# FAQ: products, feeds and billing

Canonical URL: https://support.optiqube.ai/en/articles/products-feeds-and-billing

## How many products can I use?

You can connect several product sources. Credits depend on how many images you generate, not on how many products are in your catalog.

## How often is the product feed updated?

OptiQube reads your shop for prices, stock and new products: every hour if the shop has an active campaign or a live product group, otherwise once a day.

## Is there a free trial? What does it include?

Yes. Every new account starts with a trial of about 30 days and 1,000 credits, enough for about 25 images at 40 credits each. See [The free trial](https://support.optiqube.ai/en/articles/free-trial).

## Is there a monthly limit on images?

There is no limit on the number of images; you spend credits. Before every round you see what it costs and what you would have left. If you do not have enough credits, OptiQube shows how many you are short and offers **Upgrade plan** on the trial, or **Get credits** on a paid plan. See [How credits work](https://support.optiqube.ai/en/articles/how-credits-work).
