Nansen Holder Analysis
Quick way to check if a token's holder base is serious money or just retail gamblers. You get smart money holder ratios, flow breakdowns by wallet label (funds, whales, fresh wallets), and recent buyer quality data straight from Nansen. The flow intelligence endpoint is especially useful here. High fresh wallet inflows plus low smart money holders is your classic red flag. Works across major chains but note that it doesn't support native or wrapped tokens, so you need the actual token contract address. Requires a Nansen API key, which isn't cheap, but if you're already paying for it this beats clicking through their dashboard.

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.
