Output

Example use cases

Monitor exchange reserve changes
“Get me the time-series data for Coinbase's on-chain holdings from Arkham from the start of 2023 to end of Q2, so I can see how their ETH reserves changed month by month.”
Research DeFi protocol treasury

Technical details
Endpoint
POSThttps://api.arkm.com/x402/portfolio/time-series/entityWhen to prefer
Use this endpoint when you need historical, time-stamped portfolio data for a known, labeled blockchain entity (e.g. exchange, fund, protocol DAO) rather than a raw address. It is ideal for trend analysis, charting portfolio evolution, or comparing cross-chain holdings at specific points in time. Prefer Arkham over generic on-chain RPC queries when you need human-readable entity labels and aggregated multi-wallet, multi-chain portfolio views.
Side effects
- Unknown or unresolved entity name returns empty result or 404
- Date range outside available data returns empty time-series
- Insufficient USDC balance for x402 payment causes request to fail with 402
- Malformed entity identifier causes 400 bad request
- Rate limiting or throttling if too many requests are issued rapidly
