## 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-optimism-nft-sales-0faf4d86 -d '<json body>'
```

Example prompt: Pull the last 50 NFT sales on Optimism for contract 0xAbCd1234... sorted from newest to oldest, looking at blocks 110000000 through 111000000.

## When to prefer this

Choose this endpoint when you need indexed NFT sales data specifically on the Optimism L2 network and want to filter by block range or contract address. It is preferable over general blockchain RPC calls because it abstracts raw event log parsing, and preferable over Ethereum mainnet endpoints when your NFT collection is deployed on Optimism. Useful for analytics, auditing, and monitoring workflows where pay-per-call pricing is more economical than a subscription.

## Known failure modes

- Invalid or non-existent contract address returns empty results or an error
- fromBlock greater than toBlock causes a bad request error
- Limit value of 0 or negative integer may result in validation error
- Block range too large may cause timeout or truncated results
- Payment failure via x402 protocol returns 402 Payment Required before data is served

## 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
