## When to prefer this

Use this endpoint when you specifically need NFT ownership data on the Ink blockchain network. It is ideal for wallet portfolio lookups, NFT-gating checks, and paginating large NFT holdings. Prefer this over generic blockchain explorers when you need structured, programmatic NFT ownership data for Ink with pay-per-call pricing and no subscription required.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Non-existent wallet returns an empty NFT list
- pageKey from a different query context may cause unexpected results
- Exceeding rate limits or payment failure (x402) blocks the request
- Ink network downtime or RPC errors may cause timeouts

## How this service works

## Output
