Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/worldchain/nft/floor-priceWhen to prefer
Choose this endpoint when you need the NFT floor price specifically on the World Chain network. It is a pay-per-call endpoint ($0.01 USDC) with no subscription required, making it suitable for on-demand agent queries without managing API keys. Prefer this over general NFT aggregators when World Chain-specific data is required.
Side effects
- Invalid or malformed contract address returns an error
- Contract address exists on a different chain but not World Chain — returns no data
- Collection has no active listings, so no floor price is available
- Rate limiting or payment failure via x402 protocol returns 402 Payment Required
- Vercel cold start may add latency on first call
