How this service works
Get top Arkham counterparties for an address. $10.00 per call.
Output
A JSON object keyed by chain (e.g. 'bsc', 'base', 'ethereum'), each containing an array of counterparty records. Each record includes: the counterparty address, USD volume transacted, flow direction (in/out/all), transaction count, whether the address is a contract, Arkham entity metadata (name, type, social links), and any Arkham labels applied to the address.
Example use cases
Identify exchange interactions for a whale wallet
“Look up the top counterparties for crypto address 0xabc123...def on BSC — I want to know which exchanges or labeled entities it's been sending and receiving funds from, with USD amounts.”
Due diligence on a counterparty before a large transfer
“Before I do business with this wallet 0x31beec3942E4Faf3F253c86b51537387d16Ada34 on Base, can you pull its Arkham counterparty data so I can see who they've been transacting with and whether any known entities show up?”
Trace suspicious outflows from a flagged address
“I need to investigate where funds are going from address 0xD65448affe1475F101378A744a62C00F04CF50D6 — can you get me its counterparty breakdown showing top receivers, USD volume, and any entity labels like exchange names?”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/counterparties/address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need labeled, entity-resolved counterparty intelligence for a specific blockchain address — particularly when you want to know which named exchanges, funds, or protocols a wallet has interacted with. Prefer this over raw on-chain RPC calls when you need human-readable entity labels (e.g. 'Binance Cold Wallet') rather than raw addresses. Best suited for due diligence, compliance research, or on-chain forensics where Arkham's proprietary entity graph adds value over generic block explorers.
Side effects
- Payment not provided or insufficient USDC — x402 payment required before data is returned
- Invalid or malformed blockchain address — 400 error or empty result
- Address not found in Arkham database — empty counterparty arrays returned
- Unsupported chain specified — no data for that chain key in response
- Rate limiting or quota exceeded — HTTP 429
- Network timeout on large address history — truncated or partial response
