# Explore Data in Cloud

> Run SQL queries against terabytes of indexed on-chain data

Chainbase Data Cloud is an online data warehouse for Web3. Run SQL queries against terabytes of indexed blockchain data — no infrastructure setup required.

## Quick Start

1. Go to [console.chainbase.com/dataCloud](https://console.chainbase.com/dataCloud)
2. Enter a SQL query:

```sql theme={null}
SELECT block_timestamp, block_number, _value, _from, _to
FROM ethereum.erc20_transfer
WHERE block_number = 17089970
```

3. Click **Execute** to see results instantly.

## Key Features

* **Unified datasets** — raw, decoded, and abstracted tables across 50+ chains
* **Parameterized queries** — use `{parameter}` placeholders for reusable templates
* **File Explorer** — save and organize your queries
* **Generate API** — turn any saved query into a REST endpoint with one click

## Generate an API from Your Query

After saving a query, click **Generate API** to create a callable endpoint:

```typescript theme={null}
const response = await fetch(
  `https://api.chainbasehq.com/v1/query/${queryId}/execute`,
  { method: "POST", headers: { "API-KEY": apiKey } }
);
```
