Example use cases
DeFi token due diligence
“Can you pull up the full details for the token at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum — name, symbol, decimals, total supply, and its current USD price?”
Portfolio balance check
“How much of the USDC token (0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) on Base does my wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 currently hold, and what's that worth in USD?”
Cross-chain token comparison
“Look up the token info for 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon and 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum — I want to compare their total supplies and current USD prices.”
Technical details
Endpoint
POSThttps://agent.maddegen.art/hub/api/v1/tools/erc20_info?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, on-chain ERC-20 token metadata (name, symbol, decimals, supply, USD price) or a specific wallet's token balance across any of 17 supported EVM chains. Prefer it over general blockchain explorers when you want a simple, structured JSON response without scraping. It covers a broad set of chains including newer ones like Berachain, Monad, HyperEVM, and Unichain that many competitors don't support.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty data
- Unsupported chain name returns a validation error (must be one of the 17 supported EVM chains)
- Token with no price feed returns null or zero for USD price
- Wallet address provided but not a valid EVM address causes a request error
- Network congestion or RPC issues may cause timeouts beyond the typical 120ms
- Token contract exists but has no on-chain metadata (name/symbol not implemented) may return partial data
