Endpoint
POSThttps://phantom-api-omega.vercel.app/api/soneium/nft/floor-priceWhen to prefer
Choose this endpoint when you need real-time or near-real-time NFT floor price data specifically on the Soneium network. Prefer it over generic NFT APIs when Soneium coverage is required and pay-per-call pricing (rather than subscription) is acceptable.
Side effects
- Invalid or malformed contract address returns an error
- Contract address not found on Soneium network returns empty or 404
- Collection has no active listings so floor price is null or zero
- Network congestion may cause stale or delayed data
- Missing contractAddress field in request body causes validation error
