Use this endpoint when you need on-chain ERC20 metadata — total supply, name, symbol, or decimals — for a token on Ethereum, Base, Arbitrum, Optimism, or Polygon, without needing price data or off-chain market information. Prefer this over CoinGecko-style endpoints when you have a contract address and need raw supply data directly from the contract.

- Unsupported chain ID returns an error
- RPC node unavailability causes timeout or 5xx error
- Malformed address format returns a 400 bad request
