## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Polymarket Scraper

Scrape Polymarket prediction markets, events, order books, trades, and tags via public APIs. No auth, no browser, no captchas.

### Features

- **Markets** — Fetch prediction markets with prices, volume, liquidity, outcomes, and resolution status
- **Events** — Fetch event groupings (multiple markets under one question)
- **Order Books** — Full bid/ask order book data for any market
- **Trade History** — Recent trades with prices, sizes, and trader info
- **Tags** — Discover all available categories for filtering

All data comes from Polymarket's public Gamma, CLOB, and Data APIs. No authentication required.

### Input

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `mode` | string | Yes | `markets`, `events`, `orderbook`, `trades`, or `tags` |
| `queries` | array | No | Market/event slugs (leave empty to bulk-fetch all) |
| `limit` | integer | No | Max results (default: 100) |
| `closed` | boolean | No | Fetch closed/resolved markets instead of active (default: false) |
| `order` | string | No | Sort field: `volume24hr`, `volume`, `liquidity`, `startDate`, `endDate`, `createdAt` |
| `ascending` | boolean | No | Sort ascending (default: false = highest volume first) |
| `includeOrderBook` | boolean | No | Fetch full order book for each market (default: false) |
| `tagId` | integer | No | Filter by tag/category ID |
