Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/base/nft/floor-priceWhen to prefer
Use this endpoint when you specifically need floor price data for an NFT collection deployed on the Base blockchain and want a pay-per-call model with no subscription. Prefer this over general NFT APIs when cost efficiency per call matters and you are working in the Base ecosystem.
Side effects
- Invalid or non-existent contract address returns an error
- Contract address is on a different chain than Base, resulting in no data
- NFT collection has no active listings, so floor price may be zero or unavailable
- Rate limiting or payment failure via x402 protocol
- Network latency or third-party data source outage causing timeout
