Point-in-Time Earnings Data API
Build a developer-focused API and dataset that delivers earnings calendars, reported metrics, amendment history, and exact publication timestamps in a backtest-safe format. The strongest need is not raw data alone, but confidence that users are not training on information that was unavailable at the time.
Warum das wichtig ist
You are trying to test whether earnings events help or hurt your strategy, but the harder problem is knowing whether your historical data matches what the market actually knew at the time. If a company revised a filing later, or if the event timestamp is wrong, your model can quietly learn from future information. Existing data sources may be cheap or accessible, but they rarely make amendment history and event timing easy to trust. As a result, you spend time stitching together feeds, checking edge cases, and still worry that your backtest is contaminated by leakage.
- · Entwickelt für Independent quants, small hedge funds, and systematic traders who backtest equity strategies using earnings or fundamentals..
- · Wahrscheinlichste Monetarisierung: SaaS subscription.

Differenzierung
Warum dies scheitern könnte
Selbstwiderlegung — das wichtigste Vertrauenssignal
- 1The economics may break if upstream data licensing is expensive or restrictive enough to kill margins.
- 2Advanced quants may prefer to buy directly from established vendors and build their own point-in-time pipeline.
- 3If validation is not rigorous and public, users will not trust the core claim of backtest safety.
Evidenzzusammenfassung
Wie KI diese Erkenntnis synthetisiert hat — keine wörtlichen Zitate
Multiple commenters focused on data quality rather than model architecture. Roughly four mentioned timing, amendments, survivorship bias, or publication-date correctness, while several others raised plain access and coverage concerns. The combination suggests a strong commercial opening for a trust-centric research data product rather than just another generic market data feed.
