Search the web for one or more queries in parallel. Use when you need current information, news, prices, or any web content to complement on-chain Nansen data.

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 enabled in production within the [documented platform scope](https://github.com/nansen ai/nansen cli/blob/main/docs/browser login.md preview platform scope). Web Search Search the web for one or more queries in parallel via the Serper API. 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.
