API Client - REST HTTP Tester

REST API Tester & HTTP Client

Free · Designed for iPad. Not verified for macOS.

Test any API right from your phone. Paste a URL, hit send, see the response. API Client is a lightweight REST and HTTP tester. No account needed. No cloud sync. No setup. Just open the app and start testing. ▸ JUST PASTE & SEND Enter any URL, pick a method (GET, POST, PUT, PATCH, DELETE), and tap Send. See status codes, response time, headers, and formatted JSON — all in one view. ▸ SMART JSON VIEWER Collapsible JSON tree with search, tap-to-copy, and syntax highlighting. Format or minify JSON with one tap. Build request bodies visually without typing raw JSON. ▸ ENVIRONMENTS Switch between development, staging, and production with one tap. Each environment stores its own base URL, bearer token, API key, and custom headers. Use {{variables}} across all requests. ▸ COLLECTIONS & HISTORY Save requests to collections. Pin favorites for quick access. Full history grouped by date with one-tap rerun. Search across all saved requests. ▸ cURL IMPORT & EXPORT Paste any cURL command to import instantly. Export any request as cURL to share with your team or use in terminal scripts. ▸ API MONITORING Set up automatic health checks for your endpoints. Get push notifications when an API goes down or degrades. Track incidents and recovery times. ▸ TEST SUITES & ASSERTIONS Group requests into test suites. Add response assertions — validate status codes, check JSON fields, verify headers. Run all tests with one tap. ▸ API DOCS GENERATOR Generate shareable PDF documentation for any endpoint — method, URL, headers, body, response samples, and status codes included. WORKS GREAT FOR • Developers testing REST APIs from anywhere • Students learning HTTP methods and API concepts • QA engineers validating endpoints • DevOps checking microservice health • Anyone who needs an API client on mobile WHY API CLIENT? This app runs entirely on your device. Your API keys and tokens stay on your phone. No sign-up required — just open and test.
