# Web Assembly Module APIs

Get the WebAssembly module (Wasm) `ZIP` bundle for a Spark service. This can be used to run Spark services locally.

## Reference by folder and service

> If using an API key, the API key group must contain user groups that are also assigned to \`Spark.GetNodegenZip.json\` or \`Spark.AllEncompassingProxy.json\`.
