## 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-monad-nft-sales-61d4857a -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need on-chain NFT sales data specifically from the Monad network, with fine-grained control over block range, sort order, and result count. Prefer it over general blockchain explorers when you need programmatic, pay-per-call access without subscription overhead, or when your use case is scoped to Monad NFT transactions.

## Known failure modes

- Invalid contract address format returns a validation error
- fromBlock greater than toBlock returns empty results or an error
- Requested block range not yet indexed returns no data
- Exceeding rate limits or missing payment (x402) returns 402 Payment Required
- Very large block ranges with high limits may time out or return partial data

## How this service works
