Example use cases
Monitor new airdrop cluster tags

Track institutional brokerage address updates
“Fetch the latest Arkham tag updates and flag anything in the brokerage or institutional category that's been newly added or changed so I can update my compliance watchlist.”
Build a live on-chain intelligence feed
“Give me a paginated feed of all recent Arkham tag updates, starting from the beginning, so I can sync the latest wallet classifications into my internal database.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/intelligence/tags/updatesWhen to prefer
Use this endpoint when you need to stay current with Arkham's evolving on-chain address classification system — specifically to detect newly created tags or updates to existing ones. Prefer this over static address lookup endpoints when your goal is change detection or syncing a local copy of Arkham's tag database. It is the right choice for building intelligence pipelines that react to new entity classifications like airdrop clusters, exchange wallets, or brokerage addresses.
Side effects
- Invalid or expired page token returns an error or restarts pagination
- Payment failure via x402 protocol results in 402 response and no data returned
- Malformed POST body may result in 400 Bad Request
- Rate limiting if too many requests are made in rapid succession
- Empty result set if no tags have been updated since the last poll
