## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## 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

### Actor Orchestrator (KV to KV)

Give it a KV store with keys and values, and it will run an actor/task for each key with its contents as input then save it to another store.

This actor is pretty lightweight, so it should be able to run on 128MB of memory for as long as you need without any problems.

#### Behavior

- Reads all keys from the input store
- Calculates the number of concurrent runs based on the available memory for you as a user and the `maxConcurrency` input. It will try to use half of all the maximum memory.
- Creates an amount of concurrent runs, each running the actor/task for a key from the input store.
- When a run finishes, it saves the result to the output store.
- When a run fails, it logs the error to its dataset.
- When all runs are finished, it exits.

It keeps track of the current status of each run in a key-value store. So if you restart it or it migrates, it will pick up where it left off.

#### Common usage

1. Set up a named KV store for the inputs.
2. Push data to be processed to the KV store.
3. Set up a named KV store for the results.
4. Run the actor.

You can also set up this actor to run on a schedule. (Recommended)
Remember to not have more than one run of this actor running at the same time.

# Actor input Schema

## `requestStoreId` (type: `string`):

ID of the request store to consume requests from.

## `polygonStoreId` (type: `string`):

ID of the polygon store to store geojson polygon results.

## `targetActor` (type: `string`):

Actor to run.

## `targetTask` (type: `string`):

Task to run.

## `maxMemoryGbytes` (type: `integer`):

Maximum memory to use, in gigabytes.

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

Maximum number of concurrent requests to process.

## `actorRunMemoryMbytes` (type: `integer`):

Memory to use for the actor run, in megabytes.

## Actor input object example

```json
{
  "maxMemoryGbytes": 8,
  "maxConcurrency": 5,
  "actorRunMemoryMbytes": 2048
}
```

# 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("aysen/kv-to-kv-orchestrator").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
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("aysen/kv-to-kv-orchestrator").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}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call aysen/kv-to-kv-orchestrator --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,aysen/kv-to-kv-orchestrator"
        }
    }
}
```

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).
