# nansen-web-searcher

Runs several search queries at once through the Serper API and returns titles, links and snippets. Useful when on-chain Nansen data needs fresh news or prices next to it.

## What it does

The skill wraps the `nansen web search` command. Queries go in as positional arguments or `--query` flags, and both forms combine: everything is searched in parallel. Each query returns 10 results by default, `--num-results` takes 1 to 20, and `--pretty` prints readable JSON.

The output is `results[]`, one entry per query, each holding `organic[]` with title, link, snippet and date, plus an optional `knowledge_graph`. Some domains never show up: paywalled and unfetchable sites such as bloomberg.com and twitter.com are excluded. For a specific URL there is `nansen web fetch`.

You need the `nansen` binary and a `NANSEN_API_KEY`, which takes precedence over a browser session. Run `nansen auth status` to check. If the selection turns anonymous or a renewal fails, the skill stops rather than falling back to anonymous x402 payment.

## Install

## When to use it
- pull fresh news on several coins in one call
- add market prices to on-chain Nansen data
- check what is being written about a token before reading transactions
- get links and snippets for a list of queries without searching by hand
- grab publication dates alongside titles and links

## Example prompts
- search the web for solana ecosystem news, 5 results per query
- run queries for "ethereum ETF" and "bitcoin ETF", 3 results each
- what's being written about bitcoin right now — add it to the 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 available in CLI 2.0.0 within the [macOS arm64 preview 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.

```bash
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.
