Rate Limits

I have set up a Zapier to upload images on my Instagram page daily. Since I was uploading an image hourly, the API must’ve been exhausted. Or so I had thought. But after having waited for days (four), it still gives limit reached error. How long will this last, is this a bug, is there a fix, or am I toast? 

It seems that my Discord connections work for 3 minutes or less, then expire, through Zapier. And even when connected, there are throttling errors for a lot of functionality.Is Zapier dealing with this issue?

If we are using a Search Record, Update Record and Insert Record task on Salesforce in a single zap. So will that consume 3 API limit from salesforce or 1 limit ?

Is there a way to export app data code other than moving it to CLI? I am looking for a way to analyze and review the code in one place/format.    Also, can a developer create rate limits for zaps to keep the API traffic under control?   I appreciate the help!
