“Can you check the floor price for the WorldChain NFT collection at contract address 0x4f5a2b8c9d3e1a7f6b0c2d4e8f9a1b3c5d7e9f01 and let me know what the cheapest available NFT is going for right now?”
Compare NFT investment options
“I'm considering buying into two WorldChain NFT projects — can you look up the floor prices for contracts 0xA1B2C3D4E5F6... and 0xF6E5D4C3B2A1... so I can see which collection is more affordable to enter?”

Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/worldchain/nft/floor-priceWhen to prefer
Use this endpoint when you specifically need NFT floor price data on the WorldChain blockchain. It is purpose-built for WorldChain and is well-suited for agents monitoring NFT collection prices, evaluating entry costs, or comparing collections on that specific chain. Prefer this over generic multi-chain NFT APIs when your use case is exclusively WorldChain-based and you want a simple per-call pay-as-you-go model via USDC.
Side effects
- Invalid or malformed contract address returns an error or empty result
- Contract address not found on WorldChain returns a not-found or null response
- Network or upstream data provider outage causes timeout or 5xx error
- Contract exists but has no active listings, resulting in null or zero floor price
- Payment failure via x402 protocol results in 402 response blocking the call
