# GraphQL Samples

ChainAnalytics provides GraphQL access to all data. You can start with GraphQL playground here:

{% embed url="<https://iotex-mainnet.chainanalytics.org/>" %}

You can try a very simple GraphQL query like

```
query {
 block(limit:1, where:{block_height:{_eq:1}}) {
   block_height,
  day,
  month,
  year
}
```

You will get the result like

```
{
  "data": {
    "block": [
      {
        "block_height": 1,
        "day": 22,
        "month": 4,
        "year": 2019
      }
    ]
  }
}
```

This is when the first block was created on IoTeX network.
