite::read_json("https://8be29e0f39fa42c8a97a331c926fa35a.app.posit.cloud/echo?msg=yes")

Error in parse_con(txt, bigint_as_char) :
lexical error: invalid char in json text.

Isn't it possible to publish an API public with Posit Cloud, or just I make st wrong?
Thanks in advance,
M

Hello,

Unfortunately we do not yet support publicly available published content.

This means that you - or someone that you've shared it with - must be logged into Posit Cloud in order to successfully call the published API's endpoint. It's not working from your local RStudio environment because it is not authenticated.
