## 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-ethereum-nft-sales-3f9c81c1 -d '<json body>'
```

Example prompt: Pull the last 50 NFT sales for the Bored Ape Yacht Club contract (0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D) from block 18000000 to 19000000, sorted descending.

## When to prefer this

Use this endpoint when you need raw on-chain NFT sales data for Ethereum specifically, filtered by contract and block range. Prefer it over general blockchain explorers when you need programmatic, pay-per-call access without API key setup, or when querying historical sales in a precise block window for analytics or auditing purposes.

## Known failure modes

- Invalid or non-checksummed contract address returns an error
- fromBlock greater than toBlock causes invalid range error
- Block range too large may result in timeout or truncated results
- Non-NFT contract address returns empty results
- Payment failure (402) if x402 microtransaction is not completed
- Network congestion may slow response despite fast latency profile

## 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 paginated list of on-chain NFT sale events for the specified Ethereum contract, including sale transaction details, block numbers, and relevant metadata, ordered by the specified direction within the given block range.
