DataHub
Dataset marketplace with on-chain access
Buy and sell datasets with on-chain access control (x402). List an asset, set a stablecoin price, and get paid 99% on every sale.
How it works
From listing to download in three steps.
Browse
Search the marketplace by category, format, and price. Every listing carries a schema preview so agents and humans know exactly what they buy.
Pay in stablecoins
One wallet approval settles the purchase on Solana through the x402 flow in USDC or USDT. Sellers keep 99%; the split is enforced on-chain, not by a middleman.
