Get Started

In this guide we will learn how to use the events blueprint in insight.

• Create a project and navigate to the project settings to get a client ID
• Use insight API with the base URL below.
• To authenticate use your client ID in the x-client-id header or clientId query parameter

https://<chain-id>.insight.thirdweb.com

const getUsdtTransfers = async () => {
 try {
   const response = await fetch('https://1.insight.thirdweb.com/v1/events/0xdAC17F958D2ee523a2206206994597C13D831ec7/Transfer(address,address,uint256)?limit=5', {
    headers: {
      'x-client-id': <YOUR_THIRDWEB_CLIENT_ID>
    }
   });
   const transfersInfo = await response.json();
   return transfersInfo
 } catch (error) {
   console.error('Error:', error);
 }
};

Once you execute the query above you will receive a result similar to this:

Insight also supports querying multiple chains in a single API call. This is useful when you need to retrieve data across different networks without making separate requests.

const getMultichainTransfers = async () => {
 try {
   // Query USDT transfers on Ethereum (1) and Polygon (137)
   const response = await fetch('https://insight.thirdweb.com/v1/events?chain=1&chain=137&limit=10', {
    headers: {
      'x-client-id': <YOUR_THIRDWEB_CLIENT_ID>
    }
   });
   const transfersInfo = await response.json();
   return transfersInfo
 } catch (error) {
   console.error('Error:', error);
 }
};

When querying multiple chains, the response includes a chain_ids array in the metadata and each item in the data array includes its chain_id:

{
  "meta": {
    "chain_ids": [1, 137],
    "total_items": 10,
    "limit_per_chain": 5,
    "page": 0,
    "limit": 10,
    "total_pages": 1
  },
  "data": [
    {
      "chain_id": 1,
      "block_number": 14705663,
      // ... other Ethereum event data
    },
    {
      "chain_id": 137,
      "block_number": 25631042,
      // ... other Polygon event data
    }
    // ... more events from both chains
  ]
}

Key points about multichain queries:

• Use the base URL https://insight.thirdweb.com instead of the chain-specific subdomain
• Add multiple chain query parameters (e.g., chain=1&chain=137)
• The response includes a chain_ids array and limit_per_chain in the metadata
• Each item in the data array includes its chain_id for identification
