Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/abstract/nft/floor-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call lookup of an NFT collection's floor price by contract address without committing to a subscription. Ideal for agents that need real-time or near-real-time floor price data across multiple blockchain networks. Prefer this over general NFT marketplace APIs when cost-per-call pricing and multi-chain support are priorities.
Side effects
- Invalid or malformed contract address returns an error or empty result
- Contract address for a non-NFT contract returns no floor price data
- Collection with no active listings may return null or zero floor price
- Rate limiting or payment failure may result in 402 or 429 errors
- Unsupported blockchain network may return an error
