Nasca

AI applications often face challenges like unexpected high costs from heavy users, customer churn when limits are reached, and the complexity of building billing systems from scratch. Nasca addresses these by providing per-user spend controls, automatic top-up options, and upgrade prompts that convert blocked requests into paid conversions. The platform wraps existing AI function calls to enforce monthly, daily, or weekly limits based on user tiers. When thresholds are exceeded, it returns a custom error with a checkout link, allowing seamless credit purchases or plan upgrades processed through the developer's own Stripe account. Additional capabilities include revenue tracking dashboards, support for multiple AI providers, and low-latency checks that add minimal overhead. Plans start free for smaller user bases and scale with advanced analytics for growing applications.
