How this service works
Get Arkham historical data for an entity. $0.40 per call.
Output
Returns a JSON object keyed by blockchain name (e.g. 'bitcoin', 'ethereum'), each containing an array of time-stamped entries with a USD volume figure. Each entry has a 'usd' field (float) and a 'time' field (ISO 8601 timestamp), representing daily aggregated transaction volume for the queried entity on that chain.
Example use cases

“Get me the historical transaction history for Binance from Arkham — I want to see how their total daily Bitcoin and Ethereum USD volumes have shifted over the past year.”
Investigate fund activity before collapse
“Can you pull Arkham's entity transaction history for Three Arrows Capital? I want to see the daily on-chain USD volumes across Bitcoin and Ethereum leading up to their insolvency.”
Monitor whale entity for due diligence
“I'm doing due diligence on a DeFi protocol — pull the Arkham transaction history for Jump Trading to see their on-chain activity levels by chain and USD value over the last 6 months.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/history/entityWhen to prefer
Use this endpoint when you need time-series on-chain transaction volume data for a specific named entity (exchange, fund, wallet cluster) as tracked by Arkham Intelligence's entity labeling system. Prefer this over raw blockchain explorers when you need human-readable entity names rather than raw addresses, and when you want multi-chain aggregated USD volumes in a single call. Best suited for research, due diligence, or monitoring of well-known crypto organizations that Arkham has already labeled.
Side effects

- Invalid or missing API key — 401 unauthorized response
- Requested time range has no data — empty arrays returned per chain
- Network or rate limit error — 429 or 5xx response
