How this service works
Total supply, name, symbol and decimals of an ERC-20 or ERC-721 contract, read on-chain. Use for market-cap math, supply checks and token due diligence.
Output
Returns the token's total supply (as a big integer or formatted number), human-readable name, ticker symbol, and decimal precision as read directly from the smart contract on the specified EVM chain.
Example use cases
Market cap math for DeFi token
“Fetch the total supply and decimals for the contract 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum so I can calculate its market cap.”
Token due diligence before investment
“I'm evaluating a new token at address 0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9 on Arbitrum — can you pull its name, symbol, total supply, and decimals from the blockchain?”
Verify NFT contract metadata
“Look up the name, symbol, and total supply for the ERC-721 contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/evm/total-supply?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, on-chain token metadata (supply, name, symbol, decimals) for ERC-20 or ERC-721 contracts on Ethereum, Base, Arbitrum, Optimism, or Polygon — especially for market cap calculations, supply verification, or token due diligence where accuracy from the chain itself is required rather than a cached off-chain source.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Unsupported chain name causes a validation error
- Token address that is not an ERC-20 or ERC-721 contract may return an error or zero values
- Network congestion or RPC issues may cause timeouts
- Payment of 0.002 USDC not provided results in HTTP 402 rejection
