How this service works
Get Arkham detailed transfer histogram. $0.80 per call.
Output
Returns a JSON array of time-bucketed objects, each containing a UTC timestamp ('time'), the aggregate USD value of transfers in that bucket ('usd'), and the number of individual transfers ('count'). The array is ordered chronologically, allowing reconstruction of a volume-over-time histogram.
Example use cases
Whale wallet activity spike detection
“Show me the transfer histogram for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 over the past 60 days — I want to see if there were any unusual spikes in USD volume or transaction count.”
DeFi fund cadence analysis
“Pull the Arkham transfer histogram for the Alameda Research entity over the last year so I can see how frequently they were moving funds and when the big USD flows happened.”
Portfolio on-chain activity audit
“Get me the transfer histogram for my tracked wallet over the past 30 days, bucketed by day — I want to understand how much USD volume and how many transfers happened in each period.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/transfers/histogramWhen to prefer
Use this endpoint when you need aggregated, time-series transfer data for a specific wallet or entity and want bucketed USD volume and count rather than individual transaction records. Prefer it for trend analysis, anomaly detection, and charting wallet activity cadence over time. It is ideal when you already have an address or Arkham entity ID and want to understand macro-level flow patterns rather than individual transfer details.
Side effects
- Invalid or unresolvable wallet address returns empty array or 404
- Time range too broad may result in very large response payload or timeout
- Malformed request body (missing required fields) returns 400 Bad Request
- Insufficient USDC balance for x402 payment results in 402 Payment Required
- Rate limiting or quota exceeded returns 429 Too Many Requests
- Unknown entity identifier returns empty result set rather than explicit error
