## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nansen-defi-holdings-cc727aef -d '<json body>'
```

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?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
