AdGuard VPN: API Tester

Test any HTTP API from your iPhone or iPad. Build a request, tap Send and read the answer in seconds: status, headers, timing and a readable JSON body.

AdGuard VPN: API Tester is a complete HTTP client for developers, QA engineers and anyone who works with web APIs.

BUILD REQUESTS
• GET, POST, PUT, PATCH, DELETE, HEAD and OPTIONS
• Query parameters and headers you can switch on and off
• JSON, text, XML and form bodies
• Bearer token, Basic and API key authorization
• Import a request from a cURL command

READ EVERY RESPONSE
• Status code with its meaning, response time and size
• Pretty JSON, a collapsible tree, raw text and preview
• Search inside the body, copy or share any part
• Response headers and a timing breakdown

AI ASSISTANT
• Describe a request in plain words and get it ready to send
• Ask the assistant to explain a response or an error code
• Get suggested tests for the response you are looking at
The assistant asks for your consent first. Authorization headers, cookies, tokens and passwords are masked on your device before anything is sent. AI answers can be wrong, so check them before you rely on them.

ORGANIZE YOUR WORK
• Collections with folders, plus a history of everything you sent
• Environments with {{variables}} for dev, staging and production
• Run a whole collection and see which requests pass their tests
• Response tests for status, time, headers and JSON values
• Export code snippets for cURL, Swift, Python and JavaScript
• Import and export Postman Collection v2.1 files

PROTECTED CREDENTIALS
Keep tokens, passwords and API keys in a vault stored in the iOS Keychain and unlocked with Face ID or your passcode. Requests use them without showing them on screen.

LOCAL NETWORK
Send requests to servers on your Wi‑Fi, such as a laptop, a router or a smart home device, and find HTTP services nearby with Bonjour. The app asks for Local Network permission only for this.

PRIVATE BY DESIGN
No account, no ads and no tracking. Your requests, collections and credentials stay on your device.

A tool for developers: the app does not provide a VPN connection and does not route, capture or inspect the traffic of other apps.
