How this service works
**Beta — subject to breaking changes.** Historical token screener data anchored to `to_date` over a `timeframe_days` window. Output columns match the production token screener API response shape exactly. When `trader_type='sm'` (or the deprecated `only_smart_money=True`), volume/netflow/nof_traders fields reflect smart money flows only. `sm_label_filter` is applied only in SM mode. `trader_type` overrides `only_smart_money` when both are set; only `all` and `sm` are supported. Use `exclude_sectors` to drop tokens whose sector tags include any of the listed sectors (e.g. `["Stablecoin"]`).
Output
A ranked list of tokens with historical smart money flow metrics, netflow figures, and associated metadata for the specified chains and date window, paginated and sorted by netflow descending by default.
Example use cases
Example prompt
“Using Nansen's token screener, show me which tokens had the highest smart money netflow on Ethereum over the last 14 days ending today, excluding blacklisted addresses and filtering to smart money traders only.”
Technical details
Endpoint
GEThttps://api.nansen.ai/api/v1beta1/token-screener/historicalWhen to prefer
Use this endpoint when you need historical (not real-time) token screener data filtered by smart money or labeled wallet activity across one or more blockchains. Prefer this over real-time endpoints when analyzing past windows or backtesting token selection based on Nansen's 500M+ labeled address intelligence.
Side effects
- Empty or missing 'chains' array returns a 400 validation error
- Invalid 'to_date' format causes a parsing error
- Unsupported chain identifier returns an empty result or error
- Conflicting trader_type and only_smart_money fields may produce unexpected filtering
- Overly broad queries with no filters may time out or return large paginated datasets
- Payment not fulfilled returns 402 Payment Required
