## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. 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

## 🛍️ Shopify Sales & Revenue Delta Spy

> Competitor E-Commerce Intelligence: Track any competitor Shopify store's **daily revenue ($)**, **exact units sold**, **bestselling product rankings**, and **variant stockout velocity** using automated inventory delta math and cart quantity validation leaks — with **zero store admin access needed**.

***

### ⚡ Key Features

- **Mathematical 24-Hour Inventory Delta:** Automatically calculates daily sales by tracking inventory decrements over time:
  $$\text{Units Sold}*i = \max(0, \text{Stock}*{t-1} - \text{Stock}\_t)$$
  $$\text{Daily Store Revenue} = \sum (\text{Units Sold}\_i \times \text{Price}\_i)$$
- **Shopify Cart Availability Leak:** Exploits Shopify's native `/cart/add.js` inventory validation error responses to reveal exact remaining stock quantities even on stores that hide inventory counts from their theme.
- **Bestselling Product Rankings:** Identifies the top 20% of catalog SKUs generating 80% of competitor daily cashflow.
- **Total Catalog Retail Valuation:** Computes total on-hand inventory asset value based on active product variants and catalog pricing.
- **Fast-Depleting SKU Alerts:** Detects viral products with high sales velocity before they sell out.
- **Zero Proxies & Zero API Keys:** Operates in pure Python directly against public Shopify JSON endpoints with 100% reliability.

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
