How this service works
Get Arkham predictions for an entity. $0.20 per call.
Output
A JSON array where each element contains the queried wallet address, the predicted entityID (e.g. 'binance', 'coinbase'), and the current USD balance held by that address. Enables rapid attribution of on-chain addresses to known real-world entities.
Example use cases
Identify exchange wallet ownership
“I have this wallet address 0xabc123... that just received a huge transfer — can you use Arkham to predict which entity owns it and what their total USD balance is?”
Due diligence on counterparty wallet
“Before we proceed with this OTC deal, can you run the counterparty's wallet address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e through Arkham and tell me which entity it's predicted to belong to?”
Monitor known exchange addresses
“Pull up Arkham's entity predictions for these five wallet addresses and tell me which ones are attributed to centralized exchanges and what their USD balances are.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/intelligence/entity-predictionsWhen to prefer
Choose this endpoint when you need programmatic, pay-per-request blockchain address attribution powered by Arkham's proprietary intelligence graph. It is preferable to generic on-chain lookup tools when you need entity-level labels (exchange, fund, whale) rather than raw transaction data, and when you want USD-denominated balance context alongside the attribution. Best for agents performing due diligence, compliance checks, or counterparty analysis on crypto wallet addresses.
Side effects
- Unknown or unattributed address returns empty entity prediction or null entityID
- Invalid address format causes 400 Bad Request
- Insufficient USDC balance for x402 pay-per-request triggers payment failure
- Rate limiting or API key authentication errors return 401/429
- Address with no on-chain activity may return zero USD balance with low-confidence prediction
