## 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.


# Wallet Profiler

All commands: `nansen research profiler <sub> [options]`

`--address` and `--chain` required for most commands.

## Balance & Identity

```bash
nansen research profiler balance --address <addr> --chain ethereum
nansen research profiler labels --address <addr> --chain ethereum
nansen research profiler search --query "Vitalik"
```

## PnL

```bash
nansen research profiler pnl --address <addr> --chain ethereum --days 30
nansen research profiler pnl-summary --address <addr> --chain ethereum
```

## Transactions & History

```bash
nansen research profiler transactions --address <addr> --chain ethereum --limit 20
nansen research profiler historical-balances --address <addr> --chain solana --days 30
```

## Relationships

```bash
nansen research profiler related-wallets --address <addr> --chain ethereum
nansen research profiler counterparties --address <addr> --chain ethereum --days 30

# Counterparties for up to 10 wallets in one call (max --days 90).
# Results are not aggregated — every row carries the wallet_address it belongs to.
# One ecosystem per request: EVM and Solana addresses cannot be mixed; `all` auto-detects it.
# --chain also takes any single chain the profiler serves, EVM or not: arbitrum, arc,
# avalanche, base, bitcoin, bnb (`bsc` is accepted too), ethereum, hyperevm, injective,
# iotaevm, linea, mantle, mantra, monad, near, optimism, plasma, polygon, robinhood, sei,
# solana, sonic, starknet, sui, ton, tron.
# Rows come back as contiguous per-wallet blocks ordered by wallet address, so a small page
# holds one wallet only — raise --limit and page with --page N to reach later wallets.
nansen research profiler counterparties-batch --addresses "0xabc,0xdef" --days 30 --limit 50
```

## Perps (no --chain)

```bash
nansen research profiler perp-positions --address <addr>
nansen research profiler perp-trades --address <addr> --days 7
```

## Batch, Trace & Compare

```bash
# Batch — profile multiple wallets at once
nansen research profiler batch \
  --addresses "0xabc,0xdef" --chain ethereum \
  --include labels,balance,pnl

# Trace — BFS multi-hop counterparty trace (makes N*width API calls)
nansen research profiler trace --address <addr> --chain ethereum --depth 2 --width 5

# Compare — shared counterparties and tokens between two wallets
nansen research profiler compare --addresses "0xabc,0xdef" --chain ethereum
```

## Flags

| Flag | Purpose |
|------|---------|
| `--address` | Wallet address (required) |
| `--chain` | Required except for perps and search |
| `--days` | Lookback period (default 30) |
| `--limit` | Number of results |
| `--addresses` | Comma-separated wallets for `batch`, `compare`, `counterparties-batch` |
| `--include` | Batch fields: `labels,balance,pnl` |
| `--depth` | Trace depth 1-5 (default 2) |
| `--width` | Trace width — keep low to save credits |
| `--fields` | Select specific fields |
| `--table` | Human-readable table output |
| `--format csv` | CSV export |

## Notes

- `pnl-summary` has no pagination support (returns aggregate stats, not a list).
- `perp-positions` has no pagination support.
- `labels` supports pagination — `--limit`/`--page` are honoured and the response is `{pagination: {page, per_page, is_last_page}, data[]: {label, category, kind[]}}`.
- `transactions` caps at per_page=100 (API limit).
- `trace` makes many API calls — use `--width` conservatively.
- `batch` accepts `--file <path>` with one address per line as alternative to `--addresses`.
