```

## When to prefer this

Use this endpoint when you specifically need NFT floor price data on the BOB blockchain network and want a lightweight, pay-per-call option without committing to a monthly subscription. Prefer this over general NFT APIs when BOB network coverage is required and cost control per query matters.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Contract address exists but has no NFT floor price data on BOB network
- Network unavailability or RPC node timeout causes request failure
- Malformed contract address string causes validation error
- Collection has zero listed NFTs resulting in null floor price

## How this service works

## Output

Returns the current floor price for the specified NFT collection, likely including the price value in the native currency or USDC, and potentially additional collection metadata such as currency denomination and recent sale context.
