Black vs Captchainbox

A black-box evaluation of how AI-generated tests find functional bugs in live APIs.

Set a price for unknown senders to reach your Gmail inbox. Trusted contacts get through normally, and you choose where 90% of the post-Stripe amount goes.

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.
