Example prompt: Can you pull the recent sales summary for the NFT collection at address 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13d on Ethereum — I want to see the median sale price, how many sold, and which marketplaces they're trading on?

## When to prefer this

Use this endpoint when you need a quick, normalized summary of recent NFT collection sales activity including median price and marketplace breakdown, and can tolerate up to 24-hour cached data. Prefer this over real-time order-book APIs when a historical snapshot is sufficient and cost efficiency matters.

## Known failure modes

- Invalid or unrecognized chain identifier — 400 or empty result
- Collection address not found or no sales data available — empty sales array
- Unsupported chain — endpoint may return error or no data
- Cached data may be up to 24 hours stale — real-time price accuracy not guaranteed
- Rate limiting or payment failure via x402 protocol
