Example: send a build request

Set LOT_API_KEY in your shell first. The response is written to obfuscated.luau.

curl -sS -X POST "https://obfuscation.lol/api/obfuscate" \
  -H "Authorization: ${LOT_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "source": "print(\"Hello from LOT\")",
    "node": "v4.8",
    "preset": "luau",
    "mutations": "normal",
    "cff": "normal",
    "if_bindings": "off",
    "add_debug_lib": false,
    "add_coroutine_lib": false,
    "rubis": false
  }' -o obfuscated.luau

Example: send a source file

With jq, read the file as a string and use the same endpoint:

jq -Rs '{
  source: .,
  node: "v4.8",
  preset: "luau",
  mutations: "normal",
  cff: "normal",
  if_bindings: "off"
}' input.luau | curl -sS -X POST "https://obfuscation.lol/api/obfuscate" \
  -H "Authorization: ${LOT_API_KEY}" \
  -H "Content-Type: application/json" \
  --data-binary @- -o obfuscated.luau
