## What it does

The skill runs `nansen research profiler batch` to inspect multiple wallet addresses across a specified blockchain. It collects label categories like `smart_money` or `fund` along with token balances. Invalid addresses do not crash the execution. Instead, the CLI provides an `.error` field for invalid entries, allowing the agent to skip broken addresses and proceed with valid ones. You can exclude the `balance` field to speed up lookups.

You need the `nansen-cli` package installed with the `nansen` executable ready. Before batch profiling, the agent checks authentication with `nansen auth status`. Authorization relies on the `NANSEN_API_KEY` variable or a browser session via `nansen login`. Without a valid API key or active session, the skill stops, because running research tasks anonymously is forbidden by the workflow.

Calls consume API credits or trigger x402 micropayments on HTTP 402 responses. Commands like `nansen account` and status checks never trigger automatic charges.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-wallet-batch -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/nansen-wallet-batch/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nansen-wallet-batch/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-wallet-batch -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/nansen-wallet-batch/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-wallet-batch -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/nansen-wallet-batch/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install nansen-ai/nansen-cli nansen-wallet-batch
```

2. **Manually: put the files in place**
- File: `.github/skills/nansen-wallet-batch/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-wallet-batch -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/nansen-ai/nansen-cli --path skills/nansen-wallet-batch
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/nansen-wallet-batch/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-wallet-batch -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- identify smart money wallets across a list of addresses
- detect investment funds on Ethereum in one batch request
- retrieve USD token balances for multiple crypto wallets
- filter out invalid wallet addresses without failing the batch job

## Example prompts
- Batch-profile these addresses on ethereum: `0xaddr1,0xaddr2` and keep smart money
- Run `nansen-wallet-batch` for my address list without balance data
- Find fund labels for the following wallet addresses using Nansen

## Authentication

Browser login requests `nansen:api` for API-key-equivalent account API permissions; existing OAuth/MCP `nansen:read` semantics and separate wallet authorization are unchanged.

Before any research command or loop, require an explicitly selected API key or saved browser session. Run `nansen auth status` first. Its cached/unverified metadata does not prove credential validity or unlocked storage. Cached access-token expiry alone does not mean the session is unusable: the CLI normally renews a selected session automatically during an already-authorized research task, without another consent request or a separate account check. Stop on anonymous selection, invalid authentication state, blocked or uncertain renewal/cleanup, or an actual authentication failure, including rejected or expired refresh authority. Follow the CLI error guidance; use the free `nansen account` check when troubleshooting calls for it. Do not unset a failed key, erase a session or switch to anonymous access to retry.

Use `nansen login` for fresh browser approval within the documented platform scope, or configure a conventional API key. `NANSEN_API_KEY` overrides the saved session. OpenClaw's optional `primaryEnv` mapping preserves configured API-key injection; it is not a required-key gate or proof of authentication. Normal credits and entitlements apply. Login does not purchase credits. 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).

API keys and browser sessions use the same automatic x402 payment behavior: a supported HTTP 402 challenge can spend funds from the configured wallet under existing wallet authorization, payment policy and spending limits. Each call, including calls in loops, can incur a payment. Authentication, authorization and session-renewal failures never trigger payment; login verification and `nansen account` never pay automatically. Anonymous x402 remains available as a separate paid workflow requiring explicit user intent and payment setup. Do not run this research workflow anonymously or switch to anonymous access after authentication fails.
