Authentication

Nansen account API calls accept a selected nansen:api browser session or conventional API key with the same permissions. NANSEN_API_KEY takes precedence; optional primaryEnv preserves configured-key injection. Run nansen auth status for offline selection. Cached access expiry alone permits automatic renewal during an authorized task. Stop on anonymous selection, invalid state, blocked/uncertain renewal or actual auth failure; never drop a credential or fall back to anonymous x402 payment. Browser login does not grant wallet signing, privileged service identity or a persistent MCP integration key. Preserve all confirmation, signing, sanctions and geographic checks below. Browser login is available in CLI 2.0.0 within the macOS arm64 preview scope.

Web Search

Search the web for one or more queries in parallel via the Serper API.

nansen web search "bitcoin price"
nansen web search "solana ecosystem news" --num-results 5
nansen web search --query "ethereum ETF" --query "bitcoin ETF" --num-results 3

Positional args and --query flags can be combined — all become queries.

Flag	Values	Default	Purpose
`--query`	string	—	Query string (repeatable for multiple queries)
`--num-results`	1–20	10	Results per query
`--pretty`	flag	off	Human-readable JSON

Returns results[] — one entry per query, each with organic[] (title, link, snippet, date) and optional knowledge_graph.

Note: Some domains are excluded from results (paywalled/unfetchable sites like bloomberg.com, twitter.com). Use nansen web fetch to retrieve content from specific URLs.
