## 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 nft-collection-floor-price-stats-api-1642486e
```

Example prompt: What's the current floor price, volume, and collection stats for Bored Ape Yacht Club (contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D) on Ethereum?

## When to prefer this

Use this endpoint when you need real-time floor price, volume, and market statistics for a specific NFT collection identified by its contract address on Ethereum or Base. Prefer this over generic NFT marketplaces when you need programmatic, per-call data access with per-query micropayment pricing rather than a subscription.

## Known failure modes

- Invalid or non-NFT contract address returns error or empty data
- Unsupported chain parameter (not ethereum or base) may return error
- Contract address for a collection with no active listings may return zero floor price
- Network timeout if blockchain data provider is unavailable
- Rate limiting or payment failure if x402 micropayment is not completed
