Nansen API
Nansen API provides programmatic access to Smart Money activity, wallet intelligence, token analytics, and other on-chain datasets across supported networks.
About this tool
Its Smart Money endpoints cover net flows, DEX trades, holdings, historical holdings, and selected strategy activity, with filters for Nansen's wallet labels. The wider API also includes address profiling and token-focused datasets for examining balances, counterparties, holders, flows, and market activity.
The API is suited to analysts, funds, trading and research teams, and applications that need structured on-chain intelligence instead of a dashboard-only workflow. Chain availability varies by endpoint across supported EVM and non-EVM networks, so integrations should check the official support matrix for each dataset.
