A: You have sharp eyes 😊 Let me address your use case in detail:

Building APIs
Yes, NoCode-X fully supports building APIs. You can create one-click CRUD APIs from your data format and customize them as needed. You can even generate APIs using AI. Authentication is built-in with an internal identity provider, and there are no limitations on the number of users.
Enterprise-grade features like Single Sign-On, JWT authentication, OAuth2.0, and OIDC1.0 are all included—just pick what works best for you!

Expose APIs under a Custom Domain and Create Documentation Automatically
Absolutely, you can expose your APIs under a custom domain (e.g., api.xxx.com). While the process isn’t as seamless as we’d like yet, we provide guidance to help you set it up.
For API documentation, you can leverage AI to create your own documentation. Fully automated API documentation generation is on our roadmap for the first semester of 2025.
You can track this feature here: https://docs.nocode-x.com/Roadmap.

Build a Rate Limiter
Yes, you can easily implement rate limiting in NoCode-X. You can count API calls, set thresholds, and enforce limits based on customer usage (e.g., stopping a customer after 1000 API calls per month).
This is straightforward to configure within the platform.

Build a SaaS App for Customers
NoCode-X is perfect for building robust, non-flashy SaaS applications for administrative tasks. Whether it’s for checking utilization, managing credits, billing, or payment info, the platform supports full-screen, tablet, or smartphone-friendly apps.
It includes features like tabs, graphs, synchronous/asynchronous calls, and more, all optimized for high performance and fast load times.
For billing, we also offer a full Stripe integration that you can use right out of the box.

CPU Minutes Usage
The 5000 CPU minutes are only consumed when someone actively uses your application. This includes API calls, webpage interactions, and logic executions.
However, during the development phase, CPU usage is negligible, and idle components or applications consume nothing.
For context, a single core with 1000 minutes can handle approximately 100,000 webpage calls, so you’ll be well-equipped to serve a large number of customers.
NoCode-X is an excellent choice for building SaaS applications with significant upselling potential. The platform’s cost structure allows you to maximize financial returns while delivering optimal value to your customers.

Additionally, enterprise-grade features like data classification, embedded security, custom domains, Single Sign-On, an integrated identity provider, strong auditing capabilities, and unlimited users are all included in your license—features that are often extra costs with competitors.

With NoCode-X, you get a full-featured platform ready to help you succeed!
