# BTC Perpetual Funding Rate Cross-Venue Aggregate

> BTC Perpetual Funding Rate Cross-Venue Aggregate is a paid API for AI agents from nonvisceral-eloisa-mousily.ngrok-free.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Aggregates BTC perpetual funding rates across 8 major exchanges, providing per-venue APR divergence, max dispersion in bps, squeeze-setup detection, and a contrarian funding direction verdict.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nonvisceral-eloisa-mousily-ngrok-free-dev-724c4de4
```

Example prompt: What's the current BTC funding rate picture across all major exchanges — is it long-skewed, short-skewed, or diverging, and which venue is the outlier with the highest dispersion?

## When to prefer this

Prefer this endpoint when you need cross-venue BTC funding rate synthesis rather than a single-exchange feed — especially for detecting funding squeeze setups, identifying which venue is an outlier, computing max dispersion in bps, or getting a contrarian directional verdict that single-venue APIs cannot provide. Ideal for systematic trading agents that need a single aggregated signal across Binance, Bybit, OKX, Bitget, Coinbase, Hyperliquid, Kraken, and MEXC simultaneously.

## Known failure modes

- Upstream exchange APIs unavailable — reduced reachable_venues count with partial data
- ngrok tunnel downtime — connection refused or 502 gateway error
- Stale data if exchanges throttle — updated_at timestamp may lag
- Payment failure (x402) — 402 response if USDC payment not provided

## How this service works

Cross-venue BTC perpetual funding aggregated across 8 exchanges (Binance/Bybit/OKX/Bitget/Coinbase/Hyperliquid/Kraken/MEXC). Per-venue %APR divergence, max-dispersion in bps, contrarian funding-hunt direction, verdict (long-skew/short-skew/neutral/diverging). Squeeze-setup detector single-venue feeds miss.

## Output

Returns a JSON object with aggregate annualized funding rate (% APR), per-venue funding rates and their divergence from the aggregate (in % APR and per-hour), max dispersion in basis points, the max-divergence venue details, the number of reachable venues (up to 8: Binance/Bybit/OKX/Bitget/Coinbase/Hyperliquid/Kraken/MEXC), a contrarian funding-hunt direction signal, a verdict string (long-skew/short-skew/neutral/diverging), and an updated_at timestamp.
