Wallet Scoring API Comparison: Nansen vs Arkham vs WalletIQ (2026)

Need wallet intelligence for your dApp, airdrop, or compliance workflow? Here’s how the major providers compare.

---

The Problem

You’re building something that needs to understand wallets: an airdrop platform filtering bots, a compliance tool screening transactions, a DeFi protocol profiling users. You need structured data about any wallet address — fast, reliable, and affordable.

The options have historically been: pay enterprise prices (Nansen, Chainalysis), or scrape together free tools manually. WalletIQ fills the gap.

When to Use Each

Nansen — Best for: Enterprise analytics teams

If you have $100+/mo to spend and need the deepest wallet labels database with a full analytics dashboard. Great for research teams, hedge funds, and institutional analysts.

Arkham — Best for: Manual research

Free and great for one-off wallet investigations through the UI. But no API means you can’t integrate it into your product. Fine for researchers, not for developers.

WalletIQ — Best for: Developers building products

API-first, self-serve, affordable. Get structured wallet data in one API call. Perfect for airdrop platforms, compliance tools, wallet apps, and DeFi protocols that need programmatic wallet intelligence.
