About this API
42matters bills itself as "Programmatic Access to App Market Intelligence" and is notable for the breadth of its platform coverage: 12 app stores (Google Play, Apple App Store, Tencent Appstore, Amazon AppStore, Huawei AppGallery, Roku Channel Store, Google TV, tvOS, Amazon Fire TV, Samsung TV, LG TV, Vizio). The API documentation groups endpoints into four buckets. App Details APIs include Lookup, App Download Estimates History, Monthly Active Users History, Reviews, Review Analysis, IAB Category for Apps, App-Ads.txt for Apps, App Changelog History, Ratings History, Country Availability, App Matching, Integrated SDKs, SKAdNetwork Attribution, App Store Optimization, Recrawl, and Enrichment. Search APIs cover Text Search, Search by Web Domain, Search by SDKs, Search by Permissions, Advanced Query, and Changelog Search. Daily Market Charts APIs provide Top Charts and App Rank History. Additional utilities include App Bundle Verifier and File Dumps. Authentication uses an API access token that must be passed with every request — explicitly documented. Pricing is not publicly disclosed; the pricing page is a product navigation hub with no tier names or prices, requiring a sales conversation. The free trial lasts 14 days with restricted endpoint and data access. No official SDK is offered beyond a Postman integration.
