Example code for the block json-rpc method. Сomplete guide on how to use block json-rpc in GetBlock.io Web3 documentation.

This method returns detailed information about a specific block on the NEAR blockchain. You can query a block by block ID (height), hash, and finality (e.g., final or optimistic).

## Supported Network

* Mainnet

## Parameters

| Parameter  | Type   | Required | Description                                                                                              |
| ---------- | ------ | -------- | -------------------------------------------------------------------------------------------------------- |
| `id`       | string | Optional | The height or hash of the block you want to query.                                                       |
| `finality` | string | Required | Specifies which finalized block to return. Acceptable values: `"final"`, `"optimistic"`, `"near-final"`. |
| `method`   | string | Required | Always set to `"block"`.                                                                                 |

## Use Cases

The `block` method can be used for:

* Track recently produced blocks and validators.
* Verify inclusion of transactions in a specific block.
* Monitor gas price and network performance.
* Retrieve block metadata for analytics or dashboards.

## Code Example

* **Node(Axios)**

```js
     import axios from "axios";
    let data = JSON.stringify({
      "jsonrpc": "2.0",
      "method": "block",
      "params": {
        "finality": "final"
      },
      "id": "17821130"
    });
    
    let config = {
      method: 'post',
      maxBodyLength: Infinity,
      url: 'https://shared.eu-central-1.getblock.io/<ACCESS_TOKEN>',
      headers: { 
        'Content-Type': 'application/json'
      },
      data : data
    };
    
    axios.request(config)
    .then((response) => {
      console.log(JSON.stringify(response.data));
    })
    .catch((error) => {
      console.log(error);
    });
```

* **Python(Requests)**

```python
   import requests
   import json
   
   url = "https://shared.eu-central-1.getblock.io/<ACCESS_TOKEN>"
   
   payload = json.dumps({
     "jsonrpc": "2.0",
     "method": "block",
     "params": {
       "finality": "final"
     },
     "id": "17821130"
   })
   headers = {
     'Content-Type': 'application/json'
   }
   
   response = requests.request("POST", url, headers=headers, data=payload)
   
   print(response.text)
```

## Error handling

| HTTP Code           | Error Message              | Description                                                                                                             |
| ------------------- | -------------------------- | ----------------------------------------------------------------------------------------------------------------------- |
| **400 Bad Request** | `REQUEST_VALIDATION_ERROR` | Failed parsing args: invalid type: null, expected string or map or expected one of `optimistic`, `near-final`, `final`. |
| **500**             | `Internal Server Error`    | Network issues.                                                                                                         |

## Integration with Web3

By integrating the `block` method into your NEAR Core API setup, developers can:

* Fetch live blockchain data for block explorers.
* Power validator dashboards with real-time metrics.
* Support analytics tools to visualise transaction throughput.
