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.

Notes

Responses use this envelope:

{
  "data": [ { "domain": "example.com", "seo_score": 74, "seo_grade": "C",
              "aio_score": 61, "aio_grade": "D" } ],
  "meta": {
    "count": 1,
    "as_of": "2026-08-05T12:00:00Z",

  }
}

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.
