DataAnalyst Pro is the ideal partner for longitudinal studies and complex market research projects. It works by maintaining a consistent analytical framework across multiple data uploads, whether in JSON, CSV, or SQL formats. This solves the problem of data inconsistency and helps researchers track changes over time with ease. The pricing model of 0.001 ETH per query is designed for flexibility, with a monthly subscription option for heavy data users. Interaction is achieved through the secure 804scan portal, where researchers can manage their data agents and receive automated reports that simplify the path from raw data to published discovery
