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 domain events, each containing an action type (e.g. registration, transfer, renewal), a timestamp, the originating address hash with optional ENS name, and the transaction hash on the specified chain.
Example use cases
Audit ENS domain ownership history
“Show me the full event history for 'uniswap.eth' on Ethereum chain 1 — I need to see every registration, transfer, and renewal that's ever happened on that domain.”
Monitor domain transfers on L2
“Can you check all the events for 'myproject.base.eth' on Base (chain ID 8453)? I want to know if it's been transferred or renewed recently, sorted newest first.”
Investigate suspicious domain activity
“Pull up the event log for 'exchange.eth' on Ethereum using Blockscout's BENS API — I'm trying to verify who originally registered it and whether it changed hands recently.”
Technical details
Endpoint
GEThttps://api.blockscout.com/services/bens/api/v1/%7Bchain_id%7D/domains/%7Bname%7D/eventsWhen to prefer
Use this endpoint when you need the historical event log (registrations, transfers, renewals) for a specific blockchain name service domain on a particular chain. It is distinct from general address/transaction search — it targets BENS (Blockscout's ENS-compatible name service) domain lifecycle events. Prefer it over generic blockchain explorers when you need structured, paginated domain event history across multiple chains from a single API.
Side effects
- Invalid chain_id returns empty results or 404
- Unknown or unregistered domain name returns empty items array
- Unsupported protocol_id causes no results
- Malformed domain name format returns error
- Rate limiting or payment failure returns 402 or 429
- Chain not supported by BENS returns empty or error response
