## 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-opbnb-nft-sales-2887eacb -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need fast, pay-per-call access to NFT sales data specifically on the opBNB (BNB Layer 2) network, with precise block-range filtering. It is well-suited for agents querying historical or recent on-chain NFT sale events without the overhead of a subscription plan, and when the target chain is opBNB rather than Ethereum mainnet, BNB Smart Chain, or other networks.

## Known failure modes

- Invalid contract address format returns an error or empty result
- fromBlock greater than toBlock results in no records or validation error
- Requesting a block range too large may time out or be rate-limited
- Invalid sort order enum value returns a 400-level error
- Payment not included or insufficient USDC triggers x402 payment-required response

## 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 list of NFT sale events from the opBNB chain, each record containing sale-related on-chain data such as transaction details, block numbers, buyer/seller information, token IDs, and sale prices, filtered according to the requested block range, contract address, sort order, and result limit.
