About this tool

What is the API Explorer?

The API Explorer is a browser-based tool for sending HTTP requests and inspecting responses in real time. It lets you test REST API endpoints directly — without installing Postman, writing curl commands, or switching between apps. Enter a URL, choose a method, add headers or a body, and send.

It's designed for developers who want a fast, frictionless way to test an endpoint during development, verify an API integration, or debug a request that isn't behaving as expected.


How to Use the API Explorer

  1. Enter the endpoint URL — paste the full API URL you want to test, including any path parameters.
  2. Select the HTTP method — choose GET, POST, PUT, PATCH, DELETE, or HEAD depending on what the endpoint expects.
  3. Add request headers — include headers like Authorization, Content-Type, or any custom headers required by the API.
  4. Add a request body — for POST and PUT requests, enter your JSON payload in the body field.
  5. Send the request — the tool fires the request from your browser and displays the full response: status code, response headers, and body.

What You Can Do With It

Test public APIs — Explore open APIs (weather, maps, data sources) without writing a single line of code.

Debug authentication issues — Test Bearer tokens, API keys, and Basic Auth headers to confirm your credentials are being sent correctly.

Verify request formatting — Check that your JSON body structure matches what the API expects before writing it into your application.

Inspect response structure — See exactly what fields an API returns so you can map them correctly in your code.

Test different environments — Switch between development, staging, and production endpoints quickly by changing the URL.


Supported Request Types

The API Explorer supports all standard HTTP methods used in REST APIs:

  • GET — retrieve data from an endpoint
  • POST — send data to create a resource
  • PUT / PATCH — update an existing resource
  • DELETE — remove a resource
  • HEAD — retrieve headers only, without a response body

Custom headers and JSON request bodies are supported for all applicable methods.


Privacy

API requests are sent directly from your browser to the target endpoint. No request data, response data, URLs, headers, or authentication tokens are stored or logged on our servers. Your API keys and credentials never leave your device.
