## 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`).

## Fear and Greed Index API – Crypto History

**Fear and Greed Index API** for crypto: today’s value or **full history** (0–100) with classification from **Alternative.me**. No login. JSON for traders, dashboards and AI agents.

### What does it do?

- Fetch the crypto Fear and Greed Index for recent days or longer history.
- Return date, timestamp, value (0–100), classification and source URL.
- Cap rows with `limit` / `maxItems`.

### Use cases

- **Trading dashboards**: chart Fear and Greed next to price.
- **Alerts**: notify when the index enters Extreme Fear / Greed.
- **Research**: download history for backtests.
- **AI agents**: inject market-sentiment context via MCP.

### Input

| Field | Description |
|---|---|
| `limit` | How many recent daily index points to request. Default 30. |
| `maxItems` | Hard cap on rows written to the dataset. Default 1000. |

Example input:

```json
{
  "limit": 30,
  "maxItems": 30
}
```

### Output

Real output (sample from a prior run on 27 Oct 2026, Europe/Madrid):

```json
[
  {
    "date": "2026-10-27",
    "timestamp": "1793059200",

## CLI example

```bash
echo '{}' |
apify call fluyeporlaweb/crypto-fear-greed-scraper --silent --output-dataset

```

## MCP server setup

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