Endpoint
POSThttps://synapse-api-brown.vercel.app/api/bob/nft/floor-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call floor price lookup for a specific NFT collection contract address without committing to a subscription. Ideal for agents that need real-time or near-real-time NFT pricing data in an automated workflow, especially when multi-chain support across 57+ networks is needed and cost-per-query pricing is preferable over a flat subscription tier.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Contract address is valid but not an NFT contract — may return null or error
- Network unavailable or upstream NFT data provider down — service error
- Collection has no active listings — floor price may be null or zero
- Rate limiting or payment failure via x402 — 402 Payment Required response
