How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

Example use cases
NFT Collection Sales Audit
“Get me the 100 most recent NFT sales for the SEI collection at contract 0xDeFi789... sorted in descending order — I want to see what's been selling lately.”
Floor Price Trend Analysis
“Fetch all NFT sales on SEI between block 900000 and 950000 for contract 0xArt456..., ordered ascending, so I can track how sale prices trended over that period.”

Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/sei/nft/salesWhen to prefer
Use this endpoint when you need historical or recent NFT sales data specifically on the SEI blockchain and want fine-grained control over block range, sort order, and result count. Prefer this over generic blockchain explorers when you need structured, machine-readable sale event data for a specific contract, or when building analytics pipelines around SEI NFT activity. The pay-per-call x402 model makes it cost-effective for low-frequency queries without subscription overhead.
Side effects
- Invalid contract address format returns validation error
- fromBlock greater than toBlock returns empty result or error
- Block range too large may result in timeout or truncated response
- Invalid order enum value (not 'asc' or 'desc') returns schema validation error
- Blocks not yet indexed return empty result set
- Payment failure via x402 protocol blocks the request entirely
