LLM APIs and Integration cookbook

Every tutorial uses a different SDK and I just want one call that actually works.

Hardcoded my key to test something quickly. Forgot to take it out before I pushed.

My script works fine in testing, then dies the moment I send more than a couple of requests in a row.

Blank screen for eight seconds, then the whole answer dumps out at once.

I'm passing the whole conversation back as one giant string and it feels wrong, but I don't know the right way.

Every time I add a new provider, I end up rewriting the same request in a different SDK with a different auth flow.

Why do I get a different answer every time, even at temperature zero?

I have no idea how much a feature costs until the invoice shows up at the end of the month.

Every provider has its own client, its own request shape, and its own error format, and I'm tired of writing the same logic three times.

Someone pasted a huge wall of text into my chat box. My next bill did not look like the others.

I don't want to burn API credit every time I run my test suite, but I still need it to catch real bugs.
