## 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-zksync-nft-sales-75c6630e -d '<json body>'
```

Example prompt: Pull me the last 50 NFT sales on zkSync for contract 0xAbC123... sorted in descending order, from block 1000000 to 1050000.

## When to prefer this

Use this endpoint when you need historical or recent NFT sale event data specifically on the zkSync Layer 2 network, especially when filtering by block range or a specific NFT contract address. Prefer this over generic blockchain explorers when you need structured, programmatic access with pay-per-call pricing and no subscription required.

## Known failure modes

- Invalid or malformed contract address returns an error or empty result
- fromBlock greater than toBlock produces an invalid range error
- Limit value too large may result in timeout or truncated response
- Network congestion or node unavailability may cause delayed or failed responses
- Payment failure (x402) if insufficient USDC balance prevents the call
