ChainScope Contract Inspect
x402
ChainScope Contract Inspect is a paid API for AI agents from chainsscope.duckdns.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).
Inspects a blockchain address to determine if it is a smart contract, returning token metadata such as name, symbol, decimals, and chain.

How this service works
Ethereum/Base only: is this address a contract, and if it looks like an ERC20 token, its name/symbol/decimals via eth_call -- skips the manual ABI-decoding work.
Output
Returns a JSON object containing the contract's human-readable name (e.g. 'USD Coin'), the chain it's on (e.g. 'ethereum'), its ticker symbol (e.g. 'USDC'), the full address, the number of decimal places, and a boolean is_contract flag confirming whether the address is a deployed smart contract.
Example use cases
Token contract validation before transfer
“Before I send funds, can you confirm that 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum is actually a smart contract and tell me its token symbol and how many decimals it uses?”
Unknown address classification
“I just received this address — 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum — can you tell me if it's a contract or just a wallet, and what token it represents if it is?”
Multi-chain contract metadata lookup
“What's the name and symbol of the token deployed at the contract address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v on Solana — is it actually a contract?”
Technical details
Endpoint
POSThttps://chainsscope.duckdns.org/tools/contract-inspectWhen to prefer
Choose this endpoint when you need to quickly classify a blockchain address as a smart contract versus an externally-owned account (wallet), and retrieve standardized token metadata (name, symbol, decimals) across Ethereum, Base, Bitcoin, or Solana — all through a single consistent interface. Prefer this over chain-specific SDKs or block explorers when you want a unified multi-chain API that returns structured JSON without managing separate RPC connections per chain.
Side effects
- Invalid or malformed address returns an error or null result
- Unsupported chain identifier causes a validation error
- Address is a wallet EOA — is_contract returns false with no token metadata
- Network timeout or RPC node unavailability causes a failed lookup
- Address exists but has no token metadata (non-token contract)
