## How to call it through Zero

```sh
zero fetch --capability nft-collection-live-sales-feed-cb0f3f1a
```

Example prompt: Pull the most recent live sales for the NFT collection at contract address 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13d on Ethereum — I want fresh, normalized sale records, not cached data.

## When to prefer this

Use this endpoint when you need the freshest possible NFT sales data for a specific collection and chain, and stale cached data is unacceptable. Prefer this over cached endpoints when monitoring active markets, detecting price movements, or doing real-time scam/wash-trade analysis.

## Known failure modes

- Invalid or unsupported chain identifier returns an error or empty result
- Contract address not found or not an NFT collection returns empty or error
- Network/RPC issues cause fetch failure for live data
- Payment not accepted (x402 payment required, USDC 0.015)
- Rate limiting if called too frequently

## How this service works

Recent normalized sales — always fetched fresh

## Output

A list of recent normalized NFT sales for the specified collection and chain, fetched live (not cached), including sale prices, token IDs, timestamps, and buyer/seller details where available.
