Example use cases
NFT purchase budget check
“Before I buy an NFT, can you check the floor price for the Bored Ape Yacht Club collection at contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D so I know what I'd be paying at minimum?”
NFT portfolio valuation
“I hold NFTs from the Azuki collection at contract 0xED5AF388653567Af2F388E6224dC7C4b3241C544 — what's the current floor price so I can estimate my portfolio's minimum value?”
NFT market trend monitoring
“Can you pull the floor price for the Pudgy Penguins contract 0xBd3531dA5CF5857e7CfAA92426877b022e612cf8 on Ethereum so I can track whether it's gone up or down since yesterday?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/ethereum/nft/floor-price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, pay-per-call floor price lookup for an Ethereum NFT collection by contract address without committing to a subscription. Prefer this over general blockchain RPC calls when you need marketplace-aggregated floor pricing rather than raw on-chain transfer data.
Side effects
- Invalid or malformed contract address returns an error
- Contract address is not an NFT collection (ERC-721/ERC-1155) and cannot be priced
- Collection has no active listings, resulting in no floor price available
- Network congestion or upstream data latency may cause stale or delayed results
- Payment failure via x402 protocol blocks the request
