Parameters

NameTypeRequiredDefaultDescription
domain string required — Domain to check ranking history for (bare hostname, lowercased). Required, max 255 chars, no spaces.
keyword string required — Keyword to check ranking history for. Required, max 700 chars.
engine string optional "google" Optional, default "google". Same enum as /v1/search.
location any optional 2840 Google Ads geotarget ID, an ISO country code (e.g. "US"), or a country name. Optional, default 2840 (United States). Look one up with /v1/locations.
language string optional "en" ISO language code. Optional, default "en".
device string optional "desktop" One of: desktop, mobile. Optional, default "desktop".
date_from string optional — ISO YYYY-MM-DD, inclusive. Optional, default 730 days ago, which is as far back as the archive goes. An empty result is still a chargeable answer: coverage.observations counts the distinct days we archived this exact SERP in the window, so it can mean either "we observed you on N days and you never ranked" (observations > 0) or "we never looked" (observations: 0).
date_to string optional — ISO YYYY-MM-DD, inclusive. Optional, default today.
