AI prompt generator & optimisation API

The API rewrites a prompt to use fewer tokens, enforces a JSON schema on the output and improves answer quality without changing intent. Cost is the measurable part.

It works against OpenAI, Claude, Gemini, Llama and Mistral, so the same optimisation applies whichever model is behind the product.
