## When to prefer this

Use this endpoint when you need the current floor price for a specific Base network NFT collection identified by its contract address. Prefer this over general NFT APIs when working specifically with Base-chain collections and needing real-time OpenSea/LooksRare data. Ideal for agents tracking NFT market conditions, portfolio valuations, or automated floor price alerts.

## Known failure modes

- Contract address not found or not a valid Base NFT collection — returns error or empty result
- Collection not listed on supported marketplaces (OpenSea/LooksRare) — no floor price available
- Invalid contract address format — returns validation error
- Network/Alchemy API timeout — service unavailable error
- Collection exists but has no active listings — floor price may be null or zero
