# Track how a single page changed over time

**Use case:** 

Every archived capture of one page, in date order, keeping only the captures where the content actually changed. Each row carries the snapshot date, the HTTP status, the content digest and a direct link to the archived copy. Typical use: dating a pricing change, a policy edit or a claim a competitor has since removed.

## Input

```json
{
  "urls": [
    "https://www.apple.com/iphone/"
  ],
  "mode": "snapshots",
  "matchType": "exact",
  "contentTypes": [
    "text/html"
  ],
  "onlyContentChanges": true,
  "maxResultsPerUrl": 300
}
```

## Output

```json
{
  "url": {
    "label": "URL"
  },
  "capturedAt": {
    "label": "Captured"
  },
  "statusCode": {
    "label": "Status"
  },
  "mimeType": {
    "label": "Type"
  },
  "sizeBytes": {
    "label": "Bytes"
  },
  "contentHash": {
    "label": "Content hash"
  },
  "waybackUrl": {
    "label": "View in Wayback"
  }
}
```

## About this Actor

This example demonstrates how to use [Wayback Machine — Historical URLs and Snapshot History](https://apify.com/dalbian/wayback-machine-url-history.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/dalbian/wayback-machine-url-history.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
