# Crypto Open Interest & Positioning Signal

> Crypto Open Interest & Positioning Signal is a paid API for AI agents from kr-x402-mvp.kgy5612.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).

Returns real-time open interest, liquidations, taker flow, long/short ratio, and a crowding verdict for a given crypto perpetual coin

## 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 crypto-open-interest-positioning-signal-51c26381
```

Example prompt: What's the current open interest and positioning verdict for BTC — are longs getting liquidated heavily and is the market crowded enough to fade?

## When to prefer this

Choose this endpoint when an AI trading agent needs a fast, consolidated crowding and positioning signal for crypto perps — combining OI, liquidations, taker flow, and funding in one call — without managing multiple exchange API keys. Ideal for pre-trade sanity checks, mean-reversion signal generation, or monitoring for liquidation cascades. Prefer over raw exchange APIs when you want a pre-interpreted verdict and action recommendation rather than raw numbers.

## Known failure modes

- Invalid or unsupported coin symbol returns an error or empty result
- Payment failure (x402 USDC on Base) results in 402 response before data is returned
- Stale data if upstream OKX/Hyperliquid feeds are delayed — updated_at field should be checked
- No coin param defaults to BTC — missing coin param does not error but may return unexpected coin
- Rate or venue data may be partial if one exchange feed is temporarily unavailable

## How this service works

Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.

## Output

A JSON object containing: the coin's total and per-venue open interest in USD with 1h/4h/24h % changes, long liquidation and short liquidation amounts across 1h/4h/24h windows with dominant side, taker buy/sell volumes and ratio, long/short ratio with 48h percentile context, funding rates (OKX APR and Hyperliquid APR), a crowding_score, a human-readable verdict (e.g. BALANCED), a plain-English action recommendation, bullet-point reasons, and suggested next endpoints to call.
