How this service works
Get simplified DeFi holdings for a wallet address with aggregated tokens and protocol summaries in a user-friendly format.
Output
Returns a summary object with total_value_usd, total_assets_usd, total_debts_usd, total_rewards_usd, token_count, and protocol_count, plus a list of protocol-level holdings each containing chain, token positions (symbol, amount, USD value, position type: deposit/stake/borrow/mixed), and per-protocol asset/debt/reward totals.
Example use cases
Example prompt
“Can you pull up the DeFi holdings for wallet 0x4062b997279de7213731dbe00485722a26718892 — I want to see the total portfolio value, which protocols it's in, what's deposited vs borrowed, and any unclaimed rewards?”
Technical details
Endpoint
POSThttps://api.nansen.ai/api/v1/portfolio/defi-holdings?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a clean, aggregated view of a wallet's DeFi exposure across protocols and chains — especially for portfolio dashboards, smart money tracking, or risk assessment. Prefer over raw on-chain queries when you need protocol-level summaries, position type classification (deposit/stake/borrow), and USD valuations in a single call.
Side effects
- Invalid or malformed wallet address returns a 400 validation error
- Wallet address with no DeFi activity may return empty protocols array and zero values
- Unsupported chain or newly deployed contracts may be omitted from results
- Rate limiting or auth errors return 401/429 if API key is invalid or quota exceeded
- Truncated response schema may omit some fields for very large portfolios
