"synopsis": "Performs an HTTP GET request to the given URL, then invokes the callback with the response body.",
"codeBlocks": [
"extend(\"net\")\\n\\n# net:fetch usage\\nnet:fetch(\"https://example.com\", body => {\\n sput(body)\\n})\\n\\n# Partial usage is not applicable here. net:fetch expects exactly two arguments:\\n# 1) The URL\\n# 2) A callback function that receives the response body\\n\\n# Example callback that prints the length of the result\\nnet:fetch(\"https://example.org\", data => {\\n sput(string:concat(\"Length is \", string:to_string(array:length(data))))\\n})"
],
"notes": [
"The first argument must be a single string representing the URL.",
"The second argument must be a function (callback) that takes one argument (the response body as a single string).",
"net:fetch runs asynchronously, returning immediately with a boolean (true). The actual network request occurs in the background.",
"When the fetch completes, your callback is called with the raw response body. If the request fails, the callback receives a string describing the error."
