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:

bash
# 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)

EndpointWhat it returns
/api/appsApps matching a keyword; page and country storefront filters
/api/apps/{appId}An app's full details
/api/apps/{appId}/reviewsAn app's reviews
/api/apps/{appId}/similarApps similar to a given app
/api/bundlesApp bundles matching a keyword
/api/bundles/{bundleId}A bundle's full details
/api/bundles/{bundleId}/reviewsA bundle's reviews
/api/bundles/{bundleId}/similarBundles 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).

Scenarios

US storefront search:

bash
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "term=habit tracker" -G \
  --data-urlencode "country=us" \
  "https://appstore.fetcher.sh/api/apps"

Japanese storefront search:

bash
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "term=camera" -G \
  --data-urlencode "country=jp" \
  "https://appstore.fetcher.sh/api/apps"

An app's full details, then reviews sorted by helpfulness:

bash
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "country=us" -G \
  "https://appstore.fetcher.sh/api/apps/324684580"

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "country=us" -G \
  --data-urlencode "sort=helpful" \
  "https://appstore.fetcher.sh/api/apps/324684580/reviews"

Apps similar to a given app:

bash
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "country=us" -G \
  "https://appstore.fetcher.sh/api/apps/324684580/similar"

Search and fetch app bundles:

bash
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "term=photo editing suite" -G \
  "https://appstore.fetcher.sh/api/bundles"

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "country=us" -G \
  "https://appstore.fetcher.sh/api/bundles/1234567890"

A developer's full app catalog:

bash
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://appstore.fetcher.sh/api/developers/284882218"

MCP

json
{
  "mcpServers": {
    "app-store": {
      "url": "https://appstore.fetcher.sh/mcp",
      "headers": { "Authorization": "Bearer bby_live_..." }
    }
  }
}

Free: search_endpoints, describe_endpoint, check_balance. Paid: fetch_data (any endpoint above), topup_credits, plus the named shortcut appstore_apps. Drop the headers block to pay per call with x402 instead — see the `fetcher` skill for the full flow.

Errors

  • 400 — missing/invalid parameter (message names it)
  • 401 — unknown or rotated key
  • 402 — payment required (x402 challenge) or topup_required (credits

exhausted)

  • 404 — not a priced path
  • No rate limits; no refunds on upstream failures (settlement precedes

delivery)
