# Analyze XHR and Fetch API Call Data

**Use case:** 

Gain insights into web requests by examining XHR and Fetch API calls from specified pages. This task captures essential network traffic over a short duration, presenting a concise overview of any failures or redirects that occur. With a focused capture on a single page, understand how resources are loaded and how they impact performance.

## Input

```json
{
  "startUrls": [
    {
      "url": "http://127.0.0.1/"
    }

## About this Actor

This example demonstrates how to use [Browser Network & HAR Inspector | XHR, Fetch, API Traffic](https://apify.com/produkdigitalali/browser-network-har-capture-inspector.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/produkdigitalali/browser-network-har-capture-inspector.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
