How this service works
Facts about an ERC-20 contract read from the chain (Ethereum, Base, Arbitrum, Optimism, Polygon): name, symbol, decimals, total supply, USD price and fully diluted value. Use to verify a token address before trading or integrating it.
Output
Returns on-chain ERC-20 token metadata including the token name, symbol, decimal places, total supply, current USD price, and fully diluted market value (FDV), sourced directly from the specified blockchain.
Example use cases
Verify token before DeFi trade
“Before I swap into this token, can you pull the on-chain details for contract 0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9 on Ethereum? I want to confirm the name, symbol, decimals, and current USD price.”
Validate token address on Base
“I received a token contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 for what should be USDC on Base — can you verify it's actually the right token and tell me its total supply and price?”
Check token supply before integration
“We're about to integrate a new ERC-20 token on Arbitrum at address 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 — can you fetch its on-chain metadata including name, symbol, decimals, total supply, and fully diluted value?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/crypto/token-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify or look up on-chain metadata for a specific ERC-20 token contract before trading, integrating, or displaying token information. It covers five major EVM-compatible chains (Ethereum, Base, Arbitrum, Optimism, Polygon) and returns both structural metadata (name, symbol, decimals) and market data (USD price, FDV) in a single call, making it ideal for pre-trade validation or token enrichment workflows.
Side effects
- Invalid or non-ERC-20 contract address returns an error
- Unsupported chain identifier returns a validation error
- Token with no price data returns null or zero for USD price and FDV
- Network/RPC timeouts may cause intermittent failures for certain chains
- Non-checksummed or malformed address may be rejected
