Example use cases
NFT portfolio floor tracking
“Can you check the floor price for the opBNB NFT collection at contract address 0x1234567890abcdef1234567890abcdef12345678? I want to know how much it costs to buy in right now.”
NFT arbitrage opportunity detection
“Look up the floor price for this opBNB NFT contract: 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef — I'm trying to figure out if there's a gap between what it's listed for and what I think it's worth.”
NFT collection due diligence
“Before I invest, can you pull the current floor price for the opBNB NFT project at contract 0xaabbccddeeff00112233445566778899aabbccdd so I can see how the market is valuing it?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/opbnb/nft/floor-priceWhen to prefer
Use this endpoint when you specifically need NFT floor price data on the opBNB network (BNB Chain's Layer 2). It is pay-per-call at $0.01 USDC via x402, making it cost-effective for spot queries. Prefer this over general NFT APIs when opBNB-specific data is required, and over full node RPC calls when you want a simple abstracted floor-price lookup without parsing raw marketplace events.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Contract address exists but has no active NFT listings, resulting in null floor price
- opBNB network congestion or RPC issues may cause timeouts
- Malformed contract address (wrong length or format) returns validation error
- Rate limiting or payment failure via x402 protocol returns 402 status
