How this service works
ERC-20 token metadata on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base): name, symbol, decimals and totalSupply (raw + human), read live from contract state by address.
Output
Returns a JSON object with the token's name (e.g. 'USD Coin'), symbol (e.g. 'USDC'), decimals (e.g. 6), raw totalSupply (big integer string), and human-readable totalSupply (adjusted for decimals), all read live from the on-chain contract state.
Example use cases
Verify token supply before listing
“Before we list this new token on our platform, can you pull the live on-chain metadata for the contract at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon? I want to confirm the name, symbol, decimals, and total supply straight from the contract.”
Cross-chain token identity check
“I've got a contract address 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 that someone claims is USDC on Arbitrum — can you fetch the on-chain metadata and confirm the name and symbol match what they're saying?”
Calculate circulating supply for report
“I'm writing a report on a BNB Chain token at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d and need the human-readable total supply directly from the contract so my numbers are accurate and up to date.”

Endpoint
GEThttps://api.agentstools.dev/token/metaWhen to prefer
Use this endpoint when you need live, on-chain ERC-20 token metadata — name, symbol, decimals, and total supply — directly from contract state on Base, Ethereum, Arbitrum, Optimism, Polygon, or BNB Chain. Prefer this over off-chain token registries or price APIs when you need authoritative, real-time contract data rather than cached or aggregated information.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty metadata
- Unsupported network name returns a validation error
- Contract address with no deployed code returns an error
- Network congestion or RPC issues may cause timeouts
- Missing required 'token' query parameter returns a 400-level error
