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 list of domain records, each containing the domain name, owning blockchain address, protocol details (id, title, docs URL, icon URL, supported TLDs, short name, description, and deployment base URL), and domain expiry date. Also includes next_page_params for pagination with page_size and page_token.
Example use cases
Resolve a crypto domain across chains
“Can you search Blockscout's multichain domain lookup for any domains matching 'alice.eth' across all chains in the mainnet cluster and tell me which address owns it and when it expires?”
Audit domain registrations by protocol
“Search for all blockchain domains with the name 'myproject' in cluster 'evm-cluster', filtering to Ethereum mainnet (chain_id 1), and list the protocol info and expiry dates for each result.”
Paginate through domain search results
“I was searching Blockscout for 'satoshi' domains across chains in cluster 'mainnet-cluster' and got a page token — can you fetch the next 5 results using that token?”
Technical details
Endpoint
GEThttps://api.blockscout.com/services/multichain/api/v1/clusters/%7Bcluster_id%7D/search/domainsWhen to prefer
Use this endpoint when you need to search for blockchain domain names (like ENS or similar naming protocols) across multiple chains simultaneously within a known Blockscout cluster. Prefer this over single-chain explorers when cross-chain domain resolution or discovery is needed. It is particularly suited for agents resolving human-readable names to wallet addresses across ecosystems, or auditing domain registrations by protocol.
Side effects
- Invalid or unknown cluster_id returns an error or empty result set
- Unsupported chain_id values may return no results
- Empty or overly generic query string 'q' returns too many results or times out
- Missing required cluster_id path parameter returns a 404 or bad request
- Expired page_token causes pagination to fail or restart
- Rate limiting or payment failure (x402) blocks the request
