# eth\_getUncleByBlockNumberAndIndex

Returns information about a uncle of a block by number and uncle index position.

## **Parameters**

1. `QUANTITY|TAG` - a block number, or the string `"earliest"`, `"latest"` or `"pending"`, as in the [default block parameter](https://ethereum.org/en/developers/docs/apis/json-rpc/#default-block).
2. `QUANTITY` - the uncle's index position.

## Returns

See [eth\_getBlockByHash](https://docs.noderpc.xyz/node-rpc/ethereum-api-endpoints/eth_getblockbyhash).

*NOTE:* An uncle doesn't contain individual transactions.
