## 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-celo-nft-sales-383aa265 -d '<json body>'
```

Example prompt: Pull the last 50 NFT sales on Celo for contract address 0xAbC123... from block 18000000 to 18500000, ordered by most recent first.

## When to prefer this

Use this endpoint when you need historical or recent NFT sales data specifically on the Celo blockchain, especially when you want to filter by a specific NFT contract address or a precise block range. Prefer this over generic blockchain explorers when you need structured, machine-readable output ready for agent consumption at low per-call cost.

## Known failure modes

- Invalid contract address format returns validation error
- fromBlock greater than toBlock returns empty result or error
- Block range too large may result in timeout or truncated response
- Network congestion on Celo may cause delayed responses
- Payment failure via x402 returns 402 status blocking access
