Example use cases
NFT collection sales analysis
“Get me the most recent 100 NFT sales for the zkSync collection at contract 0xDEADBEEF000000000000000000000000deadbeef, sorted newest first — I want to see what's been trading lately.”
Floor price trend monitoring
“Fetch NFT sales on zkSync from block 2000000 to 2100000 in ascending order so I can track how prices moved over that period for contract 0xABCDEF1234567890abcdef1234567890ABCDEF12.”
On-chain NFT arbitrage detection
“Give me the last 25 NFT sales on zkSync in descending block order — no contract filter, just everything across the network — so I can spot any arbitrage opportunities.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/zksync/nft/salesWhen to prefer
Use this endpoint when you need historical or recent NFT sale event data specifically on the zkSync Layer 2 network, especially when filtering by block range or a specific NFT contract address. Prefer this over generic blockchain explorers when you need structured, programmatic access with pay-per-call pricing and no subscription required.
Side effects
- Invalid or malformed contract address returns an error or empty result
- fromBlock greater than toBlock produces an invalid range error
- Limit value too large may result in timeout or truncated response
- Network congestion or node unavailability may cause delayed or failed responses
- Payment failure (x402) if insufficient USDC balance prevents the call
