Pay-per-use Plans

The pay-per-use model differs fundamentally from the other account models.

The difference here is that the billing is not based on a fixed annual price but on your real API calls per month.

Minimum term is 1 month, cancellable at until 7 days before end of month and billing take place on a monthly basis by invoice for bank transfer.

All plans mentioned here have the same features and rate limit as a Professional Plus account.

All prices plus VAT

* The minimum charge per month is 1/12 of a “Professional Plus” account, 10 EUR gross / 8,40 EUR netto

The monthly invoice amount is calculated from the base charge plus the variable charge per 1,000 API calls multiplied by your API calls.

To find out which plan best suits your needs, here is a calculation sheet for you to play with.

With this model, you have one API key via which all API calls are made and all your API calls are charged.

At least 1/12 of the annual price of a “Professional Plus” account is charged monthly, currently 10 EUR. (The tipping point is abt. 15,000 API calls per day, from then on the invoice amount becomes larger than the minimum amount.)

It only makes sense to choose this model if you cannot manage with the rate limit of 600 calls/60 min. of a “Professional Plus” account.

With this model you have

• An Administration API key
• Unlimited number of Client API keys which are installed/connected to your clients, e.g. on distributed IOT devices

Billing model here is

• The administrative API key is charged with 1/12 of the annual price of a “Professional Plus” account.
• Only the client API keys are always charged from 1st API call.

With the Pay-per-use administration API you can manage your customers yourself.
