## 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 omniapi-crypto-portfolio-endpoint-eb6830f0 -d '<json body>'
```

Example prompt: Can you pull up the full crypto portfolio for wallet address 0xABC123...def and show me all token holdings across all supported chains?

## When to prefer this

Choose this endpoint when you need to look up multi-chain crypto portfolio holdings for a wallet address in a single call, especially when paying per-call via x402/USDC is acceptable. Prefer this over single-chain block explorers when you need cross-chain aggregation without managing multiple RPC endpoints yourself.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Unsupported chain or asset may return empty or partial data
- Missing required 'query' field returns a 400-level validation error
- Payment failure via x402 (insufficient USDC) blocks the request
- Rate limiting or quota exceeded may return 402 or 429 errors
- Network congestion on queried chains may cause incomplete data
