Privacy & Security

Your data, your control

The Subscription Pricing API serves publicly available pricing information. We do not collect, store, or process any personal data from your end users. API keys are hashed with SHA-256 and usage is tracked only for rate limiting and billing.

All payments are processed securely through Stripe. We never store card details.

FAQ

Common questions

What services do you cover?

We track 50+ subscription services across 12 categories including streaming video, music, news, productivity, gaming, VPN, fitness, food delivery, education, and communication. All with current Australian (AUD) pricing.

How fresh is the pricing data?

Every API response includes a last_verified date so you know exactly how current the data is. We verify prices regularly and update them as they change.

What is MCP?

Model Context Protocol (MCP) is the universal standard for connecting AI agents to external data sources. Our MCP server lets Claude, GPT, Gemini, and other AI models query pricing data directly.

Is there a free tier?

Yes. The free tier includes 100 API requests per day at no cost — enough to build and test your integration.

Do you convert currencies?

We store and return prices in their native currency (primarily AUD). We include the currency code in every response so your application can handle conversion if needed.

Can I use this for commercial projects?

Absolutely. Our Starter, Pro, and Enterprise tiers are designed for production use. Contact us for enterprise pricing and custom requirements.
