A small Vercel-hosted microservice on the Base network that exposes a handful of protected endpoints: gated blog content and simple math utilities (addition and random-number generation). It’s useful for prototyping authenticated content gating, lightweight math microservices, and demoing API auth flows. Pricing is low and predictable (approx. $0.01–$0.10 per call), making it suitable for development, demos, and small production workloads.
