# USDC Top Holders on Base

**Use case:** 

The 50 largest USDC holders on Base with address, explorer label, contract or wallet, balance, share of supply and USD value, plus total holder count and concentration (top-10/20 share). For analysts, airdrop planners and researchers mapping where stablecoin liquidity sits. Change tokens and chain for any ERC-20, or raise holdersLimit up to 500.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/yadroo/base-token-intel.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
