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.
Example use cases
Pre-trade crowding check for BTC
“Before I open a long on BTC perps, check the current open interest and tell me if the market is crowded or if there's a crowding extreme I should be aware of.”
ETH liquidation cascade detection
“Are there heavy long liquidations happening on ETH right now? Show me the 1h and 4h liquidation breakdown and taker flow so I can decide whether to step in.”
SOL positioning divergence across venues
“Pull the open interest and long/short ratio for SOL perps and tell me if there's a big divergence between OKX and Hyperliquid funding rates — I want to see the crowding verdict.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/v1/crypto/open-interest?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
