**Parameters**

* `DATA`, 32 Bytes - hash of a block
* `params`: `["0x1d59ff54b1eb26b013ce3cb5fc9dab3705b415a67127a003c3e61eb445bb8df2"]`

**Returns**

`QUANTITY` - integer of the number of uncles in this block.

**Example**

```
// Request
curl -X POST https://rpc1.autheo.com -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_getUncleCountByBlockHash","params":["0x613aca96ec73b0c4395130088dd21c3813d923c7fe6a4650ae3ef30dbcd350e4"],"id":1}'
// Response
{"jsonrpc":"2.0","id":1,"result":"0x0"}
```

A result of 0x0 means that the block does not have uncle blocks.

## `eth_getUncleCountByBlockNumber`

Returns the number of uncles in a block from a block matching the given block number.

**Parameters**

* `QUANTITY|TAG` - integer of a block number, or the string "latest", "earliest", "pending", "safe" or "finalized", see the default block parameter
* `params`: `["0xe8", // 232] `

**Returns**

`QUANTITY` - integer of the number of uncles in this block.

**Example**

```
// Request
curl -X POST https://rpc1.autheo.com -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_getUncleCountByBlockNumber","params":["0xa8fa0"],"id":1}'
// Response
{"jsonrpc":"2.0","id":1,"result":"0x0"}
```

A result of 0x0 means that the block does not have uncle blocks.

## `eth_getUncleByBlockHashAndIndex`

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

**Parameters**

* `DATA`, 32 Bytes - The hash of a block.
* `QUANTITY` - The uncle's index position.
* `params`: `["0x1d59ff54b1eb26b013ce3cb5fc9dab3705b415a67127a003c3e61eb445bb8df2","0x0", // 0]`

```

**Result**

See `eth_getBlockByHash`.

Note: An uncle doesn't contain individual transactions.

## `eth_getUncleByBlockNumberAndIndex`

**Parameters**

* `QUANTITY|TAG` - a block number, or the string "earliest", "latest", "pending", "safe", "finalized", as in the default block parameter.
* `QUANTITY` - the uncle's index position.
* `params`: `["0x29c", // 668 "0x0", // 0]`

**Returns**

See `eth_getBlockByHash`.

Note: An uncle doesn't contain individual transactions.

**Example**

```
// Request
curl -X POST https://rpc1.autheo.com -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_getUncleByBlockNumberAndIndex","params":["0x29c", "0x0"],"id":1}'
```
