Ask the main part of your question in the title. This should be concise but informative.
Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.
Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.
Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

Some things to check:
For the first question, I would base my search on things like the extensiveness of the results, authentication, pricing, usability, etc. If you don't have any specific criteria right away, try making a few calls and playing with it to see if it will be what you needed. Some APIs I'll find its missing this one thing that makes another api a better choice. This is something you'll get better at with experience.
And no youre not expected to know all the tools, there are about an infinite out there. Generally youre expected to be familiar with some of the tools of the job but knowing more can't hurt either. Take things one thing at a time and make some simple project with what you've learned. That's how I do it anyways, but everyone is different.
I give up if there is no one tool but a million of them. Come back later and repeat.
Eventually just write it in python.
