## 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

## FundingPulse — Cross-Exchange Crypto Derivatives API

Real-time funding rates, open interest, long/short ratios, liquidations, and cross-exchange spread signals aggregated from **up to 6 major exchanges** — all through a single API.

A cost-effective alternative to CoinGlass ($29-699/mo) at a fraction of the price.

### What data does FundingPulse provide?

FundingPulse collects and normalizes derivatives data from Bybit, Binance, OKX, Bitget, dYdX, and Hyperliquid every 60 seconds:

- **Funding Rates** — Current and annualized rates across all exchanges for 30 perpetual pairs
- **Open Interest** — Real-time OI in contracts and USD value
- **Long/Short Ratios** — Account-level long vs short positioning
- **Liquidations** — Recent liquidation events with size and direction
- **Cross-Exchange Spreads** — The killer feature: instantly see funding rate differences between exchanges for arbitrage
- **Signals** — Pre-built funding arbitrage opportunities and composite sentiment scores

### Supported Exchanges

| Exchange | Funding | Open Interest | Long/Short | Availability |
|----------|:---:|:---:|:---:|:---:|
| OKX | Yes | Yes | Yes | All regions |
| Bitget | Yes | Yes | - | All regions |
| dYdX | Yes | Yes | - | All regions |
| Hyperliquid | Yes | Yes | - | All regions |
| Bybit | Yes | Yes | - | Region-dependent\* |
| Binance | Yes | Yes | Yes | Region-dependent\* |

\*Bybit and Binance apply geo-restrictions to their public APIs. Availability depends on the server region. When running on Apify (US servers), these exchanges may be unavailable. Self-hosted deployments from non-restricted regions will have full 6-exchange coverage.

### API Endpoints

- `GET /api/liquidations` — Recent liquidations

#### Signals & Analytics

- `GET /api/spreads` — Cross-exchange funding rate spreads for arbitrage
- `GET /api/signals/funding-arb` — Arb opportunities where spread exceeds threshold

### Use Cases

- **Funding Rate Arbitrage** — Identify spreads between exchanges where you can go long on one and short on another to capture the funding differential
- **Sentiment Analysis** — Track aggregate market positioning through funding rates, OI changes, and L/S ratios
- **Risk Management** — Monitor liquidation cascades and OI shifts in real-time
- **Trading Bot Integration** — Feed normalized multi-exchange data into your algo strategies
- **Market Dashboards** — Build derivatives dashboards with a single API call to `/api/overview`

### Authentication

Pass your API key via the `x-api-key` header:

```
curl -H "x-api-key: YOUR_KEY" https://YOUR_STANDBY_URL/api/funding-rates
```

### Technical Details

- Data refreshes every 60 seconds (funding rates, OI) and every 5 minutes (L/S ratios)
- Sub-millisecond response times via in-memory cache
- Historical data stored in SQLite with WAL mode
- All symbols normalized to canonical format (e.g., `BTC-USDT`)
- Resilient collection: one exchange failing doesn't affect others

## CLI example

```bash
echo '{}' |
apify call fraktalapi/funding-pulse --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,fraktalapi/funding-pulse"
        }
    }
}
```

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).
