## 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

## OCC Options Volume & Open Interest

Daily US listed options activity from the Options Clearing Corporation, the clearing house for every US options exchange. One source covers all 18 venues.

Use it to:

- rank the most active option underlyings each day
- track put/call ratios and customer versus market-maker flow for any ticker
- map open interest by strike and expiration (call and put walls, expiry concentration)
- follow market-wide contract volume day by day

### Modes

**volume** (default): one row per underlying per day.

```json
{"date": "2026-10-15", "underlying": "SPY", "callVolume": 6598048, "putVolume": 7683566, "totalVolume": 14281614,
 "putCallRatio": 1.165, "customerCallSides": 5574156, "customerPutSides": 6263466, "firmCallSides": 99428,
 "firmPutSides": 298929, "marketMakerCallSides": 7522512, "marketMakerPutSides": 8804737, "roots": ["2SPY", "SPY"]}
```

- `callVolume` / `putVolume` / `totalVolume`: contracts traded (matches OCC's published totals)
- `*Sides`: cleared trade sides by account type (customer, firm, market maker); each contract has a buy side and a sell side
- `roots`: option roots included (adjusted roots after corporate actions are folded in)
- `byExchange: true` adds `exchanges` with call and put volume per venue

**openInterest**: one row per strike and expiration for the given underlyings, or one per expiration with `groupByExpiration`.

```json
{"underlying": "AAPL", "productSymbol": "AAPL", "expiration": "2026-10-16", "strike": 250.0,
 "callOpenInterest": 48211, "putOpenInterest": 30570, "totalOpenInterest": 78781, "positionLimit": 25000000}
```

**dailyTotals**: OCC's market-wide daily contract volume: equity options, index and other options, debt options, futures, total.

### Input

symbols, dateFrom, dateTo, byExchange, minVolume, groupByExpiration, expirationFrom, expirationTo, minOpenInterest, maxItems. See the input tab for details.

Volume for a trading day is available from OCC the same evening. Open interest reflects the most recent clearing cycle.

# Actor input Schema

## `mode` (type: `string`):

Volume by underlying (one day or a date range), open interest per strike and expiration, or OCC's market-wide daily contract totals.

## `symbols` (type: `array`):

Tickers such as AAPL or SPY. Volume: empty = every underlying, ranked by volume. Open interest: required.

## `dateFrom` (type: `string`):

YYYY-MM-DD. Volume: start of a range (up to 31 trading days with symbols, 5 without). Empty = latest trading day. Daily totals: start of range.

## `dateTo` (type: `string`):

YYYY-MM-DD end of range. Default today.

## `byExchange` (type: `boolean`):

Volume: add call and put volume per exchange.

## `minVolume` (type: `integer`):

Volume: skip underlyings that traded fewer contracts.

## `groupByExpiration` (type: `boolean`):

Open interest: one row per expiration instead of per strike.

## `expirationFrom` (type: `string`):

Open interest: earliest expiration (YYYY-MM-DD).

## `expirationTo` (type: `string`):

Open interest: latest expiration (YYYY-MM-DD).

## `minOpenInterest` (type: `integer`):

Open interest: skip strikes with fewer open contracts.

## `maxItems` (type: `integer`):

Maximum number of rows to return.

# 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 = {
    "symbols": [
        "SPY",
        "AAPL"
    ],
    "dateFrom": "",
    "dateTo": "",
    "expirationFrom": "",
    "expirationTo": ""
};

// Run the Actor and wait for it to finish
const run = await client.actor("pushbuild/occ-options-volume").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 = {
    "symbols": [
        "SPY",
        "AAPL",
    ],
    "dateFrom": "",
    "dateTo": "",
    "expirationFrom": "",
    "expirationTo": "",
}

# Run the Actor and wait for it to finish
run = client.actor("pushbuild/occ-options-volume").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 '{
  "symbols": [
    "SPY",
    "AAPL"
  ],
  "dateFrom": "",
  "dateTo": "",
  "expirationFrom": "",
  "expirationTo": ""
}' |
apify call pushbuild/occ-options-volume --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,pushbuild/occ-options-volume"
        }
    }
}
```

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).
