How this service works
Get Arkham unenriched transfers. Priced per row: $0.20 × limit (default 20, max 1650); pass the smallest useful limit.
Output
Returns a JSON object with a count of total matching transfers and an array of transfer records, each containing: transfer ID, type, chain, token ID, block hash, to/from address objects (with chain and address), token name and symbol, unit value, block number, historical USD value, token decimals, block timestamp, contract flags for sender/receiver, token contract address, and transaction hash.
Example use cases
Crypto portfolio transfer audit
“Get me all the raw token transfers in and out of wallet 0xc192c3570B18052faa4b7835Ad1d75591d4C55AC on Base — I need the token names, amounts in USD, and timestamps so I can audit the transaction history.”
On-chain DeFi flow monitoring
“Fetch the recent unenriched transfer records for USDC on the Base chain — I want to see the from/to addresses, block numbers, and historical USD values for the last batch of transfers.”
Blockchain forensics data pull
“I need to investigate transaction hash 0x32327b00bb8b4fe910758d72b08a24662e45b531779ff177e8d51130d1355d51 — can you pull the raw transfer record from Arkham including contract flags, token details, and the block it was confirmed in?”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/transfers/unenrichedWhen to prefer
Use this endpoint when you need raw, unprocessed blockchain transfer records without entity labeling or enrichment — ideal for forensic analysis, data pipelines, or cases where you want to apply your own entity resolution. Prefer this over enriched endpoints when you want lower latency, raw data, or when building your own analytics layer on top of Arkham's transfer data. The x402 pay-per-request model makes it cost-effective for sporadic or bursty queries without a subscription commitment.
Side effects
- Insufficient USDC payment via x402 returns payment required error
- Invalid wallet address format returns 400 bad request
- Unsupported chain identifier returns no results or error
- Rate limiting if too many requests are submitted in quick succession
- Empty result set if no transfers match the query filters
- Payment settlement failure due to network congestion or wallet issues
