## 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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Zillow Real-Estate Monitor — Price Drops & New Listings (Vigia)

> Monitor Zillow searches (a ZIP, a neighborhood, a saved search) and get alerted only on real changes: price cuts, brand-new listings, and homes going pending/sold — with lowest-price-ever tracking. Charges only on change.

### Free tier — 10 results free on every run

**The first 10 results of every run are free**, on every run you ever make —
not a one-off trial. Run it on your own subjects and see the real output before
you are billed for a single result.

One guard: the free allowance never covers more than half of a run, so a run
returning 6 results gets 3 free. That keeps the offer sustainable.

### What it does

Monitor a real-estate search for new and changed listings. You get **only what changed since your last check** — never a full re-dump to diff yourself.

### Why Vigia — 5 advantages a raw scraper can't match

1. **You pay the alert price only for real change.** New-listing change alerts are billed only for genuinely new listing changes since your last check. A quiet run bills just the small source-check fee (the cost of looking) — never the alert price on unchanged data. Raw scrapers bill every row of a full re-scan every run.
2. **Never billed on a failed source.** The source check is charged only when the source actually responded. If it's down, you don't pay for our outage.
3. **Append-only delta + spike signal.** The first monitored run stores a free baseline; later runs deliver only what's new, plus a velocity-spike alert when volume suddenly surges (trend / review-bomb / hiring-surge).
4. **Hard cost cap you control.** Set `maxTotalChargeUsd` and the run can never bill above it — predictable spend, no surprise invoice.
5. **Agent-ready output.** Clean, normalized rows and a `RUN_SUMMARY.json` with ready-to-use signals — chainable from any MCP / A2A agent in one step.

### Example input

```json
{
  "searchUrls": [
    "https://www.zillow.com/homes/for_sale/Austin,-TX/"
  ],
  "monitorEnabled": true,
  "maxTotalChargeUsd": 1.0
}
````

Set `monitorEnabled: true` so the first run stores a free baseline and later runs return only new results. Pin a `monitorId` to keep separate targets from sharing state.

### Output

Each row is a normalized change record: `record_id`, `name`, `price`, `previous_price`, `price_change`, `change_type`, `home_status`, `at_lowest_ever`, `source_url`. A `RUN_SUMMARY.json` accompanies every run with the aggregated signal (counts, velocity spikes, trend).

### How you're charged

- **Listing change alert** — billed once per new listing change since the last check (this is the only charge that scales with change).
- **Source check** ($0.20) — billed once per monitored target per run, **only when the source responded**. A failed source is free.
- **A quiet run bills only the source check** ($0.20), never the alert price. Vigia never scrapes the source itself; it chains a licensed scraper, caps every call, and passes you only the delta.

# Actor input Schema

## `searchUrls` (type: `array`):

Zillow search URLs. Must be a real Zillow search URL containing searchQueryState - run your search on zillow.com and copy the address bar.

## `currentProducts` (type: `array`):

Skip the chained fetch and pass listing data directly.

## `previousProducts` (type: `array`):

Prior-run listings; used to compute changes when not in persistent monitor mode.

## `maxTotalChargeUsd` (type: `number`):

Hard maximum amount that this run may charge.

## `sources` (type: `array`):

Declare every upstream source before this run. Each item needs name, authorization, and estimated\_cost\_usd.

## `monitorEnabled` (type: `boolean`):

The first monitored run stores a free baseline. Later runs deliver and charge only new results.

## `monitorId` (type: `string`):

Pins the persistent baseline to a name of your choice, so separate targets never share state. Leave empty to derive it automatically.
