Nansen Prediction Markets
This gives you command-line access to Polymarket screeners through Nansen's API. You can pull trending events, sort markets by 24-hour volume or liquidity, search for specific questions like "bitcoin", and filter by status (open vs. resolved). It's solid for quickly scanning what's hot on prediction markets without opening a browser, or if you're building workflows that need to track volume spikes or new market creation. The sorting options are practical (volume_24hr, liquidity, open_interest, unique_traders_24h), and it defaults to active markets which is what you usually want. Requires a Nansen API key and installs via npm.

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.
