🚀 Cross-Exchange Funding Rate Arbitrage API (Apify Actor)

A production-grade quant-oriented API that scans cross-exchange perpetual funding rates to detect statistically meaningful arbitrage opportunities.

Built as an Apify Actor (Python 3.11), this tool is designed for professional traders, quants, and market-neutral strategies that rely on funding inefficiencies rather than spot price noise.

Unlike basic dashboards, this Actor:

• Normalizes funding intervals
• Annualizes rates correctly
• Flags execution and timing risks
• Outputs strict, machine-readable JSON ready for automation

---

✨ Why This Actor Exists

Funding rate arbitrage is one of the cleanest market-neutral strategies in crypto — but only if:

• Rates are normalized correctly
• Multiple exchanges are compared
• Timing drift and reliability are accounted for

This Actor is built to answer one question:

“Where is the real funding edge, right now, and how safe is it?”

🔍 Core Features

• 🔄 Cross-Exchange Funding Comparison
  • Compare funding rates across multiple CEXs
• 📈 Annualized Funding Differential
  • Converts raw funding into comparable APR values
• 🕒 Next Funding Time Awareness
  • Detects timing mismatches and drift risk
• ⚖️ Long / Short Direction Recommendation
  • Clear execution guidance per opportunity
• 🧠 Confidence & Execution Risk Scoring
  • Reliability, interval mismatch, maintenance flags
• 🧪 Async-First Architecture
  • Fast, scalable scans across large symbol sets
• 🧾 Clean JSON Output
  • No UI noise, built for APIs and bots

🏦 Supported Exchanges

Currently implemented:

• Binance (USD-M Perpetuals)
• Bybit (v5 Perpetuals)

Planned / extensible:

• OKX
• Bitget
• Gate.io
• MEXC
• Kraken

The adapter system is modular — adding new exchanges does not affect core logic.

⚙️ How It Works (High Level)

1. Discover available perpetual symbols per exchange
2. Fetch funding rate + next funding timestamp
3. Normalize funding intervals (1h, 8h, etc.)
4. Annualize funding rates
5. Detect cross-exchange divergence
6. Score confidence & execution risk
7. Output arbitrage opportunities

Method 2: API Integration

Trigger the Actor programmatically:

curl --request POST \
  --url https://api.apify.com/v2/acts/YOUR_USERNAME~funding-rate-arbitrage/runs?token=YOUR_API_TOKEN \
  --header 'Content-Type: application/json' \
  --data '{
    "symbols": [],
    "exchanges": ["binance", "bybit"],
    "min_annualized_diff_pct": 0
  }'

🧩 Input Schema

{
  "symbols": [],
  "exchanges": ["binance", "bybit"],
  "min_annualized_diff_pct": 0
}

Input Options

-   `symbols`

    -   `[]` or `["*"]` → scan all available symbols

    -   `["BTC", "ETH"]` → scan only selected symbols

-   `exchanges`

    -   List of exchanges to include

-   `min_annualized_diff_pct`

    -   Minimum APR difference to report

    -   Set to `0` for full market visibility
