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
Returns a JSON object with: a verdict (e.g. BALANCED, CROWDED), a human-readable action recommendation, reasons array explaining the signal, open interest in USD across OKX and Hyperliquid with 1h/4h/24h percentage changes, liquidation counts and USD amounts for longs and shorts across 1h/4h/24h windows, taker buy/sell flow ratios, long/short ratio with 48h percentile context, funding rates (OKX 8h % and APR, Hyperliquid APR), a crowding score, and next suggested endpoint calls.
Example use cases
Crowding check before a short trade
“Before I short BTC, can you check if longs are already getting squeezed — give me the OI change over the last 4 hours, liquidation breakdown, and a verdict on whether positioning is crowded or balanced?”
Funding rate arbitrage scan
“What's the current funding rate for ETH on Hyperliquid versus OKX, and is open interest rising or falling? I want to know if there's a funding arb opportunity.”
Deleveraging alert for SOL perps
“Check SOL perpetuals right now — is there any sign of deleveraging? I want the 4h OI change, recent long vs short liquidations, and the taker buy/sell ratio.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/v1/coinank/oi/kline?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI trading agent needs a pre-packaged positioning verdict that aggregates OI, liquidations, taker flow, and funding rates into a single actionable signal — especially when the agent needs to decide whether to fade or follow a move. Prefer this over raw exchange APIs when you want multi-venue aggregation (OKX + Hyperliquid) with no API key management, paid per-call via USDC on Base via x402.
Side effects
- Unknown coin symbol returns an error or empty data
- Coinank upstream data lag may cause stale OI or liquidation figures
- Very low-liquidity coins may have missing venue data
- x402 payment failure if USDC balance on Base is insufficient
- Rate limits or worker timeouts on high-traffic coins during volatile markets
