## 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-bnb-nft-by-owner-56efae1d -d '<json body>'
```

Example prompt: Show me all the NFTs owned by the BNB wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — fetch up to 50 results.

## When to prefer this

Choose this endpoint when you need NFT holdings specifically on the BNB Smart Chain (BSC) for a given wallet address. It is ideal for building NFT portfolio views, auditing on-chain assets, or enriching user profiles with their BNB-chain NFT inventory. Prefer this over Ethereum or multi-chain NFT endpoints when the target network is specifically BNB/BSC.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Non-existent address returns an empty NFT list
- Exceeding rate limits or payment failure via x402 returns a 402 Payment Required error
- Missing required 'owner' field causes a validation error
- Invalid pageKey causes pagination to fail or restart from beginning
