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
A paginated JSON response containing an array of matching items (addresses, tokens, transactions, blocks, contracts, ENS domains, dapps, labels, user operations) relevant to the query, along with next_page_params for fetching additional results.
Example use cases
Token lookup across chains
“Search Blockscout on Polygon (chain ID 137) for a token called 'USDC' and give me the contract address and any matching tokens you find.”
Transaction hash investigation
“I have a transaction hash 0xabc123... and I need to know what it is — can you search for it on Arbitrum using Blockscout's multichain search?”
ENS domain resolution lookup
“Look up 'vitalik.eth' on Ethereum mainnet using Blockscout and tell me what address it resolves to and any related blockchain activity.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/searchWhen to prefer
Use this endpoint when you need to search across blockchain data (addresses, transactions, tokens, contracts, ENS names) on a specific chain supported by Blockscout, especially when you need a flexible keyword or identifier search rather than a direct structured lookup. Prefer this over chain-specific explorers when you want a unified API interface with consistent response format across multiple EVM-compatible networks.
Side effects
- Invalid or unsupported chain_id returns empty results or an error
- Empty or overly broad query string returns too many irrelevant results
- Malformed address or hash returns no matching items
- Rate limiting or payment failure (402) if USDC balance is insufficient
- Chain not indexed by Blockscout returns no results
- Pagination token mismatch causes unexpected result sets
