## 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).



# DeFi Exposure

**Answers:** "What DeFi positions does this wallet have across protocols?"

```bash
ADDR=<address>

nansen research portfolio defi --wallet $ADDR
# → protocol_name, chain, total_value_usd, total_assets_usd, total_debts_usd, total_rewards_usd, tokens

nansen research profiler balance --address $ADDR --chain ethereum
# → token_symbol, token_name, token_amount, value_usd per holding

nansen research profiler balance --address $ADDR --chain base
```

Combine DeFi positions (lending, LPs, staking) with spot balances for a complete picture of on-chain exposure.

Note: portfolio defi may return empty for wallets with no tracked DeFi positions.
