APIs have become core infrastructure. In the most recent State of the API Report by Postman, 46% of organizations said they planned to increase their investment in APIs over the next 12 months, and 82% have adopted some level of an API-first approach. The question for most teams is no longer whether to use APIs, but which ones, and for what.
For mobile teams, that question has a specific answer. App store data, whether that’s keyword rankings, download estimates, review feeds, or competitor benchmarks, is increasingly being pulled via API into dashboards, BI tools, and AI workflows rather than accessed manually through platform consoles. But not all app store APIs provide the same data, and choosing the wrong one means either missing the market view entirely or paying for capabilities you don’t need.
This article breaks down the top app store API tools available today, what data each one provides, and how to match the right API to your use case.
Key takeaways
- App store data APIs split into two categories: native APIs for your own apps, and third-party APIs for market-wide intelligence.
- The right API depends on your use case. Keyword tracking, competitor benchmarking, and market sizing all require a third-party tool.
- Third-party APIs with REST and MCP support let AI models and agents query app store data directly, making them increasingly useful for AI workflows.
- Connecting a third-party API like AppTweak to your App Store Connect or Google Play console gives you your own app’s performance data and market intelligence in one place.
- App store keyword rankings, competitor data, and category estimates are only available through third-party APIs, not native ones.
- Not all third-party APIs are built for ASO. Tools like Sensor Tower and Apptopia lean toward market sizing; AppTweak is built specifically for keyword, ad, and competitive intelligence.
What are the top API tools to get access to app store data?
The top API tools for app store data split into two groups: native APIs and third-party APIs. The native options are Apple’s App Store Connect API and the Google Play Developer API, which are built to manage and report on apps you own and operate. The leading third-party tools, which provide market-wide intelligence across any app, include AppTweak, Appfigures, Sensor Tower, Apptopia, and 42matters.
Some third-party tools, AppTweak included, also let you connect your own App Store Connect and Google Play consoles, so you get your apps’ performance data and market intelligence in one place. Which type you need depends on your use case, from managing your own apps to keyword tracking, competitor benchmarking, market research, and feeding app data into BI tools or AI workflows.
Native app store APIs
Native APIs are built to manage and report on the apps you own. The App Store Connect API returns your own app’s sales, proceeds, metadata, and performance data, and the Google Play Developer API does the same for publishing, performance, and monetization on Android.
App Store Connect API
The App Store Connect API automates management and reporting for your own App Store apps: uploading builds, updating metadata, managing in-app purchases and pricing, and pulling your own sales, downloads, and performance reports. Its strength is direct, first-party access to your account data, including metrics no third party can supply. Its limitation is scope: it covers only apps you own, returns no competitor or market data, and is built for app management rather than market research.
Google Play Developer API
The Google Play Developer API does the equivalent job for Android: managing publishing, releases, and monetization, and reporting on your own app’s performance. Its strength is authoritative, first-party Google Play data for apps you operate. Its limitation mirrors Apple’s: it is account-scoped, with no visibility into competitors, keywords, or the wider market.
Third-party app store API tools
Third-party APIs provide market-wide intelligence across apps you don’t own: keyword rankings, reviews, category trends, and download or revenue estimates. Because store-wide figures can’t be measured directly, these tools model them, so the numbers are estimated.
AppTweak API
AppTweak API gives you access to market-wide app store data covering keyword rankings, reviews, category rankings, download and revenue estimates, and ad intelligence such as paid keywords and share of voice, for any app across the App Store and Google Play in 100+ countries.
- Strength: 17 million keywords and 6 million apps dating back to 2014, plus exclusive data like historical keywords, featurings, and ad intelligence not commonly available via APIs. Connects via a standard REST API or an MCP server, which lets AI models and agents pull data directly. Connecting your own console adds your app’s performance data to the same view.
- Limitation: like all third-party tools, download and revenue figures are modeled estimates.
Appfigures API
The Appfigures API gives you your own apps’ sales, revenue, ratings, ranks, and reviews, and adds download and revenue estimates plus public data for any app through its Partner API add-on.
- Strength: unifies your own performance data and market estimates in one REST API.
- Limitation: estimates sit behind select plans and extra licensing, and public data carries resale restrictions.
Sensor Tower API
The Sensor Tower API, delivered through its Connect suite, provides download, revenue, and usage estimates, rankings, and ad intelligence for any app, with delivery via API, scheduled data feeds, or a Snowflake integration.
- Strength: enterprise-grade market and ad intelligence with flexible delivery into BI and warehouse tools.
- Limitation: enterprise-priced with no self-serve sign-up, and all figures are modeled estimates.
Apptopia API
The Apptopia API returns download, revenue, and usage estimates alongside SDK intelligence and roughly 35 metadata points across the App Store, Google Play, and other stores.
- Strength: pairs performance estimates with factual SDK-detection data, useful for market research and investment analysis.
