How this service works
Get Arkham address-tag association updates. Provide at least one of: since, from. $20.00 per call.
Output
A paginated JSON response containing a list of address tag change events, each with the blockchain address, chain, tag ID, tag name, tag category, status (new or deleted), timestamp of the change, optional entity name/type, and a pageToken for fetching the next page. A `hasMore` flag indicates whether additional pages exist.
Example use cases
Monitor newly identified DeFi wallets
“Check Arkham for any new address tags added on Arbitrum One in the last day — I want to know which wallets just got labeled and what category they fall into.”
Audit entity label removals
“Pull the Arkham tag update feed and show me any wallet addresses that had labels deleted recently, including the entity name and tag type that was removed.”
Enrich on-chain watchlist with fresh tags
“I have a watchlist of crypto addresses — can you check Arkham's latest tag updates to see if any of them have been newly identified or re-labeled with entity information?”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/intelligence/address-tags/updatesWhen to prefer
Use this endpoint when you need to track incremental changes to Arkham's address intelligence database — specifically which wallets have been newly tagged or had tags removed — rather than querying static tags for a known address. Prefer this for building surveillance pipelines, enriching watchlists with fresh labels, or detecting newly identified entities across supported blockchains.
Side effects
- Invalid or expired page token returns an error or resets pagination
- Unsupported chain identifier results in empty results or 400 error
- Missing or invalid x402 payment header causes 402 Payment Required response
- Rate limiting or payment failure interrupts paginated streaming
- No updates available for the requested time window returns empty items array
