API
Free, read-only JSON access to everything this site displays, served straight from our cache, updated when the site updates. No key required. Research and information only; grades are measured checks, never ranking guarantees. Reviews are created on the website form only; this API never triggers a crawl.

Everything is served from our own database; this API never crawls target sites or calls upstream vendors. CORS is open for read-only use. Please keep request volumes reasonable; heavy users should cache responses. Start at /api/v1 for a machine-readable index of all endpoints.
