Usage

Local Run

$apify run --input-file dev-inputs/example.json

Cloud Run

$apify call technicaldost/shopify-price-delta-monitor --input-file dev-inputs/example.json

How It Works

1. First Run: Fetches all products, builds price snapshot and saves it to a named key-value store in your account (shopify-price-delta-<shop-domain>), so it is kept between runs. No changes output (nothing to compare).
2. Subsequent Runs: Fetches products, compares with stored snapshot, outputs only changed prices, updates snapshot.

Use Cases

• Price drop alerts for competitor monitoring
• Sale detection for arbitrage
• Price history tracking for e-commerce analytics
• Flash sale monitoring

How to use Shopify Price Monitor

1. Open Shopify Price Monitor on Apify Store and click Try for free.
2. Fill in the input (the form is prefilled with a working example) and click Start.
3. Watch results appear in the Output tab, then download them as JSON, CSV, Excel or HTML, or read them through the API.
4. Optional: save the input as a task and add a schedule to run it automatically, or connect it to your tools with integrations and webhooks.

Use Shopify Price Monitor with AI agents (MCP)

Give Claude, ChatGPT, Cursor, VS Code or any MCP client this Actor as a tool through the hosted Apify MCP server. The agent sees the input fields with descriptions and example values, runs the Actor, and reads the results.

MCP server URL (this Actor only):

https://mcp.apify.com/?tools=technicaldost/shopify-price-delta-monitor

Claude Code:

$claude mcp add --transport http apify "https://mcp.apify.com/?tools=technicaldost/shopify-price-delta-monitor" --header "Authorization: Bearer YOUR_APIFY_TOKEN"

Cursor, VS Code, Claude Desktop and other clients (mcp.json or the client's MCP settings):

{
  "mcpServers": {
    "apify": {
      "url": "https://mcp.apify.com/?tools=technicaldost/shopify-price-delta-monitor",
      "headers": { "Authorization": "Bearer YOUR_APIFY_TOKEN" }
    }
  }
}

Clients that support sign-in (such as Claude.ai connectors) can use the URL without a token and log in to Apify instead. Get your token in Apify Console → Settings → API & Integrations, or generate a ready config for your client at mcp.apify.com. In the agent the tool is named technicaldost--shopify-price-delta-monitor; ask it, for example, to "run Shopify Price Monitor with {"shopDomain": "kyliecosmetics.com"}".

AI agents without an Apify account can also run and pay for this Actor per request with x402 agentic payments.

Run Shopify Price Monitor via API

Run the Actor and get its results in one call (replace YOUR_APIFY_TOKEN):

curl -X POST "https://api.apify.com/v2/acts/technicaldost~shopify-price-delta-monitor/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"shopDomain": "kyliecosmetics.com"}'

Python (pip install apify-client):

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("technicaldost/shopify-price-delta-monitor").call(run_input={"shopDomain": "kyliecosmetics.com"})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript / TypeScript (npm install apify-client):

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_APIFY_TOKEN' });
const run = await client.actor('technicaldost/shopify-price-delta-monitor').call({"shopDomain": "kyliecosmetics.com"});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

Long runs: start them with POST /v2/acts/technicaldost~shopify-price-delta-monitor/runs and fetch the dataset when the run finishes, or receive a webhook.

Integrations
