# Quickstart

0xAPI gives developers fast, structured access to on-chain data across multiple networks.
Designed for reliability and ease of use, it offers targeted endpoints for core blockchain entities like:

* tokens,
* NFTs,
* transactions,
* blocks,
* wallets, and
* events

## Prerequisites

Before you begin, make sure you have:

* A registered [Ormi account](https://app.ormilabs.com)
* An [API key](/data-api/quickstart/generate-an-api-key)
* A REST client (e.g., curl, Postman, or any HTTP client)

## Get started

### **Step 1**: Identify the base URL

The base URL for all requests is:

```
https://api.data.ormilabs.com/
```

Each query starts with this base URL, followed by a specific endpoint path.

### **Step 2**: Add the endpoint path

For example, to fetch block data from Ethereum mainnet:

```
/v2/eth-mainnet/blocks
```

        Check out the API reference to find each endpoint's path.
      </p>
    </div>
  </a>
</div>

### **Step 3**: Include query parameters

Use query parameters to customize your request and narrow down the results.

Common examples include filtering by wallet address, limiting response size, or selecting specific block ranges.

```
?wallet_address=0x...&limit=20&from_block=10000000
```

</Frame>

Each endpoint supports its own parameter set - see the [API Reference](/api-reference/0xAPI/overview) for details.

### **Step 4**: Add authentication headers

```
Authorization: Bearer YOUR_API_KEY
```

### **Step 5**: Make the request

Use your REST client to send a GET request to the constructed URL.

Below is a minimal example using `curl`:

```
curl --request GET \
  --url https://api.data.ormilabs.com/v2/{chain_name}/blocks \
  --header 'Authorization: Bearer <token>'
```

Replace `<token>` with your API key and `{chain_name}` with the network you’re querying (ex. `eth-mainnet`).
