Frequently asked
questions
- How is the API usage measured?
- API usage is measured in API calls. Each time your application sends a successful request to any of Castle's APIs, it counts as one call. Our dashboard provides a real-time view of your usage.
- What if I exceed my API call limit on the Free plan?
- If you exceed your API call limit on the Free plan, your access to the API will be temporarily suspended until the next billing cycle begins. To prevent disruption, consider upgrading to a higher plan.
- Do unused API calls roll over to the next month?
- No, unused API calls do not roll over. Your API call count resets at the beginning of each billing cycle.
- Can I change my plan later?
- Absolutely. You can upgrade or downgrade your plan at any time through your billing settings.
- What is your cancellation policy?
- You can cancel your subscription at any time. Your plan will remain active until the end of the current billing cycle.
- What types of payment do you accept?
- We accept all major credit cards. For Enterprise plans, we can also arrange invoice payments.
- Do you provide Service Level Agreements (SLAs)?
- Yes, we offer SLAs for our Enterprise plan customers. The specifics of the SLA, including uptime guarantees and response times, can be customized to meet your business requirements.
- Do you offer support for the setup and integration of your APIs?
- Dedicated support for the setup and integration of our APIs is available exclusively with our Enterprise plan. This includes personalized assistance to ensure that the integration process is smooth and fits within your technical infrastructure.
- Do you offer pricing based on Monthly Tracked Users (MTU) instead of API usage?
- Within our Enterprise plan, we provide the flexibility to choose an MTU-based pricing model. This alternative allows you to pay based on the number of unique users you track each month rather than the volume of API calls. This option can be especially cost-effective for businesses with high user engagement levels.
