How this service works
Get Arkham transfers for a transaction. $0.40 per call.
Output
Returns an array of transfer objects for the transaction, each containing: transfer ID, transfer type (token), chain, token name/symbol/address/decimals, block number, block hash, block timestamp, from and to addresses with Arkham entity and wallet labels (name, type, exchange attribution, Twitter, website), unit value, and historical USD value at time of block.
Example use cases
Trace exchange deposit attribution
“I have this transaction hash 0xf141a777ec5211657989b167d137dbc74f1a97984ba8ce3925bd640b78702587 — can you use Arkham to tell me which exchange the funds came from and which entity received them?”
Verify counterparty in USDC transfer
“Pull the Arkham transfer record for tx 0xf141a777ec5211657989b167d137dbc74f1a97984ba8ce3925bd640b78702587 and tell me whether either address is labeled as a known entity like Binance or Bitget.”
Reconstruct token flow for compliance
“I need to document a USDC transfer — fetch the full details for transaction hash 0xf141a777ec5211657989b167d137dbc74f1a97984ba8ce3925bd640b78702587 from Arkham including the token amount, USD value at block time, and any entity labels on the sender and receiver.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/transfers/txWhen to prefer
Use this endpoint when you need Arkham's proprietary entity intelligence layered on top of raw on-chain transfer data for a specific transaction — particularly when you need to identify which exchange, fund, or labeled wallet was involved. Prefer this over raw RPC calls or block explorers when entity attribution (who is behind the address) is required, not just raw transfer data.
Side effects
- Invalid or malformed transaction hash returns empty array or error
- Transaction not yet indexed by Arkham returns no results
- Insufficient USDC payment via x402 results in 402 Payment Required
- Transaction exists on an unsupported chain returns empty or error
- Rate limiting or payment failure causes 4xx response
