## 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 phantom-api-opbnb-nft-by-owner-6f3eaca1 -d '<json body>'
```

Example prompt: Can you pull up all the NFTs owned by wallet 0x1234abcd...5678 on the opBNB network? Show me up to 20 results.

## When to prefer this

Choose this endpoint when you specifically need NFT ownership data on the opBNB (Optimistic BNB) network. Prefer it over generic Ethereum or Polygon NFT lookups when the user's wallet or project is on opBNB. It supports pagination via pageKey, making it suitable for wallets with large NFT portfolios.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Wallet with no NFTs on opBNB returns an empty list
- Invalid pageKey causes pagination failure
- Rate limiting or payment issues result in 402 or 429 responses
- Network-specific errors if opBNB RPC is unavailable

## How this service works

## Output

Returns a paginated list of NFTs owned by the specified wallet address on the opBNB network, including token metadata such as token IDs, contract addresses, collection names, and a pagination key for retrieving subsequent pages.