- Limitation: access is sales-led, and performance figures are modeled estimates with a margin of error.
42matters API
The 42matters API focuses on app metadata, granular taxonomy, SDK detection, and publisher details, plus modeled performance metrics like downloads and monthly active users, across the App Store, Google Play, and major CTV platforms.
- Strength: strong on enrichment and SDK intelligence, available via API or bulk file dumps.
- Limitation: less focused on ASO keyword data, and refreshes less-popular apps roughly weekly rather than daily.
How do you choose the right app store API provider?
Native APIs, like Apple’s App Store Connect API and the Google Play Developer API, are built to manage and report on apps you own. Third-party tools, like AppTweak, Sensor Tower, and Appfigures, are built for market-wide intelligence: keywords, rankings, reviews, and download or revenue estimates across any app, in any category or country. The table below maps the most common goals to the right type of API.
| A use-case decision guide for choosing the right app store API provider | ||
|---|---|---|
| Your goal | Best API type | Why |
| Make programmatic changes to your app (update descriptions, screenshots, in-app events, pricing) | Native API (App Store Connect / Google Play Developer) | Write access to your store listing only exists in the official APIs. No third-party tool can push changes to the stores on your behalf. Descriptions, screenshots, pricing, and in-app events can all be updated programmatically. |
| Access only your own app’s private data (sales, proceeds, conversion rate, impressions) | Native API (App Store Connect / Google Play Developer) or Third-party API (e.g. AppTweak) with a console integration | Native APIs offer every metric at the freshest cadence, but split data across multiple report systems, formats, and retention limits. Third party APIs serve the same core metrics as JSON from one single API for both stores, with daily granularity and all-time history, at the cost of fewer metrics, refreshed less often. |
| Build an ASO dashboard (keywords, rankings, reviews in one view) | Third-party API (e.g. AppTweak) | A single cross-platform API returns iOS and Google Play keyword rankings, metadata, and review data for any app—yours or a competitor’s—without stitching together two native APIs. |
| Automate app store keyword tracking | Third-party API (e.g. AppTweak) | Native APIs don’t expose keyword rankings or search volumes for the wider market. A third-party ASO API lets you pull keyword positions and popularity scores on a schedule, across countries. |
| Integrate app store data into a BI or analytics dashboard (Looker Studio, Power BI, Tableau, BigQuery, Snowflake) | Third-party API (e.g. AppTweak) | A RESTful JSON API feeds structured market data straight into your warehouse or BI tool, so app store metrics sit alongside the rest of your business data. |
| Track and benchmark app store competitors | Third-party API (e.g. AppTweak) | Only third-party tools estimate downloads, revenue, rankings, and keyword visibility for apps you don’t own—the foundation of any competitive analysis. |
| Monitor app reviews and run sentiment analysis at scale | Third-party API (e.g. AppTweak) | Native review APIs are limited to your own apps and short time windows. A third-party reviews API pulls reviews and ratings across apps and markets for ongoing monitoring. |
| Size an app market or benchmark a whole app category | Third-party API (e.g. AppTweak) | Category-level download and revenue estimates across countries come only from third-party market intelligence providers, not native APIs. |
| Integrate your LLM with an app store API | Third-party API (e.g. AppTweak) | Neither Apple nor Google offers an LLM-ready interface to their APIs. But a third-party like AppTweak’s MCP server connects directly to your LLM environment, letting you query app store data conversationally and build reports on the fly — including competitor and keyword data no native API exposes. |
What are the risks and limitations of an app store API?
Every app store data API has structural constraints worth understanding before you build on one:
- Third-party estimates are modeled, not actuals. Download and revenue figures are useful for trends and benchmarking, but they aren’t your books.
- Native APIs are scoped to your own apps. No competitor data, no keyword rankings for the wider market.
- Private performance metrics originate in native APIs. Conversion rate, impressions, and proceeds come from App Store Connect and Google Play directly. Third-party tools can surface this data via console integration, but the source is always Apple or Google.
- Coverage, rate limits, and cost vary by provider. Country and language coverage, call limits, and pricing models differ significantly. Verify these against your use case before committing.
Conclusion
App store data is more accessible than ever, but the right API still comes down to one question: whose data do you need? Native APIs from Apple and Google are the primary source for your own app’s private performance metrics, though some third-party tools like AppTweak can surface that data too via console integration.
For everything that involves the wider market such as keywords, rankings, reviews, competitor benchmarks, and category trends, a third-party API like AppTweak’s API is the tool for the job. And as more teams wire app store data into LLMs and AI agents, a clean REST API with native model access is quickly becoming part of the baseline.
Frequently asked questions
What is an app store API?
An app store API is a programmatic interface that lets developers and data teams retrieve app store data without manually accessing a platform’s console or interface. App store APIs fall into two categories: native APIs, such as Apple’s App Store Connect API and the Google Play Developer API, which provide first-party data for apps you own and operate; and third-party APIs, such as AppTweak API, which provide market-wide intelligence keyword rankings, download and revenue estimates, reviews, and competitor data, across any app, in any country or category.
