What it does
Nansen Web Searcher is an agent skill from nansen-ai/nansen-cli. 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.
Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Productivity & Automation, covering Web search and Smart contracts. The licence is MIT.
When your agent uses it
- You need current information
- Any web content to complement on-chain Nansen data
Example prompts
- “/nansen-web-searcher”
Requirements
- A credential in NANSEN_API_KEY
- Pre-approved tools (allowed-tools): Bash(nansen:*)
What it can do on your machine
Read from SKILL.md and the folder at commit d097942. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(nansen:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
NANSEN_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nansen Web Searcher loads about 551 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 194 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 3Positional 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.
