## What's an Apify Actor?

Actors are web data automations that power AI and operations. 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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

Collector Car Auction Outcome Monitor turns public auction result pages into analysis-ready records. No marketplace login is required for supported pages.

### 🔍 What does this Actor do?

Paste public result pages or individual listings from Bring a Trailer and Hagerty Marketplace. The Actor saves each genuine outcome without filling gaps with placeholder data.

Use it to:

- Compare sold prices across two established collector-car marketplaces.
- Separate sold, reserve-not-met, withdrawn, and other ended outcomes.
- Track new listings and price or status changes between scheduled runs.
- Build comp sets with vehicle year, make, model, mileage, and auction activity.
- Keep the original listing URL and public lead image beside every record.

### 👥 Who uses it?

- **I am a collector-car dealer** comparing recent sold outcomes before pricing an acquisition or trade-in.
- **I am an appraiser** building source-linked comp sets for a valuation report.
- **I am an auction analyst** monitoring reserve performance and outcome changes across scheduled runs.
- **I am an enthusiast** tracking the closing prices of specific makes, models, or eras.

### ❓ FAQ

##### Which collector-car auctions are supported?

The first release supports public Bring a Trailer and Hagerty Marketplace outcome pages. Other marketplaces are excluded until their access and usage conditions are suitable.

##### Does it get blocked?

The supported pages were selected because their public auction content is available without a login. Optional network routing can help with ordinary regional connection issues.

##### How fresh are the auction results?

Each run reads the public page at run time. Schedule repeat runs when you need a regular sold-comp or outcome-change feed.

##### How does change detection work?

The Actor stores each listing's last observed status and price. Later runs mark new records and genuine changes without inventing missing history.

# Actor input Schema

## `startUrls` (type: `array`):

Public Bring a Trailer result or listing URLs and Hagerty Marketplace result or auction URLs.

## `keyword` (type: `string`):

Keep records whose vehicle title, make, model, or description contains this text. Leave blank for every vehicle.

## `outcomeStatuses` (type: `array`):

Save sold, reserve-not-met, withdrawn, or other ended auction outcomes.

## `onlyChanges` (type: `boolean`):

Compare with the prior run in the same storage and save only new listings or changed status and price records.

## `includeDescription` (type: `boolean`):

Include the public vehicle description or result-card excerpt when available.

## `includeImages` (type: `boolean`):

Include the public lead vehicle image URL when available.

## `maxItems` (type: `integer`):

Maximum number of outcome records saved in one run.

## `maxConcurrency` (type: `integer`):

Number of public pages read in parallel. Keep this low to respect source load.

## `proxyConfiguration` (type: `object`):

Optional proxy settings. The default uses Apify datacenter proxy routing in cloud runs.

# 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 = {
    "startUrls": [
        {
            "url": "https://bringatrailer.com/auctions/results/?result=sold"
        },
        {
            "url": "https://www.hagerty.com/marketplace/search?sortBy=ending_soonest&type=auctions&forSale=false"
        }
    ],
    "keyword": "",
    "outcomeStatuses": [
        "sold",
        "reserve_not_met",
        "withdrawn",
        "ended"
    ],
    "onlyChanges": false,
    "includeDescription": true,
    "includeImages": true,
    "maxItems": 10,
    "maxConcurrency": 2,
    "proxyConfiguration": {
        "useApifyProxy": true
    }
};

// Run the Actor and wait for it to finish
const run = await client.actor("getascraper/collector-car-auction-outcome-monitor").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);
});

## Python example

```python

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input

# Run the Actor and wait for it to finish

# 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}")

apify call getascraper/collector-car-auction-outcome-monitor --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,getascraper/collector-car-auction-outcome-monitor"
        }
    }
}

```

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).
