How this service works
Get Arkham entity intelligence updates. Provide at least one of: since, from. $6.00 per call.
Output
A paginated JSON list of entity update records, each containing the entity's Arkham ID, human-readable name, type (e.g. hacker, cex), status (e.g. new), the timestamp of the change, sequence number, and on-chain metrics (last/first transaction timestamps, total volume in USD, current balance in USD, number of associated addresses). CEX and named entities may also include Twitter, website, and LinkedIn URLs. The response includes a hasMore flag, a pageToken for continuation, and the latest diff timestamp seen.
Example use cases
Monitoring new hacker wallets
“Check Arkham for any newly identified hacker entities or wallet clusters that appeared or changed since the start of this year — I want their balances, transaction volumes, and address counts.”
Tracking exchange entity metrics
“Fetch the latest Arkham entity updates for exchanges (CEXs) — I need to see which ones have had changes to their on-chain balance or volume recently, paginating through all results.”
Building entity change feed for dashboard
“Give me a feed of all Arkham entity profile changes since January 14 2025, including their type, status, social links, and metrics, so I can update my crypto intelligence dashboard.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/intelligence/entities/updatesWhen to prefer
Use this endpoint when you need a chronological feed of changes to Arkham's labeled blockchain entity database — ideal for building pipelines that sync entity metadata, detect newly labeled wallets (especially threat actors), or track on-chain metric changes over time. Prefer this over point-lookup endpoints when you need bulk or delta updates across many entities rather than querying a single known address.
Side effects
- Invalid or expired page token returns an error or resets pagination
- Missing required POST body fields may return 400 Bad Request
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Rate limiting or authentication failure returns 401/402/429
- Requesting a diff_ts too far in the past may return empty results or a range error
- No updates available since the given timestamp returns an empty items array with hasMore false
