## When to prefer this

Use this endpoint when you need live, real-time NFT collection floor price and sales data for a specific contract address on a supported chain. It is ideal for monitoring collection activity, detecting sudden floor drops, or checking whether a collection has recent sales. Prefer this over static or cached NFT data sources when freshness matters.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Contract address not found or not an NFT collection returns empty or error response
- Rate limiting if called excessively without delay
- Unsupported chain returns 400 or null result
- Network timeout for slow RPC nodes on certain chains
