# Crypto Funding Rates & Open Interest Tracker (`foxlabs/crypto-funding-rates`) Actor
Track crypto perpetual funding rates & open interest across exchanges (CoinGecko) — filter by coin, exchange & min open interest, or compare funding rates across exchanges (cross-exchange spread). US-safe, flat CSV/Excel, no API key. Powered by CoinGecko.

## What's an Apify Actor?
Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.
Actors are written with capital "A".
## 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.
The best way to integrate Actors is as follows.
In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):
```bash
npm install apify-client
```
In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):
```bash
pip install apify-client
```
In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):
````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash
In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).
If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).
For usage examples, see the [API](#api) section below.
For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

## Crypto Funding Rates & Open Interest Tracker
**Funding rates and open interest for crypto perpetuals & futures — across every major exchange, plus a cross-exchange funding-rate comparison.** Clean, filterable CSV/Excel rows from the free CoinGecko derivatives data.
**US-safe:** CoinGecko relays the data, so this never calls a geo-blocked exchange API (Binance/Bybit/OKX work from Apify's US servers). **No API key, no proxy.**
---
### Two modes
**1. Tickers** — one row per market: funding rate, open interest, 24h volume, basis & price. Filter by coin, exchange, contract type and minimum open interest; sort by OI, funding rate (highest or most extreme), or volume.
**2. Funding comparison** — one row per coin showing the **cross-exchange funding-rate spread**: the highest-funding venue vs the lowest, the spread between them, and total open interest. A starting point for spotting funding dislocations between exchanges. Defaults to major exchanges only — because a spread is only meaningful across liquid venues.
> Honest note: exchanges report funding on different intervals (1h / 8h / annualized) and this actor does **not** normalize them, so the spread is **indicative, not a clean arbitrage** — confirm each venue's funding convention before acting.
| Coin | Spread | Max funding | Min funding |
|---|---|---|---|
| BTC | 0.22 | HTX | Deribit |
---
### Quick start
```json
{
"mode": "tickers",
"coin": "BTC",
"minOpenInterest": 1000000,
"sortBy": "open_interest",
"maxResults": 500
}
````
**Presets to try:**
- **BTC funding across exchanges** — `mode: tickers`, `coin: BTC`
- **Highest funding (squeeze hunt)** — `mode: tickers`, `sortBy: funding_rate`
- **Funding comparison** — `mode: spread` (major exchanges, ranked by spread)
- **One exchange only** — `exchange: "Binance"`
No API key, no proxy, no setup.
***
### Output fields
**Tickers:** `rank, indexId (coin), symbol, market (exchange), contractType, fundingRate, openInterest, volume24h, basis, spread, price, priceChange24hPct`
**Spread:** `rank, indexId, fundingSpread, maxFundingRate, maxFundingExchange, minFundingRate, minFundingExchange, exchangeCount, totalOpenInterest, avgPrice`
### Why this actor
- **Funding + OI + cross-exchange comparison in one feed** — the things perp traders watch, filterable and schedulable.
- **Junk filtered out** — a sanity cap drops broken/illiquid exchanges reporting nonsense rates; spread mode restricts to major venues so the comparison is meaningful.
- **US-safe & free** — built on CoinGecko's relay, so no geo-blocks, no key, no proxy.
- **Schedulable** — re-run on a cron for a live funding/OI dataset into a sheet, bot or model.
> **Data source:** Powered by [CoinGecko](https://www.coingecko.com). Funding-rate values are passed through as CoinGecko reports them; smaller exchanges can report unreliable rates, so filter by exchange / open interest for the cleanest signal. Provided as-is for research, not financial advice.
***
### Changelog
#### 0.1.0 — 2026-06-05
- Initial release: crypto funding rates & open interest across exchanges from the free CoinGecko derivatives API — tickers mode (per market) + funding-comparison mode (cross-exchange spread), junk-rate sanity filter, major-exchange filter, US-safe, flat CSV/Excel, no API key.

# Actor input Schema
## `mode` (type: `string`):
"Tickers" = one row per market (funding rate, OI, volume). "Funding comparison" = one row per coin showing the cross-exchange funding-rate spread (highest vs lowest funding venue). Note: exchanges report funding on different intervals, so the spread is indicative, not a normalized arbitrage.
## `coin` (type: `string`):
Filter to one coin by its index symbol (e.g. "BTC", "ETH", "SOL"). Leave empty for all.
## `exchange` (type: `string`):
Keep only markets whose exchange name contains this (e.g. "Binance", "Bybit", "OKX"). Leave empty for all.
## `contractType` (type: `string`):
Filter by contract type.
## `minOpenInterest` (type: `integer`):
Drop illiquid markets below this open interest. Defaults to 1,000,000 to filter out junk/low-liquidity exchanges — set to 0 to include everything.
## `minVolume24h` (type: `integer`):
Only include markets with at least this 24h volume. 0 = no filter.
## `maxAbsFundingRate` (type: `number`):
Drop markets whose absolute funding rate is above this — a sanity filter for broken/illiquid exchanges reporting nonsense rates. Default 1 (real rates cluster near 0). Set 0 to disable.
## `onlyMajorExchanges` (type: `boolean`):
Keep only well-known liquid venues (Binance, Bybit, OKX, Bitget, Gate, MEXC, Kraken, Deribit, Hyperliquid…). Defaults ON in spread mode (the comparison is only meaningful across liquid exchanges), OFF in tickers mode.
## `sortBy` (type: `string`):
How to rank rows in tickers mode.
## `maxResults` (type: `integer`):
Cap the number of rows returned.
