## 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 nft-portfolio-snapshot-agent402-tools-2bfd11c6 -d '<json body>'
```

Example prompt: Can you pull up a full NFT portfolio snapshot for wallet 0x742d35Cc6634C0532925a3b8D4C9B8a3e4b9fE12 — I want to see what NFTs they hold, their native ETH balance, and the current ETH price all at once?

## When to prefer this

Use this endpoint when you need a complete on-chain NFT portfolio snapshot in one round-trip — covering NFT holdings, native balance, and ETH price together. It is preferable to calling nft-holdings, wallet-balance, and crypto-price separately, saving latency and cost. Ideal for portfolio dashboards, wallet inspection tools, or any workflow that needs all three data points for a single address.

## Known failure modes

- Invalid or malformed wallet address returns a validation error
- Address with no NFT activity may return empty holdings array
- Network timeout from underlying NFT or price data providers
- Rate limiting or payment failure on the x402 payment layer
- Unsupported chain or non-EVM address format rejected

## How this service works

Bundled execution of the NFT portfolio workflow - NFT + wallet snapshot: NFT holdings, native balance, and ETH price for a given address in one call. One x402 payment runs 3 underlying tools (nft-holdings, wallet-balance, crypto-price); partial-success per step.

## Output

A bundled response containing the wallet's NFT holdings (collection names, token IDs, metadata), the native ETH balance for the address, and the current ETH/USD price — aggregating three underlying data sources (nft-holdings, wallet-balance, crypto-price) in a single response.
