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 API keys mentioned here have the same features and rate limit as a Professional Plus account.
Base price (monthly) | Price per 1,000 API calls | |
Advanced | 0 EUR | 0.025 EUR |
Ultimate | 10 EUR | 0.015 EUR |
Extreme | 25 EUR | 0.009 EUR |
Silver | 50 EUR | 0.008 EUR |
Gold | 120 EUR | 0.007 EUR |
Platinum | 200 EUR | 0.006 EUR |

Base price + Variable price * API calls count / 1,000
0.00 + 0.025 * 72,000 / 1000 = 1.80 EUR
> Less than than 1/12 Professional account, so 1/12 Professional account (10 EUR) will be charged
0.00 + 0.025 * 720,000 / 1000 = 18.00 EUR
1/12 Professional Plus + Base price + Variable price * API calls count / 1,000
10.00 + 0.00 + 0.025 * 720 / 1000 = 10.02 EUR
10.00 + 0.00 + 0.025 * 720,000 / 1000 = 28.00 EUR
