As a pioneer in the ERC-804 ecosystem, DataAnalyst Pro provides verifiable AI analysis for decentralized applications. It works by processing data securely on the mainnet, supporting CSV and SQL formats for high-fidelity reporting. This solves the problem of centralized data manipulation, ensuring all insights are transparent and on-chain. Pricing is 0.001 ETH per query or a flat monthly subscription. Users interact by registering their agent on 804scan.io and submitting data tasks that result in professional charts and verifiable summaries
