admin_datadir

Last updated:

`admin_datadir` returns the path of the directory where the backing node keeps its chain data and node-level state. It takes no parameters and returns a single string.

This method belongs to the `eth_peergraph` category and is restricted to the **Business** tier. It is an operational / introspection call — useful when you are correlating node identity and topology data (alongside `admin_nodeInfo` and `admin_peers`) rather than serving end-user requests. The returned path reflects the node serving your request and is informational only; you cannot use it to read files remotely.

Parameters

This method takes no parameters.

Returns

admin_datadir return value

  method: "POST",

  body: JSON.stringify({
  "id": 1,
  "method": "admin_datadir",
  "params": [],
  "jsonrpc": "2.0"
}),
});
const data = await res.json();
import requests
resp = requests.post("https://<your-endpoint>/", json={"id":1,"method":"admin_datadir","params":[],"jsonrpc":"2.0"})
