AI code generator — REST API & SQL generator

The API generates working scaffolding rather than snippets: NestJS or FastAPI service code, PostgreSQL schemas and Redis wiring.

Developers use it for the repetitive first hour of a service, not the interesting part.

ChatGPT API — GPT-4, o1 and o3 integration

One endpoint onto the OpenAI model family, including GPT-4 and the reasoning models, for chatbots, support automation and workflow tools.
