## 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-gnosis-nft-sales-0e4a4b65 -d '<json body>'
```

Example prompt: Pull up the last 50 NFT sales on Gnosis for contract 0xabc123... starting from block 30000000 to block 30500000, ordered from newest to oldest.

## When to prefer this

Choose this endpoint when you need historical NFT sales data specifically on the Gnosis blockchain, filterable by block range and contract. Prefer it over generic block explorers when you need structured, paginated sales event data without parsing raw logs. Best suited for analytics, monitoring, or audit tasks tied to specific Gnosis NFT contracts.

## Known failure modes

- Invalid contract address format returns an error or empty result
- fromBlock greater than toBlock returns no results or an error
- Very large block ranges may time out or hit rate limits
- Non-existent contract address returns empty sales array
- Payment failure via x402 protocol results in 402 response blocking data access
