Is the SaaS Pricing API free?

Yes. The free tier serves newsletter, course and social tool pricing as JSON with no API key required, for prototype and non-commercial use with attribution. A Pro tier adds more categories, more tools, daily update feeds, and a commercial license.

Where does the pricing data come from?

Every price is read from the vendor's official pricing page and stamped with a verification date. No estimates or interpolation. If a tier isn't published, it isn't in the data.

Verified SaaS pricing data, as JSON

Fetch structured, current pricing for newsletter, course and social tools — the full official tiers, not just the teaser price. Every number is read from the vendor's pricing page and stamped with a verification date. Free tier, no key.

Data verified 2026-07-13.

Why this exists

SaaS pricing is a pain to track: it lives behind sliders, changes without notice, and every comparison article quotes a stale entry price. This API publishes the full tier curves in a clean, machine-readable format with a verification date — so your comparison page, calculator, or research tool doesn't have to re-scrape it. It's the data layer behind our own pricing calculators.
