What APIs can be used?

All currently available APIs can be used with just one subscription. APIs added to APIstax in the future can be used at no additional cost.

Do I need to subscribe per API?

No, you only need one subscription to use all APIs.

Credits are used to simplify the billing of individual API calls. Each interface charges a certain number of credits. These are automatically deducted from your quota.

What happens to my credits in case of an error?

If a call cannot be executed due to a server-side error, nothing will be deducted from your credits.
