How this service works
ERC-20 token metadata
Output
Token metadata for the specified ERC-20 contract, including fields such as token name, symbol, decimals, and potentially other on-chain metadata attributes for the given contract on Base mainnet or Base Sepolia testnet.
Example use cases
Example prompt
“What are the name, symbol, and decimals for the ERC-20 token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base?”
Technical details
Endpoint
GEThttps://api.basefeed.io/v1/meta/tokenWhen to prefer
Use this endpoint when you need to look up ERC-20 token metadata (name, symbol, decimals) for a contract deployed specifically on Base mainnet or Base Sepolia testnet. Prefer this over general blockchain explorers when operating within an x402 micropayment-enabled agent workflow on the Base ecosystem.
Side effects
- Invalid or non-ERC-20 contract address returns error or empty metadata
- Contract address exists but is not an ERC-20 token results in missing fields
- Unsupported chain value (outside 'base' or 'base-sepolia') returns validation error
- Malformed address format causes 400-level error
- Payment failure via x402 protocol prevents request from proceeding
- Contract deployed on a different chain than specified returns not-found error
