Getting Started

There are 3 primary developer tools for using the Cross-Chain Activity API:
 
1. Unified API - enterprise-grade endpoints to use with any programming language. Switch blockchains with one path parameter.

curl -X GET https://api.covalenthq.com/v1/address/demo.eth/activity/ \
    -H 'Content-Type: application/json' \
    -u YOUR_API_KEY:

 
2. Client SDKs - official client libraries for TypeScript, Go and Python.
 

import { CovalentClient } from "@covalenthq/client-sdk";

(async () => {
   const client = new CovalentClient("YOUR_API_KEY");
   try { 
    const chains = await client.BaseService.getAddressActivity("demo.eth");
    console.log(chains.data);
} catch (error) {
    console.log(error.message);
}
})();

 
3. GoldRush Kit - beautifully designed React components for your dApp frontend
