## 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

## Dutch B2B Contract Wage and CPI Indexation Calculator

Statutory Dutch contract indexation from official CBS CAO wage and CPI OData tables with audit citation.

### Who it's for

B2B contract managers, facility services providers, commercial landlords, procurement officers, and corporate controllers in the Netherlands who need to calculate statutory annual contract indexation without manual CBS StatLine lookups or spreadsheet disputes.

### What you get

Accurate contract adjustments calculated directly from official keyless CBS StatLine OData feeds (Table 85663NED for CAO wages and Table 83131NED for CPI). The tool outputs the exact percentage adjustment, new contract amount, base and target index points, revision status as CBS publishes it per period (definitive or provisional), and a citation string ready for invoices. Wage indices use the current figures (huidige cijfers), not the first-published ones.

Supported formulas include:

- `cao_hourly_incl`: Hourly CAO wages including special allowances (standard for facility and professional services)
- `cao_hourly_excl`: Hourly CAO wages excluding special allowances
- `cao_monthly_incl`: Monthly contractual wage index
- `cpi`: Consumer Price Index (all expenditure categories)
- `blended_80_20`: Weighted formula (80% CAO hourly wage + 20% CPI) widely used in Dutch logistics and service contracts

Errors are never charged.

### Limits

- Covers official CBS indices from 2020 onwards (base year 2020=100 for CAO wages, 2015=100 for CPI).
- Strictly deterministic; no user data or contract terms are stored after execution.
- Maximum 120 seconds execution time per request.

### How to use

- **Run it** in Apify Console or through the API: choose what to do, fill in the fields for that tool and start. The result is one item in the run's dataset.
- **From an AI assistant** through Apify's MCP server (mcp.apify.com), which finds and runs this Actor with the same fields. What each choice does:
  - `calculate_indexation`: Calculate statutory contract indexation from official CBS StatLine OData feeds.
  - `list_sectors`: List standard Dutch SBI 2008 economic sector codes supported by CBS table 85663NED.

### Pricing

- Calculate B2B Contract Indexation via CBS CAO Wages and CPI: $0.88

Failed calls are never charged.

# 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 = {};

// Run the Actor and wait for it to finish
const run = await client.actor("eloquent_mountain/cao-index-nl").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 = {}

# Run the Actor and wait for it to finish
run = client.actor("eloquent_mountain/cao-index-nl").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}")

## CLI example

```bash
echo '{}' |
apify call eloquent_mountain/cao-index-nl --silent --output-dataset

```

## MCP server setup

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

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).
