```sh
zero fetch --capability ragradar-nft-portfolio-tracker-6e71d300
```

Example prompt: Can you pull up the NFT portfolio for wallet address 0x4e83...3a2f on RagRadar and show me what collections they hold?

## When to prefer this

Use this endpoint when you need to inspect the NFT holdings of a specific wallet address across Base, Arbitrum, or Solana. Prefer this over generic blockchain explorers when you want AI-enriched portfolio analytics rather than raw transaction data, especially for multi-chain NFT tracking in a single call.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Address with no NFT holdings returns an empty portfolio
- Unsupported chain address format may return no results
- Rate limiting or payment failure (402) if USDC payment is not processed
- Network timeout if the on-chain data source is slow to respond

## How this service works
