Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/arbitrum/nft/floor-priceWhen to prefer
Choose this endpoint when you need fast, pay-per-call NFT floor price data specifically on the Arbitrum network without committing to a subscription. It is ideal for agents that need occasional or event-driven floor price checks rather than continuous streaming. Prefer this over general blockchain explorers when you need structured, ready-to-use price data without parsing raw on-chain events.
Side effects
- Invalid or non-existent contract address returns an error or null result
- Contract exists but has no NFT listings, resulting in no floor price available
- Network congestion or RPC issues causing delayed or failed responses
- Contract address is on a different chain than Arbitrum, returning incorrect or no data
- Payment failure via x402 protocol blocks the request before execution
