How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
Returns a JSON object containing the chain name, token contract address, an array of top holders (wallet addresses and their balances/percentages), the total number of unique holders, and a concentration object summarizing ownership distribution (e.g. Gini coefficient or top-N percentages).
Example use cases
Whale concentration check for new token
“I'm looking at investing in this new DeFi token — can you check the holder distribution for contract 0x6982508145454Ce325dDbE47a25d4ec3d2311933 on Ethereum and tell me if a few whales control most of the supply?”
On-chain due diligence before listing
“Before we list this Base token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on our platform, can you check how many holders it has and what the top holder concentration looks like?”
Monitor token decentralization over time
“Can you fetch the current holder count and top holders for the token at 0x912CE59144191C1204E64559FE8253a0e49E6548 on Ethereum so I can track whether ownership is becoming more or less concentrated?”
Technical details
Endpoint
GEThttps://klymax402.com/api/token-holders/api/holdersWhen to prefer
Use this endpoint when you need on-chain token holder analytics — specifically top holder rankings, total unique holder counts, and ownership concentration — for ERC-20 tokens on Ethereum or Base, without managing your own blockchain node or indexer. It's a good fit for DeFi due diligence, whale-watching, or decentralization analysis at $0.012/call with no API key required.
Side effects
- Invalid or non-existent contract address returns an error or empty holder list
- Unsupported chain value returns a validation error
- Contract address belongs to a non-ERC-20 contract, resulting in no holder data
- Rate limiting or payment failure (402) if USDC balance is insufficient
- Network-specific indexing delays may result in slightly stale holder data
