## Pricing

from $30.00 / 1,000 new matched source events

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## 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

## RSS Content Deduplicator & Material Change Feed

Turn an explicit public RSS/Atom allowlist into canonical new-item and material-correction events without duplicate billing.

### buyer job

Recurring exception monitoring from Publisher-provided RSS or Atom feeds; bounded source and event caps, a silent first-run baseline, and deterministic replay prevent surprise output and duplicate charges.

### pricing

- `rss-canonical-item-new` — `$0.03`
- `rss-content-deduplicator-source-correction` — `$0.01`

Unchanged, empty, failed-source, and silent-baseline runs produce zero paid events. Every event links to its source and carries a SHA-256 source fingerprint.

# Actor input Schema

## `watchlistId` (type: `string`):

Stable URL-safe identifier that scopes replay state.

## `feedUrls` (type: `array`):

Explicit public-source allowlist or match terms for this recurring job.

## `baselineMode` (type: `string`):

Choose a free silent baseline or emit current matches as paid events.

## `maxEvents` (type: `integer`):

Hard cap on paid events emitted by one run.

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

Hard cap on pay-per-event charges for one run.

## `maxSourceRecords` (type: `integer`):

Hard cap on source records fetched and evaluated per run.

## `stateStoreName` (type: `string`):

Named key-value store used for deterministic replay suppression.

## `resetState` (type: `boolean`):

Discard prior replay state; may cause current matches to emit again.

## `qualityTestMode` (type: `boolean`):

Apify Store automated smoke-test mode. It validates runtime and input startup, emits one unbilled summary, and does not query sources, mutate state, deliver business events, or charge.

## Actor input object example

```json
{
  "watchlistId": "rss-content-deduplicator-watch",
  "feedUrls": [
    "https://github.blog/feed/"
  ],
  "baselineMode": "silent",
  "maxEvents": 1,
  "maxTotalChargeUsd": 1,
  "maxSourceRecords": 100,
  "stateStoreName": "quality-test-rss-content-deduplicator",
  "resetState": false,
  "qualityTestMode": true
}
```

# 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 = {
    "watchlistId": "rss-content-deduplicator-watch",
    "maxEvents": 1,
    "maxSourceRecords": 100,
    "stateStoreName": "quality-test-rss-content-deduplicator",
    "qualityTestMode": true
};

// Run the Actor and wait for it to finish
const run = await client.actor("frankycheese/rss-content-deduplicator").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 = {
    "watchlistId": "rss-content-deduplicator-watch",
    "maxEvents": 1,
    "maxSourceRecords": 100,
    "stateStoreName": "quality-test-rss-content-deduplicator",
    "qualityTestMode": True,
}

# Run the Actor and wait for it to finish
run = client.actor("frankycheese/rss-content-deduplicator").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 '{
  "watchlistId": "rss-content-deduplicator-watch",
  "maxEvents": 1,
  "maxSourceRecords": 100,
  "stateStoreName": "quality-test-rss-content-deduplicator",
  "qualityTestMode": true
}' |
apify call frankycheese/rss-content-deduplicator --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,frankycheese/rss-content-deduplicator"
        }
    }
}
```

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).
