admin_nodeInfo

Not available through Triport. admin_* is a node-management namespace and is not exposed by the service.

Not supported

admin_nodeInfo belongs to the node administration namespace (admin_*), which controls and inspects the internals of an individual Ethereum node (its identity, enode, peers, data directory). Triport is a multi-host routing service, not a single managed node, so these methods have no well-defined meaning across the pool and are not exposed.

Any request to an admin_*, personal_*, or engine_* method is rejected at the edge — it never reaches an upstream node — with a standard JSON-RPC error:

{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32601,
    "message": "admin namespace disabled"
  }
}

The HTTP status is 200; the rejection is carried in the JSON-RPC error envelope. Classification is case-insensitive (Admin_nodeInfo is rejected exactly like admin_nodeInfo). This matches the behaviour of every public Ethereum RPC provider — the admin namespace is disabled on production-facing endpoints.

What to use instead

• To learn which methods are routed and how the endpoint dispatches requests, see rpc-eth-transport.md.
• For chain and client metadata that is served, use standard read methods such as eth_chainId, net_version, eth_syncing, and web3_clientVersion.
• For mempool inspection, use the txpool_* methods (txpool_status, txpool_content, txpool_inspect).

See the shared errors page for the full error envelope.
