Yes. ZIPAPI is built to scale and optimized for commercial use. Flexible pricing makes it ideal for startups, or enterprise systems.
No. We don’t run artificial sales, discounts, or temporary price drops.
Our pricing reflects the real value and continuous improvement of our API. Customers joining today should pay the same fair price as early adopters – no penalties or pressure tactics.
The only exception is a permanent 25% discount on annual subscriptions, as a reward for long-term commitment.
Possibly – in case of inflation or rising infrastructure costs.
But: Existing customers will always keep their original pricing, as long as their subscription remains active.
“Simultaneous requests” refers to parallel API calls that are processed at the same time - not sequentially, but truly overlapping in execution.
Example: If a second request is made while the first is still being processed, both are considered simultaneous.
If your plan allows only 1 simultaneous request, the second one will be rejected with status code 429 - "Simultaneous request limit for current plan exceeded."
- The limitation applies per user account, not per API key.
- Speed of processing doesn’t matter - only the concurrent overlap does.
If your systems or users send multiple parallel API calls, we recommend a plan with a higher limit for simultaneous requests.
