## Pricing

from $2.00 / 1,000 results

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower 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`).

## Polymarket Leaderboard Scraper

> **Thirdwatch portfolio:** 5K users across 97 public Actors, 2M+ records delivered, and >99% run success. [Explore all Thirdwatch Actors](https://apify.com/thirdwatch).

Scrape Polymarket's public leaderboard — ranked traders with realized PnL, trading volume, verified status, X handles, and proxy-wallet addresses across daily, weekly, monthly, and all-time windows.

Use it for smart-money tracking, whale watching, copy-trading research, and prediction-market analytics.

### Why this Actor

- **Public leaderboard API:** clean JSON, no auth.
- **All windows:** `day`, `week`, `month`, and all-time periods.
- **PnL or volume ranking:** `orderBy` chooses the ranking metric.
- **Identity fields:** username, profile image, verified flag, linked X handle, and proxy wallet for on-chain follow-up.

### Quick start

```json
{
  "timePeriod": "month",
  "orderBy": "pnl",
  "limit": 50
}
```

### Input

| Field | Required | Description |
|---|---:|---|
| `timePeriod` | No | `day`, `week`, `month`, or `all`. Default: `month`. |
| `orderBy` | No | Rank by `pnl` or `volume`. Default: `pnl`. |
| `limit` | No | Max traders. Default: 50. |

### Output

| Field | Description |
|---|---|
| `rank` | Leaderboard position. |
| `userName`, `xUsername` | Display name and linked X handle. |
| `proxyWallet` | On-chain wallet address. |
| `pnlUsd`, `volumeUsd` | PnL and volume for the window. |
| `verified`, `profileImage` | Verification flag and avatar. |
| `timePeriod`, `orderBy` | The window and metric used. |

### Notes & limitations

- PnL/volume are Polymarket's own reported figures for the selected window.
- Anonymous accounts show a wallet with no `userName`.

# 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("thirdwatch/polymarket-leaderboard-scraper").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
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("thirdwatch/polymarket-leaderboard-scraper").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():

## CLI example

```bash
echo '{}' |
apify call thirdwatch/polymarket-leaderboard-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,thirdwatch/polymarket-leaderboard-scraper"
        }
    }
}
```

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).
