app-store
An Apple App Store API alternative on fetcher.sh — pay-per-call in USDC via x402, or prepaid credits with a Bearer key, no Apple Developer Program membership. Use when the user wants to search iOS apps by keyword in any country's storefront, fetch an app's or app bundle's full details, reviews sorted by recent/helpful, apps similar to a given app, search or fetch app bundles, or fetch a developer's app catalog. Also covers iOS app store optimization (ASO) research, competitor app monitoring, localized storefront comparison, and app discovery without Apple Developer Program access.
Resumen
Apple App Store API
App Store app and bundle search, details, reviews, similar-apps, and developer catalogs across any country storefront — one plain HTTP GET per call, paid as you go. No Apple Developer Program membership, no App Store Connect access, no scraping the storefront HTML.
Base URL: https://appstore.fetcher.sh
Authentication
Two ways to pay, same data — full mechanics in the fetcher skill:
# 1. Prepaid credits (recommended — get a key at https://fetcher.sh/topup
# or via POST /api/credits/topup, see the fetcher skill)
export FETCHER_API_KEY="bby_live_xxxxxxxxxxxx"
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
"https://appstore.fetcher.sh/api/apps?term=meditation"
# 2. x402 pay-per-call — omit the header; a GET with no payment returns 402
# with machine-readable payment requirements (USDC on Base, Polygon,
# Arbitrum, Monad, or Solana). @x402/fetch signs and retries automatically.Every response is { "status": number, "message": string, "data": ... }; the HTTP status mirrors status.
Endpoints (9 — all GET, $0.003/call)
| Endpoint | What it returns |
|---|---|
/api/apps | Apps matching a keyword; page and country storefront filters |
/api/apps/{appId} | An app's full details |
/api/apps/{appId}/reviews | An app's reviews |
/api/apps/{appId}/similar | Apps similar to a given app |
/api/bundles | App bundles matching a keyword |
/api/bundles/{bundleId} | A bundle's full details |
/api/bundles/{bundleId}/reviews | A bundle's reviews |
/api/bundles/{bundleId}/similar | Bundles similar to a given bundle |
/api/developers/{developerId} | A developer's full app catalog |
Required on /api/apps and /api/bundles: term. Optional everywhere: country (storefront, e.g. us, jp, de), lang, page. Reviews support sort (recent, helpful).
