Endpoint
POSThttps://phantom-api-omega.vercel.app/api/base/nft/floor-price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time NFT floor price data specifically on the Base blockchain and want a simple pay-per-call model without a subscription. Prefer this over general NFT marketplaces APIs when you need programmatic on-chain access with micropayment billing via x402 protocol.

- Contract address exists but is not an NFT collection returns an error
- Network congestion or RPC issues may cause timeouts
- Payment of $0.01 USDC required per call via x402; missing or failed payment results in 402 response
- Contract on a different chain (not Base) may return no data
