Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## 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. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## SaaS Pricing Page Change Monitor Monitor SaaS pricing pages and detect changes to plans, prices, trials, billing terms, and feature packaging. ### What it does - Checks SaaS pricing pages and related internal pricing links - Uses static HTTP first, then falls back to Playwright for blocked or JavaScript-heavy pricing pages - Extracts plan names, price text, billing language, trial wording, and feature highlights - Stores a structured snapshot for each checked page - Compares the latest page snapshot with the previous stored snapshot - Flags whether pricing-related content changed since the last run ### Good uses - watch competitor pricing changes - track plan and packaging changes over time - monitor free trial language and billing terms - collect structured pricing page data for research ### Output fields Each dataset item includes fields like: - `url` - `pageTitle` - `sourceType` - `loadMethod` - `fallbackReason` - `plans` - `priceMentions` - `billingTerms` - `trialTerms` - `featureHighlights` - `usageLimitMentions` - `changeDetected` - `changeSummary` ### Default input The default setup checks: - `https://www.notion.so/pricing` - `https://zapier.com/pricing` So a default run should produce useful rows without extra setup. Internal pricing-link discovery is available, but it is off by default so the first run stays focused on the exact pricing pages you provide. Browser fallback is on by default. This helps recover useful rows from pages that block plain HTTP requests or render pricing cards only in the browser. # Actor input Schema ## `urls` (type: `array`): SaaS pricing page URLs to check. ## `followInternalPricingLinks` (type: `boolean`): Follow internal links that look like pricing, plans, billing, or compare pages. ## `captureSnapshot` (type: `boolean`): Store an extracted page snapshot record for each checked page. ## `compareWithPreviousRun` (type: `boolean`): Compare extracted pricing data with the latest stored snapshot for the same page. ## `useBrowserFallback` (type: `boolean`): Use a Playwright browser fallback when a pricing page is blocked, JavaScript-heavy, or returns weak static results. ## `maxPagesPerDomain` (type: `integer`): Maximum number of pricing-related pages to check per domain. ## `requestTimeoutSecs` (type: `integer`): Maximum time to wait for each page request. Some sites may still block plain HTTP requests and return an error row. ## `browserNavigationTimeoutSecs` (type: `integer`): Maximum time to wait for a Playwright browser page load when fallback is used. ## `browserSettleMillis` (type: `integer`): Extra wait after page load to let pricing components render before extraction. ## Actor input object example ```json { "urls": [ "https://www.notion.so/pricing", "https://zapier.com/pricing" ], "followInternalPricingLinks": false, "captureSnapshot": true, "compareWithPreviousRun": true, "useBrowserFallback": true, "maxPagesPerDomain": 3, "requestTimeoutSecs": 30, "browserNavigationTimeoutSecs": 45, "browserSettleMillis": 1500 } ```` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "urls": [ "https://www.notion.so/pricing", "https://zapier.com/pricing" ] }; // Run the Actor and wait for it to finish const run = await client.actor("happyfhantum/saas-pricing-page-change-monitor").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
