How this service works
**Beta — subject to breaking changes.** Token balances for a wallet address as of a historical snapshot date. Supports EVM chains (ethereum, base, bnb) and solana. Balances are computed from on-chain transfer history up to `as_of_date`. Results are ordered by USD value descending.
Output
A paginated snapshot of all token balances held by the specified wallet address on the given chain as of the requested date, powered by Nansen's 500M+ labeled address dataset. Excludes blacklisted addresses by default.
Example use cases
Example prompt
“Can you pull up the historical token balances for Ethereum wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 as of January 1st, 2024, using Nansen's profiler data?”
Technical details
Endpoint
GEThttps://api.nansen.ai/api/v1beta1/profiler/address/historical-token-balancesWhen to prefer
Use this endpoint when you need a point-in-time snapshot of a wallet's token holdings on a specific historical date, rather than current balances. Ideal for auditing smart money wallets, reconstructing portfolio states at specific dates, or analyzing how whale holdings evolved. Nansen's 500M+ labeled address dataset adds context that generic RPC node queries cannot provide.
Side effects
- Invalid wallet address format returns error (must be EVM hex or Solana base58)
- Unsupported chain identifier returns error
- Future date or malformed date string for as_of_date returns error
- Pagination parameters out of range return error
- Payment not received or insufficient USDC balance returns 402
- Rate limiting may occur with excessive requests
