Nansen API pricing: Free, Pro, credits and x402
Checked Nov 6, 2026 on Nansen API’s official pages (sources below). Prices change often: confirm with the provider before you buy.
Nansen sells onchain analytics built on labeled wallets (Smart Money flows, wallet profiler, token god mode) through a REST API, an MCP server and a CLI. The API runs on credits: each endpoint costs a set number of credits per call.
Figures below are quoted from nansen.ai/api and the Nansen API Credits & Pricing Guide (docs.nansen.ai), both checked Nov 6, 2026.

How the Pro top-up works
Per Nansen’s docs, Pro is a top-up to a floor, not a recurring grant: on the 1st of each month, if your included credits are below 2,000 they are raised back to 2,000. Purchased credits are held separately, are spent after included credits, and never reduce the top-up. For agents that only need a few calls, Nansen’s x402 route lets you pay per request with no API key.
