About Black
A black-box evaluation of how AI-generated tests find functional bugs in live APIs. The harder question is whether those tests find bugs. Each system receives only a JSON schema and one valid sample payload, then must generate API test cases that expose failures in a live reference API. The evaluation uses APIEval-20 v1.0, a black-box benchmark contributed by KushoAI. Because KushoAI is also one of the evaluated systems, this report includes the methodology, workflow definitions, repeated-run setup, and robustness checks so readers can understand where the performance difference comes from.

Screen thousands of scored companies, simulate portfolios, run backtests and get powerful AI insights. The thesis - you can beat the market without taking additional risk. The strategy is simple: high-quality companies at fair prices. The companies and figures shown here are illustrative examples, not live data or current Zen Scores.
