## 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

***Get location data including city and municipality from Norwegian postal codes (zip codes).***

Simply provide a list of postal codes and get back structured location data for each one.

No login required. No cookies needed. Pay-per-event pricing.

### Why Choose This Actor?

**"Enrich your data with Norwegian location information in seconds"**

Our Norway Postal Code / Zip Code Search provides:

- **Very Fast Responses**: Parallel processing for large batches
- **Cost-Effective**: Pay only for the postal codes you need: `$2.00 / 1k postal codes`
- **Complete Data**: Get city, municipality code, municipality name, and category

### Quick Start

1. Open the actor on Apify and go to the **Input** tab.
2. Paste the example input below (or edit the prefilled list).
3. Click **Start** and wait for the run to finish.
4. Open the **Output** (dataset) tab to view or export the results as JSON, CSV or Excel.

```json
{
  "postalcodes": ["0001"]
}
```

Example output item:

```json
{
  "postalcode": "0001",
  "city": "OSLO",
  "municipality_code": "0301",
  "municipality_name": "OSLO",
  "category": "P",
  "error": null
}
```

### Usage Examples

#### Resolve a Single Postal Code

```json
{
  "postalcodes": ["0001"]
}
```

#### Resolve Multiple Postal Codes

```json
{
  "postalcodes": ["0001", "5003", "7010"]
}
```

Returns one record per postal code found, with the same fields as the example output item in Quick Start (here three records, for 0001, 5003 and 7010).

### Input Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `postalcodes` | array | Yes | - | List of Norwegian postal codes (zip codes) to resolve (4 digits each). 1-1000 per run; duplicates are ignored, invalid or too many codes fail the run |

### Output Fields

| Field | Type | Description |
|-------|------|-------------|
| `postalcode` | string | 4-digit Norwegian postal code |
| `city` | string | City/place name |
| `municipality_code` | string | 4-digit municipality code |

|------|-------------|
| $0.0001 / start | Charged per actor run |
| $2.00 / 1,000 postal codes | Charged per postal code returned |

### API Integration

#### Python

```python
from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")

run = client.actor("bite-sized-insights/norwegian-postalcode-to-city-name").call(
    run_input={
        "postalcodes": ["0001", "5003", "7010", "9990"]
    }
)

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(f"{item['postalcode']}: {item['city']}, {item['municipality_name']}")
```

#### JavaScript

```javascript
import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });

const run = await client.actor('bite-sized-insights/norwegian-postalcode-to-city-name').call({
    postalcodes: ['0001', '5003', '7010']
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach(item => {
    console.log(`${item.postalcode}: ${item.city}, ${item.municipality_name}`);
});
```

### Use Cases

## MCP server setup

```json

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).
