How this service works
On-chain ERC-20 token metadata (name, symbol, decimals, totalSupply)
Output
Returns the on-chain ERC-20 token metadata: human-readable name (e.g. 'USD Coin'), ticker symbol (e.g. 'USDC'), decimals (e.g. 6), and totalSupply as a raw integer from the blockchain contract.
Example use cases
Example prompt
“What are the name, symbol, decimals, and total supply for the ERC-20 token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48?”
Technical details
Endpoint
GEThttps://propeller.rocks/token/metadataWhen to prefer
Use this endpoint when you need authoritative on-chain ERC-20 token metadata directly from the contract rather than from a centralized token list or third-party API. Ideal for verifying token identity, normalizing token amounts using decimals, or resolving unknown contract addresses in DeFi workflows.
Side effects
- Contract address is not a valid ERC-20 token — returns error or missing fields
- Invalid or malformed contract address — returns 400-level error
- Contract deployed on unsupported chain — returns error
- Token contract lacks standard ERC-20 metadata methods — partial or empty response
