## What it does

The skill points your agent at `https://appstore.fetcher.sh`, an alternative to the official App Store API. Nine GET endpoints cover keyword search, full app and bundle records, reviews sorted by recency or helpfulness, similar apps, and a developer's catalog. Storefronts are selectable — `us`, `jp`, `de` and others. No Apple Developer Program membership is involved.

Payment comes in two flavours. Prepaid credits: grab a `bby_live_...` key and send it as `Authorization: Bearer $FETCHER_API_KEY`. Or pay per call in USDC over x402 — skip the header, and an unpaid request answers `402` with machine-readable payment terms; `@x402/fetch` signs and retries for you. Each call costs $0.003.

There is an MCP route too, at `https://appstore.fetcher.sh/mcp`, using the same Bearer key in the headers. Free tools are `search_endpoints`, `describe_endpoint` and `check_balance`; paid ones are `fetch_data`, `topup_credits` and the `appstore_apps` shortcut. No rate limits apply, and upstream failures are not refunded because settlement happens before delivery. Get the key first — without it, x402 is your only option.

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/fetcher-sh/fetcher-skills/tree/HEAD/skills/app-store/SKILL.md

## When to use it
- find iOS apps by keyword in a specific country storefront
- pull an app's reviews sorted by helpfulness
- list apps similar to a given one
- browse a developer's full app catalog
- compare search results across country storefronts

## Example prompts

- Pull reviews for app `324684580` sorted by helpfulness
- Show the app catalog for developer `284882218`

  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.

# 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](../fetcher/SKILL.md):

```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)

| 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`).

## Scenarios
