# Onchain Query API – Crypto Perpetual Futures Snapshot

> Onchain Query API – Crypto Perpetual Futures Snapshot is a paid API for AI agents from chain.cyberwarex.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

## 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 onchain-query-api-crypto-perpetual-futures-snapshot-811ea98e
```

Example prompt: What's the current funding rate, mark price, open interest, and long/short ratio for BTC perpetual futures right now?

## When to prefer this

Choose this endpoint when you need a one-call, aggregated derivatives view for a crypto asset — especially when you need funding rate, open interest, and long/short ratio together without assembling multiple Binance API calls. Ideal for funding arbitrage decisions, leverage/positioning reads, or when onchain-only data sources lack derivatives coverage.

## Known failure modes

- Unknown or unsupported symbol returns null fields or an error
- Symbol not available on Binance USD-M returns empty or null data
- Network/cache timeout may return stale data beyond the 30s cache window
- Malformed symbol input (e.g. wrong format) may return an error response
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Crypto perpetual-futures snapshot for a symbol in ONE call (Binance USD-M, keyless): current funding rate and the next funding time, mark and index price, open interest (contracts and USD), 24h price change/high/low/volume, and the top-trader long/short account ratio. For funding arbitrage, leverage/positioning reads, and a derivatives view an onchain-only feed cannot give. Cached 30s.

## Output

A JSON object containing: the perpetual symbol, funding rate, annualized funding rate percentage, next funding timestamp (Unix ms), mark price, index price, open interest in contracts and USD, 24h high/low/volume and price change percent, and the top-trader long/short account ratio. Data is sourced from Binance USD-M and cached for 30 seconds.
