How this service works
Real-Time Base NFT Collection, Floor Price & Ownership Verification Oracle on Base Mainnet.
Output
Returns a JSON object containing the NFT collection's contract address, canonical name, total token supply, floor price denominated in ETH, and floor price converted to USD for the queried Base Mainnet collection.
Example use cases
NFT floor price alert system
“Check the floor price of the Basenames collection on Base mainnet and let me know if it's dropped below 0.01 ETH.”
Portfolio valuation for Base NFTs
“I hold some Base NFTs — can you look up the floor price in USD for the 'basenames' collection on Base mainnet so I can estimate what my holdings are worth?”
NFT collection research before purchase
“Before I buy into a Base NFT project, can you pull up the contract address, total supply, and current ETH floor price for the 'basenames' collection?”
Technical details
Endpoint
GEThttps://basenft-x402.vercel.app/v1/collectionWhen to prefer
Choose this endpoint when you need real-time NFT floor price and supply data specifically for collections deployed on Base Mainnet (Ethereum L2). It is ideal for agents doing NFT portfolio valuation, market monitoring, or pre-purchase research on Base. Prefer this over Ethereum mainnet NFT oracles when the target collection is Base-native, and over generic blockchain explorers when you need structured market data (floor price in ETH and USD) rather than raw on-chain data.
Side effects
- Unknown collection slug returns registry metadata only with market_data_available=false
- Invalid or unrecognized contract address returns identity_verified=false
- Network errors or Vercel cold starts may cause latency or timeouts
- Collections not in the local registry return limited metadata without verified identity
- Payment of $0.01 USDC required per call via x402 protocol; unpaid requests are rejected
