POSThttps://synapse-api-brown.vercel.app/api/mantle/nft/floor-priceWhen to prefer
Use this endpoint when you specifically need NFT floor price data on the Mantle blockchain. It is pay-per-call at $0.01 USDC via x402, making it cost-effective for spot lookups. Prefer this over general NFT APIs when targeting Mantle-specific collections, or when needing lightweight, fast on-demand floor price checks without a subscription.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Contract address exists on a different chain (not Mantle) causing no data found
- NFT collection has no active listings, making floor price unavailable
- Mantle network RPC downtime causing failed data retrieval
- Rate limiting or payment failure via x402 protocol returning 402 status
