# eth\_call - Ethereum

## How to Use the eth\_call Method

You will use this call frequently to read the data of blockchains with actual smart contracts but with no new publications. This call is not Ether-consuming.

The API has a limit of 1000% of the current gas limit for eth\_estimateGas and eth\_call methods to prevent abuse.

### Parameters

TRANSACTION CALL OBJECT \[necessary]

* from: 20 Bytes - the address where the transaction originated from.
* to: 20 Bytes - the address where the transaction is sent to.
* gas: \[variable] - the gas provided for the transaction execution (integer). eth\_call doesn’t consume gas, but some executions require stating this parameter.
* gasPrice: \[variable] the gasPrice applied for each paid gas (integer).
* value: \[variable] the value sent with a stated transaction
* data: \[variable] Hash of the method signature and encoded parameters. Check Ethereum Contract ABI for more details.

BLOCK PARAMETER \[necessary] - the string "latest", "earliest" or "pending", or an integer block number.

### What you receive

RETURN VALUE - the recalled value of the proceeded contract method.

    -d '{"jsonrpc":"2.0","method":"eth_call","params": [{"from": "0xb60e8dd61c5d32be8058bb8eb970870f07233155","to": "0xd46e8dd67c5d32be8058bb8eb970870f07244567","gas": "0x76c0","gasPrice": "0x9184e72a000","value": "0x9184e72a","data": "0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"}, "latest"],"id":1}'
```

{% endtab %}
{% endtabs %}

#### Outcome

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x"
}
```
