description: funding-arb.api.klymax402.com provides a single scanning service that compares perpetual futures funding rates across Hyperliquid, Binance, Bybit, and OKX to surface cross-venue arbitrage opportunities. It ranks results by annualized yield and assigns long/short venue pairs for delta-neutral carry trades. Output includes the best opportunity, total assets scanned, and a cache TTL.

# funding-arb.api.klymax402.com

This host is a narrow, purpose-built tool for traders and agents executing delta-neutral funding rate arbitrage across major perpetual futures venues. It does one thing: aggregate funding rates from four exchanges, compute cross-venue spreads, and return ranked opportunities with actionable long/short assignments. It does not provide single-venue rate lookups, spot pricing, or DeFi yield data.

## When to use this host

Use this host when an agent needs to identify delta-neutral carry trades by comparing funding rates across Hyperliquid, Binance, Bybit, and OKX in a single call. Do not use it for single-venue funding rate lookups — use perp_get_funding_rates instead. Do not use it for spot or DEX swap pricing — use dex_get_swap_quote instead. Do not use it for DeFi yield farming opportunities — use defi_find_best_yields instead. Because this host has only one skill, there are no multi-step workflows; it is best used as a signal source feeding downstream execution or position-sizing logic on other hosts.

## Capabilities

### Cross-Venue Funding Rate Arbitrage

Scans perpetual futures funding rates across Hyperliquid, Binance, Bybit, and OKX simultaneously, computes cross-venue spreads, and returns ranked delta-neutral carry trade opportunities with annualized yield estimates and venue assignments.

- **`scan-funding-rate-arbitrage`** — Scans perpetual futures funding rates across Hyperliquid, Binance, Bybit, and OKX to identify cross-venue arbitrage opportunities ranked by annualized yield.

## Skill reference

### `scan-funding-rate-arbitrage`

**Funding Arb Scanner** — Scans perpetual futures funding rates across Hyperliquid, Binance, Bybit, and OKX to identify cross-venue arbitrage opportunities ranked by annualized yield.

*Use when:* Use when an agent needs to identify delta-neutral carry trades by finding assets where funding rates diverge significantly across perpetual exchanges, returning ranked opportunities with long/short venue assignments and estimated annualized returns.

*Not for:* Do not use for single-venue funding rate lookups — use perp_get_funding_rates instead. Do not use for spot or swap prices — use dex_get_swap_quote instead. Do not use for DeFi yield farming — use defi_find_best_yields instead.

**Inputs:**

- `symbol` (string) — Filter results to a specific asset symbol (e.g. BTC, ETH, SOL). If omitted, all available assets are scanned.

**Returns:** Returns a ranked list of cross-venue funding rate arbitrage opportunities with long/short venue assignments, spread, annualizedYield, bestOpportunity summary, venuesOnline array, totalAssetsScanned count, and a 30-second cache TTL.
