Nansen
Onchain analytics platform with wallet labeling and smart-money tracking, offering an API with key-based and x402 access.
Overview
Nansen is an established onchain analytics platform that labels a large set of crypto wallets and surfaces smart-money flows, whale activity, and real-time alerts, with in-app trading. Its API offers direct HTTP access via API key or x402 micropayments. Wallet-label counts and assets-tracked figures are as reported by Nansen and should not be treated as independently verified.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 49 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.

This @HyperliquidX whale is sitting on ~$40M unrealized on a single $HYPE long. Entry at $38.68, +373% ROI. They've paid $2.83M in funding to hold this position and they're still holding. Over the last 15 days they've been moving $2-5M in USDC in and out of Coinbase repeatedly - managing around the position while keeping the core long intact.
