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 the token's name, symbol, number of decimals, and totalSupply in both raw on-chain units and human-readable (decimal-adjusted) form, read live from the contract state on the specified EVM network.
Example use cases
Example prompt
“What's the name, symbol, decimals, and total supply of the ERC-20 token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/token/meta?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need verified, live on-chain ERC-20 token metadata (name, symbol, decimals, totalSupply) for a specific contract address. Prefer this over cached or off-chain token registries when accuracy and freshness matter, or when the token is obscure and not listed on standard token lists. Ideal for DeFi agents that need to validate a token contract before executing swaps or transfers.
Side effects
- Invalid or non-ERC-20 contract address returns an error (contract may not implement name/symbol/decimals/totalSupply)
- Unsupported network value returns a validation error
- Contract address exists but is not an ERC-20 token (e.g. EOA or non-standard contract) causes a read failure
- Network RPC unavailable causes a timeout or service error
- Missing required 'token' query parameter returns a 400-level error
