Nansen Wallet Batch

Batch lookup wallet addresses against Nansen's profiler to filter for smart money and fund labels in one call. You'd use this when you have a list of addresses from onchain activity or a CSV dump and want to know which ones are worth paying attention to. The results come back with labels categorized by type (smart money, fund, social, behavioral), plus optional balance data if you need it. Invalid addresses don't crash the batch, they just return an error field you can skip. Straightforward way to separate signal from noise when you're staring at dozens of addresses.

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.
