How this service works
Get Arkham transfers with filters. Priced per row: $0.40 × limit (default 20, max 1650); pass the smallest useful limit.
Output
Returns a paginated list of on-chain transfer records including transaction hash, from/to addresses with Arkham entity labels, token name and symbol, USD value at time of transfer, block number and timestamp, chain, and total count of matching records.
Example use cases
Trace fund flows from a whale wallet
“Show me all outgoing transfers from the wallet 0xA304823C775d13fc851379C75e2b6f300E223234 on Ethereum and Polygon over the last week — I want to know which entities they're sending funds to and the USD value of each transfer.”
Monitor exchange inflows for a known entity
“Get me the 100 most recent transfers into Binance's deposit addresses across all chains using Arkham's intelligence data, so I can see who's been sending funds there.”
Investigate cross-chain token movements
“Use Arkham to look up all DAI transfers between ORIGIN-labeled addresses on Polygon — show me the transaction hashes, amounts in USD, and timestamps so I can build a timeline.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/transfersWhen to prefer
Choose this endpoint when you need detailed on-chain transfer history with Arkham's proprietary entity labeling (mapping raw addresses to named organizations, exchanges, or protocols). It is superior to raw blockchain explorers when you need to filter by entity name rather than raw address, or when you want USD-denominated historical values alongside transfer records across multiple chains in a single query.
Side effects
- Invalid or unrecognized wallet address format returns empty results
- Unsupported chain identifier causes filter to return no matches
- Exceeding the 1650 result limit silently caps the response
- Insufficient USDC balance for x402 payment causes request rejection
- Malformed body schema returns a 400 error
- Unknown entity name in from/to filter returns zero results
