## When to prefer this

Choose this endpoint when you specifically need floor price data for an NFT collection deployed on the Berachain network. It is ideal for agents building Berachain-native NFT analytics, portfolio trackers, trading bots, or market intelligence tools. Prefer this over generic NFT APIs when Berachain is the target chain, as it is purpose-built for that network.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Contract address is on a different chain than Berachain, causing incorrect or null data
- NFT collection has no active listings, resulting in no floor price available
- Rate limiting or payment failure via x402 protocol if USDC payment is not processed
- Network latency or Berachain RPC downtime causing delayed or failed responses
