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 Emails. Done.
Transactional email for developers who do not care about email. Copy one prompt, wire the boring parts, and get password resets, verification, notifications and billing emails working. Code first, no templates to build and no infrastructure faff. App emails included Fair tiers for every stage Private by design Ready to send. Implement a public email API that handles everyday traffic but scales instantly when your app goes viral. Explain your sending use case to AWS and hope they approve it.
