How this service works
Get Address Counterparties Data
Output
A list of counterparty wallet addresses and entities that have transacted with the queried address, enriched with Nansen wallet labels, entity names, smart money tags, and interaction metadata such as transaction counts or volumes.
Example use cases
Example prompt
“Pull up all the counterparties for Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I want to see which wallets and labeled entities it has transacted with, especially any smart money or known exchange addresses.”
Technical details
Endpoint
GEThttps://api.nansen.ai/api/v1/profiler/address/counterpartiesWhen to prefer
Use this endpoint when you need to understand the social or transactional graph of a specific blockchain address — especially when you want Nansen's proprietary wallet labels and smart money classifications applied to counterparties. Prefer this over raw on-chain data tools when entity identification and labeling context matters.
Side effects
- Invalid or malformed blockchain address returns a 400 error
- Address has no on-chain transaction history returns empty counterparties list
- Unsupported blockchain network for the queried address
- Rate limiting or quota exceeded returns a 429 error
- Missing or invalid authentication token returns a 401 error
- Payment not received or insufficient balance returns a 402 error
