​
1. Obtain an API Key

​
2. Use Your API Key to Make a Request

Once we have our API key, we can make requests to the API. Here’s a simple example of how to fetch the list of available assets: 
curl -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  https://api.blockworks.com/v1/assets

​
Example Response

Most API responses follow a consistent structure, with the data property containing an array of items, a total property indicating the total number of items, and a page property indicating the current page. 
{
  "data": [
    {

That’s it!
