## When to prefer this

Use this endpoint when you need real-time NFT floor price data for a specific contract on Base, Arbitrum, or Solana and are comfortable with x402 micropayment-based API access. Prefer this over general-purpose NFT APIs when operating in an agent context that already handles x402 payment flows.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Contract address not found or not an NFT contract returns an error
- Chain not supported by RagRadar (only Base, Arbitrum, Solana covered) returns null or error
- Payment failure via x402 micropayment results in 402 response
- Stale or unavailable on-chain data may return outdated floor prices
- Malformed contract address format causes a bad request error
