Thank you.  On mobile, the historic chart is hidden by default.  On desktop that should always be visible.  I think that has been the behavior for years.

I will see how popular this idea is with other users to add something to the url to display that chart by default on mobile.

This is something supported in Legendary subscriptions only at this time.

Are you referring to your collection export or the price list export?  The volume data is in the price list export already if you are a Legendary subscriber.

The API is intended for internal usage only.  The terms of use don't allow publishing the data for 3rd parties to see.  If you want to share the data you will need to contact us to discuss that more.

The API does cover all Pokemon cards in our database.  The linked page is not directly included in the API, but it can be easily derived from the API data.

What is Fire Stack?

I do not see a difference between those cards.

Can you let me know what the difference is between them?  I will work to fix this ASAP.

Thank you for this feedback.

Any particular type of figurines?  I'm guessing there are a ton of different kinds.
