looking for api to article free software

I’m looking for software that can generate articles using OpenAI or DeepSeak API keys. I already have article titles ready and just need a tool to generate content based on my custom prompts. Ideally, it should automatically generate articles with a 5-10 minute interval between each one.

After researching, the closest option I found is the "WordPress Automatic Plugin – AI Content Generator and Auto Poster" by ValvePress, but it doesn’t quite meet my needs. I'm specifically looking for software that operates on a one-time payment model, rather than a credit-based system.
i need free open source, but can pay one time free also only if its good or good support.
i posted week ago but didnt get any good software response.

idk if you're okay with it or not,
but you can use wp automatic nulled version,
here's the latest version (clean):
