## When to prefer this

Use this endpoint when you need real-time NFT floor price data for a specific collection by contract address, especially across multiple chains supported by ChainRay. Prefer this over aggregator APIs when you need pay-per-request pricing without subscription commitments, or when operating in an x402 payment-enabled agent workflow.

## Known failure modes

- Invalid or non-NFT contract address returns an error or empty result
- Unsupported chain identifier returns a 400 or 404 error
- Contract address not found on the specified chain returns no data
- Rate limiting or payment failure returns a 402 Payment Required
- Network congestion may cause stale or delayed floor price data
