Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/sonic/nft/floor-price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time or near-real-time NFT floor price data specifically on the Sonic blockchain network. Prefer this over generic NFT APIs when the target collection is deployed on Sonic, and when pay-per-call pricing ($0.01 USDC) is more cost-effective than a subscription-based alternative. Ideal for agents making infrequent or on-demand floor price checks rather than continuous high-frequency polling.
Side effects
- Invalid or malformed contract address returns an error response
- Contract address not found on Sonic network returns null or not-found error
- Network congestion or RPC latency may delay response
- Payment failure via x402 results in 402 response before data is returned
- Contract exists but has no active listings, resulting in null floor price
