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 array of quick search results matching the query on the specified chain, which may include addresses, tokens, transactions, smart contracts, and dapps with their relevant metadata such as names, hashes, types, and links.
Example use cases
Identify unknown contract address
“I have this contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — can you search Blockscout to tell me what it is, what token or protocol it belongs to?”
Find token by ticker on specific chain
“Search for the token USDC on Polygon using Blockscout and give me its contract address and any key details.”
Locate transaction by hash
“Can you look up transaction hash 0xabc123...def456 on Arbitrum in Blockscout and tell me if it went through and what it did?”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/search/quickWhen to prefer
Choose this endpoint when you need to quickly resolve an unknown identifier (address, token name, tx hash) on a specific blockchain without knowing exactly what type of entity it is. It is ideal for cross-entity searches where the type is ambiguous. Prefer it over chain-specific explorers when you need Blockscout's multichain coverage and programmatic access via a paid API with x402 payment protocol.
Side effects
- Invalid or unsupported chain_id returns an error or empty results
- Empty or overly broad query string returns no matches
- Query string matches nothing on the specified chain — returns empty array
- Payment of 0.0025 USDC not fulfilled — returns 402 Payment Required
- Network timeout or upstream Blockscout node unavailable
