API Inspector — JSON, Network Requests & Media Viewer

See every API request a website makes. View JSON/XML/CSV/HTML responses, copy as cURL, replay HTTP requests and save as a HAR File.

API Inspector watches the website you're currently using and shows the API calls and media resources it loads. Inspect network requests, view responses in the appropriate format, replay requests with custom headers or body, copy requests as cURL, play detected media, and export captured activity as a HAR file — all from one convenient developer tool. No account or API key is required. 🔍 Inspect Network Requests See the network requests made by a webpage, including Fetch, XHR, and WebSocket requests. Each captured request shows useful details such as its HTTP method and status code, making it easier to understand how a website communicates with its backend. 🧩 Filter Network Traffic Quickly narrow down captured resources by type, including JSON, documents, XML, HTML, CSV, media, and other requests. This makes it easier to find a specific resource without manually searching through unrelated network activity. 📦 View Responses Open captured responses directly in the appropriate Coders Hub tool. JSON responses can be viewed as an expandable tree, while supported XML, HTML, and CSV responses can be opened in their respective viewers and formatters. 🔄 Replay HTTP Requests Send a captured HTTP request to the HTTP Request Builder and replay it with your own headers and body. This can help when debugging an API, testing a different request configuration, investigating a response, or reproducing a network request. 💻 Copy as cURL Copy a captured request as a ready-to-use cURL command, or copy its URL when you only need the endpoint. The cURL command can be used in a terminal, script, documentation, or API testing workflow. 🎬 Detect & Play Media API Inspector can identify media resources loaded by a webpage. Detected images can be opened directly in the browser. Supported video, audio, and streaming URLs can be opened in the Coders Hub Online Media Player. 💾 Export as HAR Export captured network activity as a `.har` file for later analysis. HAR files can be useful for debugging websites, investigating network requests, sharing captured traffic, or keeping a record of a browsing session. Inspect. Understand. Replay. Export.
