How this service works
Read ERC-20 name, symbol, decimals, totalSupply (and optional holder balanceOf) via multicall3 on Base or Ethereum. 400 if the address is not a contract.
Output
Returns the token's name, symbol, decimals, and totalSupply read via multicall3. If a holder address is provided, also returns that holder's balanceOf balance. Returns HTTP 400 if the address is not a valid contract on the specified chain.
Example use cases
DeFi token due diligence check
“Can you look up the full metadata for the ERC-20 token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I need the name, symbol, decimals, and total supply.”
Wallet balance verification for token
“Check the balance of wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 for the ERC-20 token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum.”
Token contract identity resolution
“I have a contract address 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base — is it an ERC-20 token, and if so what's its symbol and how many decimals does it use?”
Technical details
Endpoint
POSThttps://grokzilla.shop/api/skills/erc20-meta?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain ERC-20 token metadata (name, symbol, decimals, totalSupply) or a holder balance on Base or Ethereum without setting up your own RPC node. It uses multicall3 to batch all reads in a single round-trip, making it faster and cheaper than sequential RPC calls. Prefer this over generic blockchain RPC tools when you want a clean JSON response with no Web3 library setup required, and when operating on Base or Ethereum mainnet specifically.
Side effects
- 400 Bad Request if the token address is not a deployed contract on the specified chain
- Invalid address format (must be 0x + 40 hex chars) will fail schema validation
- Contract exists but does not implement ERC-20 interface may return partial or empty results
- Network congestion on Base/Ethereum may cause timeouts
- Incorrect chain selection (e.g. token is on Ethereum but Base is specified) returns 400 or empty data
