## 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

## German Building Catalog Monitor

Lagerhalle Tore is a catalog title, not a permit ID in every town.

GovData Hamburg construction catalogs (Tore, Überladebrücken). Catalogs, not a national permit firehose. $0.01.

### Last run

**4 row(s).** First row: **Einbau von 5 Toren mit vorgesetzten Überladebrücken in einer best. Lagerhalle einschl. Rückbau einer Lagerbühne**

```json
{
  "title": "Einbau von 5 Toren mit vorgesetzten Überladebrücken in einer best. Lagerhalle einschl. Rückbau einer Lagerbühne",
  "productName": "Einbau von 5 Toren mit vorgesetzten Überladebrücken in einer best. Lagerhalle einschl. Rückbau einer Lagerbühne",
  "entityName": "Einbau von 5 Toren mit vorgesetzten Überladebrücken in einer best. Lagerhalle einschl. Rückbau einer Lagerbühne",
  "listingName": "Einbau von 5 Toren mit vorgesetzten Überladebrücken in einer best. Lagerhalle einschl. Rückbau einer Lagerbühne",
  "competitorName": "Einbau von 5 Toren mit vorgesetzten Überladebrücken in einer best. Lagerhalle einschl. Rückbau einer Lagerbühne",

}
```

### Run it

Paste this on the Input tab (JSON) and press Start. That is the same input the last-run used.

```json
{
  "sourceMode": "startUrls",
  "outputMode": "buyer-ready-records",
  "maxItems": 10,
  "startUrls": [
    {
      "url": "https://www.govdata.de/ckan/api/3/action/package_search?q=Baugenehmigung%20Hamburg"
    }
  ]
}
```

### What lands in the dataset

- GovData Hamburg construction catalogs
- Live Tore / Überladebrücken row
- Not nationwide

### Use it when

Hamburg construction catalogs. Tore / Überladebrücken. Overlaps 71 — pick one.

Same buyer as rank 71 should not buy both.

### Price

**$0.01 / GovData catalog** — you pay **$0.01** per billed result. A 10-row Try is about **$0.10**.

Schedule it. A one-off curiosity click is not the product.

### What you should know

- Catalogs, not a national permit firehose.
- Overlaps rank 71.

### FAQ

**Is the last-run a fixture?** No. The JSON above is from the public source in Run it.

**National permit feed?** No. Hamburg GovData construction catalogs.

# Actor input Schema

## `buyerQuery` (type: `string`):

Buyer-safe query or scope for the records returned by this product.

## `taskIntent` (type: `string`):

Stable product-specific purpose for this saved Apify task.

## `sourceMode` (type: `string`):

Sample emits public-safe Regulatory Status Signal rows. Approved live source mode keeps the same output fields and only uses owner-approved public URLs.

## `outputMode` (type: `string`):

Use sample records for Apify Store QA or buyer-ready records for approved Regulatory Status Signal delivery.

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

Public URLs to use for live Regulatory Status Signal extraction after source-policy approval. Leave empty for sample mode.

## `requestTimeoutSecs` (type: `integer`):

Timeout applied independently to each approved source request.

## `maxRequestRetries` (type: `integer`):

Bounded retry count for transient source failures.

## `sinceLastRun` (type: `boolean`):

Uses stable Actor state to skip logical records delivered by earlier runs.

## `deltaMode` (type: `boolean`):

Preserves stable deduplication keys for recurring tasks and schedules.

# 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 = {
    "buyerQuery": "buyer-ready records with source evidence",
    "taskIntent": "buyer-ready-product-run",
    "sourceMode": "startUrls",
    "outputMode": "buyer-ready-records",
    "startUrls": [],
    "requestTimeoutSecs": 30,
    "maxRequestRetries": 2,
    "sinceLastRun": false,
    "deltaMode": true
};

// Run the Actor and wait for it to finish
const run = await client.actor("zentrafoundry/german-construction-permit-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
from apify_client import ApifyClient

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

# Prepare the Actor input

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {

            "url": "https://mcp.apify.com/?tools=fetch-actor-details,zentrafoundry/german-construction-permit-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).
