How this service works
Get Arkham entity balance changes. $0.40 per call.
Output
An array of entity balance objects, each containing the entity ID, name, type (e.g. 'cex'), current total balance in USD and native units, previous balance in USD and native units, and a nested array of per-token balances (token ID, symbol, current and previous USD and unit balances).
Example use cases
Detecting exchange fund movements
“Check Arkham's entity balance data for Binance and tell me if their total crypto holdings have gone up or down since the last snapshot — I want to see the per-token breakdown too.”
Monitoring whale wallet holdings
“I want to track how much Bitcoin and Ethereum Coinbase holds right now versus before — pull the balance changes from Arkham so I can see if there's been any significant movement.”
Research on institutional crypto positions
“Can you get me a breakdown of FTX's token balances from Arkham, including what they held before, so I can compare current vs previous holdings across all tokens?”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/intelligence/entity-balance-changesWhen to prefer
Use this endpoint when you need to track balance changes for a named, labeled crypto entity (exchange, fund, whale wallet) identified by Arkham's intelligence graph — particularly when you want per-token USD and unit breakdowns with historical comparison. Prefer this over generic block explorers when you need entity-level attribution (e.g. 'Binance' rather than a raw address) and pre-computed USD valuations.
Side effects
- Unknown or invalid entity ID returns empty array or 404
- Payment failure via x402 results in 402 response and no data
- Rate limiting if too many requests in short period
- Stale data if on-chain indexing is lagged
- Entity with no tracked balances returns empty token balances array
