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.
About FastReact
FastReact is a FastAPI (Python) + React starter kit: auth, payments, multi-tenancy, and AI usage metering. Self-hosted, full source code, no lock-in. FastReact is the FastAPI + React foundation for production-ready apps, with authentication, billing, and AI usage metering built in. These failures wait until launch, when real money and your reputation are on the line. If checkout succeeds but the webhook never arrives, does the customer get what they paid for? These five are a glimpse; the full checklist is far longer and keeps growing.