What are app store API tools used for?
App store API tools are used to integrate app store data into dashboards, BI tools, automated workflows, and AI pipelines without manual exports. Common use cases include tracking keyword rankings on a schedule, monitoring competitors, pulling review feeds for sentiment analysis, estimating market size by category, and feeding app store data into tools like Looker Studio, BigQuery, or Snowflake. Teams also use third-party APIs like AppTweak’s API to build custom ASO dashboards, power LLM and AI agent workflows, and automate recurring performance reports across the App Store and Google Play.
Is app store data public or private?
App store data is split between public and private. Public data such as metadata like app names, descriptions, screenshots, and ratings, is visible to any user in the App Store or Google Play. Estimated data. Download figures, revenue estimates, keyword rankings are modeled by third-party providers like AppTweak from observable signals, not official figures. Private data like your own app’s conversion rate, impressions, proceeds, and install sources is only accessible through either the App Store Connect API or the Google Play Developer API, and is scoped to apps you own. No third-party tool can access your private account data directly, though some, including AppTweak, can surface it by connecting your console.
Should I use Apple and Google's official APIs or a third-party API?
For most teams, the answer is both as they serve different purposes and are not interchangeable. Apple’s App Store Connect API and the Google Play Developer API are the only sources for private, first-party performance data: conversion rates, impressions, proceeds, and install sources for apps you own. No third-party tool can supply this data directly. But native APIs have no visibility into the wider market, meaning they expose no keyword rankings, competitor data, or category estimates. A third-party API like AppTweak API covers that gap, providing keyword positions, download and revenue estimates, reviews, and competitive benchmarks across any app. AppTweak API also lets you connect your App Store Connect and Google Play consoles, so your own app’s first-party data and market-wide intelligence are accessible through a single integration.
Can app store APIs be used for app keyword tracking?
Yes, but only through a third-party API. Native APIs from Apple and Google do not expose keyword ranking data for the wider market. A third-party ASO API like AppTweak API lets you pull daily keyword positions, search volume, keyword difficulty, and estimated installs per keyword for any app across multiple countries on an automated schedule. Keyword rankings endpoints cover both the App Store and Google Play, and support up to 10 keywords per queryThis makes it suitable for automated keyword tracking dashboards, competitive keyword analysis, and scheduled ASO reporting.
Can I fetch app download and revenue data via API?
Yes, but the figures are modeled estimates, not actuals. Third-party APIs like AppTweak’s provide daily download and revenue estimates for any app on the App Store or Google Play, across 100+ countries, with historical data going back to 2014. These estimates are derived from observable signals and are well-suited for benchmarking, trend analysis, market sizing, and automated reporting, though they are modeled figures. For your own app’s actual download and proceeds figures, the authoritative source is Apple’s App Store Connect API and the Google Play Developer API, which return first-party data scoped to apps you own. AppTweak API can also surface this data by connecting your App Store Connect and Google Play consoles directly.
Can I get app store ranking data via API?
Yes, category and keyword ranking data are both accessible via third-party APIs. AppTweak API includes dedicated endpoints for category rankings and keyword rankings across the App Store and Google Play. Category rankings return an app’s daily position in its top free, top paid, or top grossing chart for any supported country. Keyword rankings return the position of up to five apps for a given set of keywords, along with estimated installs per keyword. Native APIs from Apple and Google do not expose this ranking data for the wider market, meaning category and keyword visibility data is only available through third-party providers.
Can I fetch app store reviews via API?
Yes, and third-party APIs offer broader access than native ones. Apple’s and Google’s native APIs let you retrieve reviews only for apps you own, and often within limited time windows. A third-party API like AppTweak’s lets you pull full review datasets for any app — yours or a competitor’s — filtered by date, rating, keyword, or reply status, across any supported country. This makes it practical to run sentiment analysis at scale, monitor competitor feedback, or feed reviews into LLM pipelines for bug detection and feature request extraction. AppTweak’s reviews endpoint covers both the App Store and Google Play.
What is the best app store API provider to build an ASO dashboard?
For building an ASO dashboard, AppTweak API is the strongest option. Its REST API covers the full data stack an ASO dashboard requires: keyword rankings, search volume and difficulty, download and revenue estimates, category rankings, app metadata, reviews, and Apple Ads intelligence across the App Store and Google Play in 100+ countries. AppTweak API returns JSON, integrates with BI tools like Looker Studio, Power BI, Tableau, BigQuery, and Snowflake, and supports automated daily data pulls. It also offers an MCP server for teams building AI-powered workflows. AppTweak API is the only tool in this group purpose-built for ASO, with historical data going back to 2014, rather than adapted from a broader market intelligence or enrichment product.
