Real-time DEX trading activity from Nansen-labeled smart money wallets across multiple chains.
What it does
This endpoint returns granular, transaction-level DEX trade data from wallets Nansen classifies as "smart money" — funds, smart traders (30D/90D/180D), and similar sophisticated participants. It covers the last 24 hours of activity and spans multiple chains including Ethereum, Solana, Base, BNB, Arbitrum, and more.
Each trade record includes the blockchain, timestamp, transaction hash, trader address and label, bought/sold token addresses and symbols, token amounts, token age in days, market cap, FDV, and estimated trade value in USD. Results can be filtered by smart money label type (Fund, Smart Trader, 30D/90D/180D Smart Trader), chain, trader address, token symbol/address, trade value range, token age, and market cap. Sorting is available on all returned fields. Pagination supports up to 1,000 records per page.
The endpoint is a POST request accepting a JSON body. It costs $0.05 per call via the x402 pay-per-request protocol, or 50 credits (free tier) / 5 credits (pro tier) when using a Nansen API key. Rate limits are enforced per-second and per-minute, reported in response headers.

Quality
Full OpenAPI 3.1 schema with detailed request/response models, clear pricing ($0.05/call via x402), comprehensive filter and sort enums, and a live 402 MPP challenge confirming the endpoint is operational. Minor deduction because no crawled documentation pages were available beyond the API root health check.
Warnings
- —No standalone documentation site was reachable (docs, pricing, README all returned 404); all information is derived from the OpenAPI spec.
- —Response schema references ($ref SmartMoneyDexTradesResponse) are defined but component details were inferred from the OpenAPI components section.
