## Pricing

from $0.50 / 1,000 processed job records

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

## Job Feed Deduplicator

Merge duplicate job records from multiple feeds without collapsing conflicting
requisitions. The output keeps stable canonical jobs, clean apply URLs, source
provenance, and match confidence.

### Start in 30 seconds

1. Select **Try for free** and run with no input for a labeled demo.
2. Supply job records from authorized job boards, aggregators, or ATS exports.
3. Export the canonical dataset for search, analytics, or downstream feeds.

**Price:** $0.0005 per supplied job record, plus a $0.00005 start event.
Demo runs are free, and billing is never based on duplicates removed.

The Actor keeps records separate when requisition identities conflict or the
evidence is insufficient.

### Features

- **Tracking Stripping**: Normalizes marketing & tracking parameters (`utm_*`, `ref`, `gh_src`, `from`, etc.) from apply URLs while preserving functional requisition routing.
- **Entity Normalization**: Standardizes company names (removes corporate suffixes like Inc, LLC, Ltd) and job titles (standardizes seniority like Sr/Jr, levels, removes bracketed req numbers).
- **Safe Merging**:
  - **Never merges on an absent key alone**: Missing companies, titles, or locations are not treated as wildcards.
  - **Multi-city protection**: Distinct physical locations for the same company and title are preserved as distinct job requisitions.
- **Full Provenance & Confidence**: Each canonical job links back to all contributing source postings with an explicit match confidence rating (`exact`, `high`, `medium`, `low`).
- **Zero-Network Execution**: Runs completely offline and deterministically without external API dependencies.

### Input

Input is provided via the standard Apify Actor input or by specifying a local fixture file:

```json
{
  "jobs": [
    {
      "id": "gh-1",
      "source": "greenhouse",
      "title": "Senior Backend Engineer",
      "company": "Stripe, Inc.",
      "location": "San Francisco, CA",
      "applyUrl": "https://boards.greenhouse.io/stripe/jobs/5829101?gh_src=indeed"
    },
    {
      "id": "ind-1",
      "source": "indeed",
      "title": "Sr. Backend Engineer",
      "company": "Stripe",
      "location": "San Francisco, CA",
      "applyUrl": "https://boards.greenhouse.io/stripe/jobs/5829101?utm_source=indeed"
    }
  ]
}
```

Or reference a local fixture:

```json
{
  "fixturePath": "fixtures/seeded-jobs.json"
}
```

### Output

Canonical job records are pushed to the default dataset:

```json
{
  "canonicalId": "can_f8a9e7b2104c95d3",
  "title": "Senior Backend Engineer",
  "normalizedTitle": "senior backend engineer",
  "company": "Stripe, Inc.",
  "normalizedCompany": "stripe",
  "locations": ["San Francisco, CA"],
  "isRemote": false,
  "canonicalApplyUrl": "https://boards.greenhouse.io/stripe/jobs/5829101",
  "matchConfidence": "exact",
  "matchReasons": ["exact_apply_url_match"],
  "sourceCount": 2,
  "sources": [ ... ]
}
```

Deduplication summary statistics are written to the default Key-Value Store under the `OUTPUT` record.

### Local Development & Testing

Run the test suite:

```bash
npm test
```

Run against local fixture:

```bash
npm start
```

Customer input can contain nonpublic requisitions. Minimize fields, preserve
source references, and delete run datasets under your chosen retention policy.

# Actor input Schema

## `jobs` (type: `array`):

Array of raw job posting objects from job boards, scrapers, or ATS feeds.

## `fixturePath` (type: `string`):

Optional local file path to load JSON job fixtures from (for testing and offline execution).

## Actor input object example

```json
{
  "jobs": []
}
```

# Actor output Schema

## `canonicalJobs` (type: `string`):

Deduplicated canonical job postings with provenance and match confidence.

## `runOutput` (type: `string`):

Summary of deduplication metrics: input records, canonical records, duplicates removed, and match confidence counts.

# 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("mehdi_badawi/job-posting-deduplication").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("mehdi_badawi/job-posting-deduplication").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 mehdi_badawi/job-posting-deduplication --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,mehdi_badawi/job-posting-deduplication"
        }
    }
}
```

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).
