Confused about how much I can use this API for free?

I'm going to be using this API at least ten times more than the graph shows below, but it worries me because I cant find anywhere in ESRI docs about how much you can use this API until it costs?

Andy Gup from Esri responded to a similar question a couple of weeks back: https://community.esri.com/t5/arcgis-api-for-javascript-questions/can-i-freely-use-this-api-in-an-io...

Is there any information about pricing when it goes above 2,000,000 tiles a month?

I wonder if the 'Pricing' tab at the top of the page (and linked in the post by Andy) might have some of the details you're looking for: https://developers.arcgis.com/pricing/  If not, you should reach out directly as Andy suggested.
