How this service works
Get the current floor price for an NFT collection across OpenSea + LooksRare (Ethereum). Returns per-marketplace floor (ETH), collection URL, retrieval timestamp, and the cheapest cross-marketplace floor with the marketplace tag. Use to price a collection without scraping marketplace UIs, or to detect cross-venue arbitrage gaps.
Output
Returns per-marketplace floor prices in ETH for OpenSea and LooksRare, the collection URLs for each, a retrieval timestamp, and a single cheapest cross-marketplace floor value tagged with the marketplace name.
Example use cases
Example prompt
“What's the cheapest floor price right now for the NFT collection at Ethereum contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D — check both OpenSea and LooksRare and tell me which marketplace is lowest.”
Technical details
Endpoint
POSThttps://agent402.tools/api/nft-floorWhen to prefer
Use this endpoint when you need real-time NFT floor prices aggregated across OpenSea and LooksRare on Ethereum in a single call, especially when you want the cheapest available entry price with marketplace attribution. Prefer this over single-marketplace lookups when comparative pricing matters.
Side effects
- Invalid or non-NFT contract address returns an error or empty results
- Non-Ethereum network requested for cross-marketplace floor (only Ethereum mainnet supported)
- Contract address not found on either marketplace returns null or zero floors
- Rate limiting or marketplace API outage may cause partial or failed responses
- Malformed 0x address format returns a validation error
