## 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-nfts-by-owner-abstract-network-fe31ef9d -d '<json body>'
```

Example prompt: Can you pull up all the NFTs owned by wallet address 0xABC123... on the Abstract network? Show me up to 20 results.

## When to prefer this

Choose this endpoint when you specifically need NFT ownership data on the Abstract blockchain network and want paginated, pay-per-call access without a subscription. Prefer it over general multi-chain NFT APIs when Abstract is the target chain, and over free-tier endpoints when you need reliable throughput. Ideal for agents doing on-chain portfolio lookups, airdrop checks, or NFT gating logic on Abstract.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Unsupported network or wrong endpoint called — this is Abstract-specific, not multi-chain
- Invalid pageKey causes pagination failure or restart
- Exceeding rate limits results in HTTP 429 or payment-required (402) response
- Empty result set if wallet owns no NFTs on Abstract
- Network timeout or Vercel cold-start latency on first call

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns a list of NFTs owned by the specified wallet address on the Abstract network, including NFT metadata (token IDs, collection names, contract addresses, images, traits), along with a pagination key for retrieving additional results beyond the current page limit.
