Before vs After FinFeedAPI
| Researchers needs | Before | After (with Flat Files S3 API) |
| Access to historical data | Data pulled through slow, rate-limited APIs or scraped manually. | Bulk access to historical OHLCV data via flat files. |
| Dataset preparation | Significant time spent cleaning, normalizing, and restructuring data. | Clean, consistent CSV files ready for analysis. |
| Handling large time ranges | Difficult to retrieve multi-year datasets without custom tooling. | Date-partitioned files make long-horizon studies easier. |
| Reproducibility of results | Hard to recreate exact datasets used in prior experiments. | Stable file paths and dates support reproducible research. |
| Integration with research tools | Custom ingestion scripts for each data source. | Works with standard S3 tools and SDKs already used in research. |
| Transparency of raw data | Abstracted APIs hide raw values and edge cases. | Direct access to raw CSV data makes assumptions visible. |
| Scalability of experiments | Data access becomes a bottleneck as scope grows. | Parallel downloads support large-scale experiments. |
| Time to analysis | More time spent fetching and fixing data than analyzing it. | Researchers can focus on analysis, not data plumbing. |
