ASO SkillWhy it exists
ASO work often starts with a simple question: what currently appears for this keyword, how competitive does the result set look, and how much demand does the keyword have? Answering that question should not require operating a large dashboard or reverse-engineering an undocumented response. ASO Skill provides a compact, typed HTTP API for current App Store search results, keyword difficulty, popularity, and app metadata.
The service is intentionally narrow. It favors predictable JSON, explicit cache and observation times, a public OpenAPI contract, and credit behavior that automated clients can understand. Successful data calls cost one credit; invalid requests and failed upstream calls do not. API keys are long-lived until revoked or their optional expiry and are managed separately from short-lived website sessions.
Who operates it
ASO Skill is operated by Hesselbom Tech AB, a Swedish company with organization number 559450-0372. Product development, infrastructure, support, and privacy requests are handled by the same small team. The service runs in AWS's Stockholm region, while the public website is deployed separately through Vercel.
ASO Skill is independent of and is not affiliated with, endorsed by, sponsored by, or operated by Apple Inc.
