MCP agent does the heavy lifting
Tell your AI coding agent: "Set up a monthly Pro subscription with a 7-day trial." It creates the Google Play products, configures Pub/Sub, and maps entitlements. No console bouncing.
Server-side, zero client secrets
Your app never holds an API key. Verification happens on Tierux's servers — your backend gets a simple active/expired/grace response. No secrets to extract from your binary.
Any language, any backend
Plain REST API — POST to verify a purchase, GET to check an entitlement. Use Node, Python, Go, or whatever you already run. No SDK lock-in.
Free until 500 subscribers
Permanent free tier — unlimited apps, 1 paywall, server-side verification, no time limit. Pay only when you have real traction, and never a cut of your revenue.
Remote paywall config
Change pricing copy, layouts, and offers without an app release. Your SDK fetches the live config at runtime — iterate on your paywall without going through app review.
Set it and mostly forget it
RTDN webhooks and App Store notifications keep entitlement state current. Renewals, cancellations, grace periods — all handled server-side. Your backend just reads the API.
