How this service works
App Store listing data for any app on any storefront: current and all-time star ratings with review counts, version, release notes, size, price, content rating, genres and release dates. Includes a version-sentiment read comparing the current version's rating against its all-time average, which is how you spot a release that damaged an app. Look up by numeric App Store id or search by name.
Output
Returns structured App Store data including current star rating, all-time star rating, review count, app version, release notes, file size, price, content rating, genre tags, and release dates. Also includes a version-sentiment indicator comparing the current version's rating to the all-time average so you can tell whether a recent update helped or hurt the app's reputation.
Example use cases
Spot a damaging app update
“Check the App Store listing for Instagram — I want to know if the current version's rating is significantly lower than its all-time average, which would tell me a recent release upset users.”
Competitive app research
“Search the US App Store for 'Calm' and give me its current price, genres, content rating, and how many reviews it has.”
App version release notes lookup
“Pull up the App Store page for app ID 284882215 and show me the latest version number and its release notes.”

Endpoint
GEThttps://x402-filings.datalayer.workers.dev/v1/apps/lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need rich App Store metadata beyond what a simple search returns — especially when you want the version-sentiment delta to detect whether a recent release damaged an app's reputation. Prefer this over scraping the App Store or using iTunes Search API directly when you need structured, normalized output with the current-vs-all-time rating comparison built in. Ideal for competitive intelligence, app monitoring, and release quality assessment workflows.
Side effects
- App ID not found: returns empty or error if numeric ID doesn't match any app
- Search returns no results: if the app name search yields nothing, the result set will be empty
- Country code invalid: unrecognized storefront code may default to US or return an error
- Limit out of range: limit values outside 1-25 may be rejected or clamped
- Rate limiting or payment failure: x402 payment not processed results in 402 response
