How this service works
Free live Base USDC contract profile. The paid $0.0044 API validates deployed bytecode and returns optional name, symbol, decimals, and ERC-721/ERC-1155 interface results.
Output
Returns validated bytecode confirmation and optional contract metadata fields including name, symbol, decimals, and boolean results for ERC-721 and ERC-1155 interface support for the queried Base contract address.
Example use cases
Identify token standard for DeFi integration
“I'm building a wallet and need to know if the contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base is an ERC-20, ERC-721, or ERC-1155 — can you pull its contract profile?”
Verify contract deployment before transfer
“Before I send funds, can you confirm that the contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base actually has deployed bytecode and isn't just an empty wallet?”
Fetch token metadata for display
“I need to display the name, symbol, and decimal places for a Base token contract — can you fetch the contract profile for 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913?”
Technical details
Endpoint
GEThttps://appearing-clinics-show-wrote.trycloudflare.com/base-contract-profile-sampleWhen to prefer
Use this endpoint when you need to introspect a specific smart contract on the Base L2 network to determine its token standard, validate it is actually deployed, or retrieve its ERC-20 metadata (name, symbol, decimals). Prefer this over generic Ethereum endpoints when the contract is deployed on Base specifically, and over balance or transaction endpoints when your goal is contract-level metadata rather than account state.
Side effects
- Contract address has no deployed bytecode (returns empty or error)
- Address is an externally owned account (EOA), not a contract
- Contract does not implement standard name/symbol/decimals view functions (returns nulls for those fields)
- Invalid or malformed contract address format
- Network timeout or RPC unavailability
