Side effects
- Invalid or malformed contract address returns an error or empty result
- Contract address is not an NFT contract on Polygon — may return null or error
- Collection has no active listings, resulting in no floor price available
- Rate limiting or service unavailability returns a 5xx error
- Stale data if the underlying data source has not indexed recent sales
