It has two run modes. 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. Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md. ## 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. 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 examples already wired to this Actor's own input schema, see the [API](#api) section below. 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`). # README ## 🐋 Fast WhaleWisdom Scraper — Hedge Fund 13F Holdings & Smart Money > ### 🎁 Free Tier: Extract up to 1,000 items 100% FREE! > > **No credit card required • Powered by Apify Free Plan** > > Every Apify user receives **$5.00 in free starter credits every month**! > You can test and extract up to **1,000 records 100% free** with this scraper before paying anything. > > [![Free Trial](https://img.shields.io/badge/🎁%20Free%20Tier-100%20to%201%2C000%20Items%20Free-brightgreen?style=for-the-badge\&logo=apify)](https://apify.com/rbbscrap/fast-whalewisdom-scraper/input) > [![Monthly Free Credits](https://img.shields.io/badge/Apify%20Free%20Plan-%245%2FMonth%20Included-blue?style=for-the-badge\&logo=cashapp)](https://apify.com/rbbscrap/fast-whalewisdom-scraper/input) > [![No Credit Card](https://img.shields.io/badge/No%20Credit%20Card-Zero%20Risk-purple?style=for-the-badge)](https://apify.com/rbbscrap/fast-whalewisdom-scraper/input) > > 👉 [**Click here to Launch a Free Test Run with 1 Click (Pre-filled)**](https://apify.com/rbbscrap/fast-whalewisdom-scraper/input) Ultra-fast, enterprise-grade scraper for **WhaleWisdom** and official SEC Form 13F institutional portfolios.

Clients without OAuth support can send an `Authorization: Bearer ` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations). ## OpenAPI specification Download the OpenAPI definition: https://api.apify.com/v2/actors/ZL0PQV12NsnfmahCq/builds/KpnRLI5IzHMsgz3bC/openapi.json
