They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows. 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/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.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/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 ## Dataroma Superinvestor Scraper Apify actor that scrapes superinvestor 13F portfolio data from [dataroma.com](https://www.dataroma.com) — no browser, plain HTTP + HTML parsing. ### Modes | Mode | What you get | Dataset items | |---|---|---| | `holdings` | Portfolios for specific manager codes | One item **per holding** | | `managers` | List of all ~80 tracked managers | One item per manager (code, name, URL) | | `all_holdings` | Every manager's full portfolio | One item per holding, all managers | ### Example input ```json { "mode": "holdings", "managerCodes": ["BRK", "psc"], "requestDelaySecs": 1 } ```` Manager codes are Dataroma's short codes (`BRK` = Berkshire Hathaway / Warren Buffett). Full `holdings.php?m=XXX` URLs are also accepted. Run the actor once in `managers` mode to discover all valid codes. ### Output (holdings item) ```json { "manager_code": "BRK", "manager": "Warren Buffett - Berkshire Hathaway", "ticker": "AAPL", "company": "Apple Inc.", "portfolio_pct": 21.99, "activity": "", "shares": 227917808, "reported_price": 253.79, "value": "$57,843,261,000", "value_usd": 57843261000.0, "recent_price": 330.84, "change_pct": 30.36, "period": "Q1 2026", "fetched_at": "2026-07-17T12:00:00Z" } ``` A run summary (item counts + any per-manager errors) is stored in the key-value store under the key `SUMMARY`. # Actor input Schema ## `mode` (type: `string`): What to scrape. `holdings` = portfolios for the manager codes below. `managers` = the list of all tracked managers. `all_holdings` = every manager's full portfolio (~80 pages, slower). ## `managerCodes` (type: `array`): Dataroma manager codes (e.g. `BRK` = Berkshire Hathaway / Warren Buffett). Full dataroma.com holdings URLs also work. Used only in `holdings` mode. Run `managers` mode first if you don't know the codes. ## `maxManagers` (type: `integer`): Safety cap on how many managers to fetch in `all_holdings` mode. 0 = no limit. ## `requestDelaySecs` (type: `integer`): Polite throttle between page fetches. Keep at 1+ to avoid getting blocked. ## `proxyConfiguration` (type: `object`): Proxy to route requests through. Dataroma is lenient, so this is usually unnecessary, but enable Apify Proxy if you hit blocks. ## Actor input object example ```json { "mode": "holdings", "managerCodes": [ "BRK" ], "maxManagers": 0, "requestDelaySecs": 1, "proxyConfiguration": { "useApifyProxy": false } } ``` # 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 = { "managerCodes": [ "BRK" ] }; // Run the Actor and wait for it to finish const run = await client.actor("moving_beacon-owner1/dataroma-superinvestor-scraper").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 📖?
