Usage Tips

Querying Entity Balances

You can also pull balances for any labeled entity (e.g., Binance, Paradigm Fund) instead of raw wallet addresses.

• Provide exactly one of:

  • walletAddresses – array of addresses or

  • entityId – string name or UUID of the entity

• Leave the other field empty / omitted.

• All other parameters work exactly the same.

Example request of entity lookup

POST /api/beta/profiler/address/balances
Host: api.nansen.ai
apiKey: YOUR_API_KEY
Content-Type: application/json

{
  "parameters": {
    "chain": "all",
    "walletAddresses": [],
    "entityId": "Binance,
    "suspiciousFilter": "on"
  },
  "pagination": {
    "page": 1,
    "recordsPerPage": 100
  }
}

Querying Balances across all chains

You can also query balances across all chains using this

"chain": "all",
