## 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: Live Odds, Results & Price History

Get **live odds for any Polymarket prediction market** as clean JSON, CSV or Excel. It covers elections, crypto (Bitcoin, Ethereum), the Fed and the economy, sports, geopolitics, tech, pop culture and more.

Data comes from **Polymarket's official public APIs**. There's no login, no API key, no browser and no proxies, which is why runs are fast (usually a few seconds) and don't break when the website changes.

### What you get

For every market:

| Field | Example |
|---|---|
| `question`, `outcome` | "Will Lula win the 2026 Brazilian presidential election?", "Lula" |
| `eventTitle`, `eventSlug`, `tags` | "Brazil Presidential Election", `["Politics", "Brazil"]` |
| `impliedProbability` | `0.145`: the mid of the best bid and ask, or the Yes price if the book is thin |
| `outcomes`, `outcomePrices`, `yesPrice`, `noPrice` | `["Yes", "No"]`, `[0.145, 0.855]` |
| `bestBid`, `bestAsk`, `spread`, `lastTradePrice` | prices in dollars (0–1) |
| `priceChange24h`, `priceChange1w`, `priceChange1m` | `-0.23`: how much the odds moved |
| `volume`, `volume24h`, `volume1w`, `liquidity` | in dollars |
| `startDate`, `endDate`, `closedTime` | ISO timestamps |
| `status`, `result` | `resolved`, `"No"` for settled markets |
| `yesTokenId`, `noTokenId`, `conditionId` | IDs for Polymarket's trading API |
| `url` | a link to the market on polymarket.com |

**Optional extras:**

- **Price history** (`priceHistory`): the Yes price over the last hour, day, week, month or all time.
- **Order book** (`orderbook`): bids and asks with sizes, up to 100 levels deep.
- **Resolution rules** (`description`, `resolutionSource`).

### How to use it

**Search like the site does:** `keywords: ["bitcoin", "fed", "election"]`

**Whole topics:** `tags: ["politics", "crypto", "sports"]`

**Paste links:** `eventSlugs: ["https://polymarket.com/event/brazil-presidential-election"]` returns every outcome of that event. Use `marketSlugs` for single markets. Pair these with an Apify **schedule** to build a watchlist that updates every few minutes.

**Top markets right now:** leave everything empty and sort by 24h volume, total volume, liquidity, newest or ending soonest.

**Resolved markets for backtests:** `status: "resolved"` returns each market's winning outcome in `result`.

**Filters:**

- `minVolume`, `minVolume24h`, `minLiquidity`
- `minProbability` / `maxProbability` (e.g. only markets priced 5–95%)
- `closesWithinHours`

#### Example input

```json
{
  "keywords": ["bitcoin"],
  "status": "open",
  "minVolume24h": 10000,
  "includePriceHistory": true,
  "historyInterval": "1w",
  "maxItems": 100
}
```

### Pricing

You pay **per market returned**, and `maxItems` caps what a run can cost. Price history and order books are included at no extra charge. You also pay nothing for markets that your filters drop.

### Use cases

- **Traders and quants:** track odds, spreads and liquidity; spot big 24h moves; export history for backtests.
- **Researchers and journalists:** see what the crowd expects on elections, rates, wars or company events.
- **Cross-market arbitrage:** pair this with the [Kalshi Markets Scraper](https://apify.com/peccarvalho/kalshi-markets) to compare odds on the same event across both exchanges.
- **Dashboards and alerts:** schedule a run, then pipe the results to Google Sheets, Slack or a webhook with Apify integrations.

### FAQ

**Is this allowed?** Yes. It only reads Polymarket's public market data APIs, which Polymarket publishes for exactly this purpose. It doesn't log in or place orders.

**Why do odds look different from the site?** The site shows the midpoint when the spread is tight and the last trade otherwise. This scraper does the same, and gives you the raw bid, ask and last price so you can choose.

**Something's wrong or missing?** Open an issue on the Issues tab, and it'll be fixed quickly.

# Actor input Schema

## `keywords` (type: `array`):

Every outcome of these events, e.g. https://polymarket.com/event/brazil-presidential-election or just 'brazil-presidential-election'.

## `marketSlugs` (type: `array`):

Exact markets to track, e.g. for a scheduled watchlist.

0 to 1, e.g. 0.95. Skip markets priced above this.

## `closesWithinHours` (type: `integer`):

Only markets whose end date is within this many hours from now.

## `includePriceHistory` (type: `boolean`):

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).
