How this service works
Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data
Output
Returns a JSON object containing the address hash, display name, coin balance, exchange rate, ENS domain name, contract status (is_contract, is_verified, proxy_type, creation_transaction_hash, creator_address_hash), reputation and scam flag, public/private/watchlist tags, associated token metadata, implementation contracts for proxies, has_logs, has_tokens, has_token_transfers, has_validated_blocks, has_beacon_chain_withdrawals, and the block number at which balance was last updated.
Example use cases
Scam address due diligence
“Before I interact with this address 0xAbCd1234...5678 on the Ethereum chain, can you check Blockscout to see if it's flagged as a scam, what its reputation score is, and whether it has any suspicious public tags?”
Smart contract deployment audit
“I need to audit the contract at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum — can you tell me if it's verified, who created it, what transaction deployed it, and if it's a proxy with any implementations?”
Wallet portfolio snapshot
“What's the coin balance and token holdings situation for the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on the Polygon chain right now? Also let me know its ENS domain name if it has one.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/addresses/%7Baddress_hash_param%7DWhen to prefer
Use this endpoint when you need comprehensive, structured metadata about a specific blockchain address — including contract verification, balance, tags, proxy info, and scam reputation — across any chain supported by Blockscout. Prefer this over generic RPC calls (eth_getCode, eth_getBalance) when you need enriched human-readable metadata, tags, ENS, and reputation signals rather than raw on-chain data. Ideal for due-diligence workflows, portfolio tools, and explorer-style lookups.
Side effects
- Invalid or malformed address_hash returns a 400 or empty result
- Unsupported or incorrect chain_id returns a 404 or chain-not-found error
- Address not indexed yet on the given chain returns minimal or empty data
- Rate limiting or payment failure (x402) returns a 402 Payment Required
- Network timeouts on heavily loaded chains may return 503
