platform query parameter so you can pull the same metadata, keyword, and competitor data for either store.
platform defaults to apple, so existing iOS integrations keep working unchanged. Add platform=google to target Google Play.The platform parameter
App identifiers differ by store
Endpoints that take an app
:id validate it against the selected platform. Passing a numeric ID with platform=google (or a package name with platform=apple) returns INVALID_APP_ID.
The lang parameter (Google Play)
Google Play localizes content by language as well as country. Pass an optional lang (e.g. en, tr, de) on Google requests; it defaults to en. lang is ignored for Apple, which derives language from the storefront country.
country parameter uses ISO 3166-1 alpha-2 codes for both stores.
Cross-platform endpoints
These acceptplatform=apple or platform=google:
Apple-only endpoints
These rely on Apple-specific data sources or accounts and accept iOS apps only:- App Store Connect — your apps, versions, metadata, analytics, sales reports, reviews (Apple developer account)
- Apple Search Ads — campaign management (Apple Ads account)
- AI Visibility — AI-assistant recommendation tracking
- Advanced keyword insights —
keywords/visibility,keywords/movers,keywords/gap,keywords/demand-trend,keywords/suggestions/history,keywords/suggestions/emerging,apps/:id/keyword-clusters,keywords/expand - ASO —
aso/.../brief, intent clusters, metadata suggest/validate, competitor report
Google Play coverage for the advanced keyword-insight endpoints is on the roadmap. Until then, those endpoints return data for Apple apps only.
Notes on Google Play metrics
- Volume, difficulty, and opportunity scores are computed from Google Play-native signals (search results, ratings, review counts, autocomplete) using the same scoring core as Apple, so values are comparable across stores.
- Enrichment fields (
rankVolatility,marketDominance,historicalDays) are currently populated for Apple only. On Google these returnnullandinterpretation.trustworthyisfalseuntil enough historical rank data accumulates.
