Map Observer Public API

Free JSON endpoints for the data behind Map Observer’s trackers: confirmed and suspected algorithm updates, Map Pack volatility scores, and the Google Business Profile category list. No key, no signup, no rate-limit headers — just a link back to mapobserver.com wherever you use the data.

Terms (the short version)

  • Free for any use — dashboards, articles, internal tools, side projects.
  • Include a visible link to the relevant Map Observer page (we’ll list it in attribution.url on every response).
  • Don’t hammer it — endpoints are cached for 10–30 minutes; if you need more, email us.
  • We may rate-limit abusive clients at the edge.
