API Testing Tools is a fast, private HTTP client for your iPhone, set like a newspaper. Write a request, send it, and read the answer in clean type, with the timings, headers and checks that matter. THE DAILY REQUEST • A front page with today's sends, what needs your attention, your slowest endpoints and the requests you pin, ready to send in one tap. REQUESTS • Every method, query parameters, headers, and JSON, form, XML, text or GraphQL bodies. • Bearer token, Basic and API-key authentication. • {{Variables}} and environments: switch between staging and production in one tap. Built-in {{$uuid}}, {{$timestamp}}, {{$isoTimestamp}} and more. • Paste a cURL command from docs or your browser, or import a Postman collection or environment. RESPONSES • Pretty-printed JSON that keeps the server's key order, raw text with search, image and HTML previews. • Fields: every value in a JSON response with its path. Tap one to check it or save it into a variable. • Status, size and where the time went: DNS, connect, TLS, waiting and download. • Live streams: watch server-sent events arrive as they happen, with event names, ids and timings. CHECKS AND CHAINS • Checks on every response: status, response time, headers, body text and JSON paths. • Save a value from a response into a variable, like a login's token, and use it in the next request. • Run a whole collection in order and see at a glance what passed and what needs a look. AND • A history of every send with its full response, and a filter for what failed. • Copy any request as cURL, or export it as HTTPie, JavaScript, Python, Swift or Go. • Export and import your library as JSON. • Self-signed certificates for local dev servers (optional), cookies, timeouts and redirects under your control. • Light and dark editions. Free, with no ads, no tracking and no account. Requests go straight from your iPhone to the servers you call; nothing passes through anyone else. An optional "Buy me a coffee" tip supports the developer and unlocks nothing.
