## 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-kaia-nft-sales-a1841240 -d '<json body>'
```

Example prompt: Pull the last 50 NFT sales on the Kaia blockchain for contract address 0xAbC123... ordered from newest to oldest, covering blocks 12000000 to 12050000.

## When to prefer this

Use this endpoint when you specifically need NFT sales data on the Kaia blockchain (formerly Klaytn) and need fine-grained block-range filtering. Prefer this over general NFT APIs when you need pay-per-call pricing without subscription commitment, or when Kaia network coverage is required and your primary NFT data provider does not support it.

## Known failure modes

- Invalid contract address format returns an error
- fromBlock greater than toBlock yields empty or error response
- Limit value out of acceptable range may be rejected
- Block range spanning too many blocks may time out or be truncated
- Payment failure (x402) blocks the request entirely
- Network unavailability for Kaia RPC returns upstream error
