## 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

## Knasta Chile Scraper - price comparison, offers, and retailers

Search public [Knasta.cl](https://knasta.cl/) result pages and export normalized Chilean product prices to an Apify dataset. This Actor is designed for price monitoring, competitor research, offer tracking, ecommerce analytics, and retail intelligence in Chile.

### What this Actor extracts

Each dataset row represents one product shown by Knasta:

- Product name, brand, category, and stable Knasta product key.
- Current, internet, card, and previous prices in CLP when available.
- Discount percentage, price change, offer flag, and best-price flag.
- Retailer, rating, image, and the original retailer product URL.
- Search page, result position, and UTC extraction timestamp.

### Input example

```json
{
  "query": "iphone",
  "maxItems": 50,
  "maxPages": 2,
  "failOnNoResults": false
}
```

Use a specific brand, model, or product family for the most relevant comparison. Runs are intentionally bounded to at most 200 products and five pages.

### Output example

```json
{
  "title": "iPhone 16e Blanco",
  "brand": "Apple",
  "retailer": "Falabella",
  "currency": "CLP",
  "current_price": 519990,
  "previous_price": 529990,
  "discount_percentage": 1.89,
  "is_best_price": true,
  "product_url": "https://www.falabella.com/..."
}
```

`OUTPUT` contains a compact run summary. Product rows are stored in the default dataset and can be downloaded as JSON, CSV, Excel, or through the Apify API.

### Responsible source use

The Actor reads only Knasta's public `/results` HTML pages and their embedded Next.js data. Knasta's current `robots.txt` disallows `/api` and `/redirect`; this Actor never calls those paths, does not log in, does not bypass access controls, and uses a low fixed request rate. Retail prices remain subject to confirmation on the linked retailer website.

### No-result and source errors

- An empty valid search finishes with `status: no_results` unless `failOnNoResults` is enabled.
- Invalid input fails before any request is made.
- Blocking, rate limits, malformed public data, and persistent network errors fail clearly instead of returning invented or stale products.

### Pricing

This Actor uses Pay per event at **USD 0.003 per product result** saved to the dataset. There is no Actor-start fee. The user also pays Apify platform usage.

# 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 '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "query": "iphone",
    "maxItems": 50
};

// Run the Actor and wait for it to finish
const run = await client.actor("scraperschile/knasta").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);
});

client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {
    "query": "iphone",
    "maxItems": 50,
}

# Run the Actor and wait for it to finish
run = client.actor("scraperschile/knasta").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():

## CLI example

```bash
echo '{
  "query": "iphone",
  "maxItems": 50
}' |
apify call scraperschile/knasta --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,scraperschile/knasta"
        }
    }
}
```

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).
