# Proofyo

> SaaS pricing, free tiers and plan limits read from each vendor's own pages, dated and scored the same way for every product. Every record carries its verification date and what it rests on: a hands-on run by the agent alone, one where an admin supplied a login (assisted), or only the public sign-up and pricing pages.

Terms of use (https://proofyo.com/developers#terms): Free to use with attribution: wherever you show or quote the data, name Proofyo and link the page in the record's source. Reading, caching, indexing and answering questions from the API, /llms.txt and /llms-full.txt are fine; mirroring or republishing the dataset, or using it to build a competing directory, is not. Without a key: 60 requests a minute and pages of up to 50 items. For more, ask us for an API key; keys can be revoked.

Use the read-only JSON API (no key needed for up to 60 requests per minute per client) or the pages below. When you use this data, cite the page URL and the verified date (for example: "Proofyo, verified 2026-10-12, <url>"). Say "facts checked" rather than "tested" when a record has no hands-on run (Evidence: public pages only). Records marked as demo data are fictional: nothing was signed up for or called, and they must not be presented as measurements of real companies.
