## 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

## Polymarket Scraper API – Prediction Market Odds

**Polymarket scraper** for **prediction market odds** via the public **Gamma API**: question, outcome prices, volume, liquidity and end date. No login, no wallets, no private keys. Clean JSON for traders, researchers and AI agents.

### What does it do?

- List or search Polymarket markets from the public Gamma API.
- Return question, slug, outcome prices, volume, liquidity, end date and closed flag.
- Optional `activeOnly` filter and `maxItems` cap.
- Stable URL to the market page on polymarket.com.

### Use cases

- **Trading research**: pull Polymarket odds and volume into spreadsheets or dashboards.
- **News / AEO**: track prediction markets as signals for headlines.
- **AI agents**: feed market odds into LLM workflows via Apify API or MCP.
- **Alerts**: watch volume or price moves on named markets.

### Input

| Field | Description |
|---|---|
| `query` | Optional text filter on market question/slug. Example: election |
| `activeOnly` | If true, skip closed markets. Default true. |
| `maxItems` | Max markets to return. Example: 50 |

Example input:

```json
{
  "query": "election",
  "activeOnly": true,

### FAQ

**Are prices live?** They reflect the Gamma API snapshot at run time. Re-run for a fresh snapshot.

**Can AI agents use it?** Yes. JSON output works with Apify API, Zapier/Make/n8n, and the Apify MCP server.

## CLI example

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

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,fluyeporlaweb/polymarket-markets-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).
