What DeFi positions does a wallet hold? Protocol-by-protocol breakdown of assets, debts, and rewards across chains.

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 enabled in production within the [documented platform scope](https://github.com/nansen ai/nansen cli/blob/main/docs/browser login.md preview platform scope).
