## 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-apechain-nft-by-owner-5846cce9 -d '<json body>'
```

Example prompt: Can you fetch all the NFTs owned by the wallet 0xABC123... on ApeChain and show me the first 20?

## When to prefer this

Use this endpoint when you specifically need to enumerate NFT holdings for a wallet address on the ApeChain network. Prefer this over generic multi-chain NFT APIs when ApeChain is the target and you want pay-per-call pricing without a subscription. Well-suited for lightweight, agent-driven queries where you only pay $0.01 USDC per lookup.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Missing required 'owner' field causes a bad request error
- Invalid pageKey results in no results or an error
- Rate limits or payment issues (x402) may block the call
- ApeChain node unavailability can cause timeouts or 5xx errors

## How this service works

## Output

Returns a list of NFTs owned by the specified wallet on ApeChain, including token metadata and a pagination key for retrieving subsequent pages if there are more results.
