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: overall market breadth (advancers vs decliners, advance ratio, label like 'broad_rally'), total universe count, liquid coin count, venue name, timestamp, and arrays for top_gainers, top_losers, top_volume, top_open_interest, highest_funding, most_negative_funding, and unusual_activity — each entry includes coin symbol, mark price, 24h change %, volume, open interest, funding APR, vol/OI ratio, max leverage, and premium bps.
Example use cases
Spot broad market rally or selloff
“Is Hyperliquid's perp market in a broad rally or broad decline right now? Show me the advance/decline ratio and the top 10 gainers and losers.”
Find high-funding perps for funding arbitrage
“Which Hyperliquid perpetuals have the highest positive funding rates right now? Show me the top 10 with at least $2M in 24h volume so I can evaluate funding capture trades.”
Identify unusual open interest activity
“Show me Hyperliquid perps with unusual activity or the highest open interest among the top 25 most liquid coins — I want to see which markets are seeing the biggest positioning.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/v1/nofx/oi-cap/ranking?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a ranked, multi-dimensional snapshot of Hyperliquid perpetuals market structure — covering OI, funding, volume, price momentum, and breadth — in a single call. Prefer it over generic crypto price APIs when the specific goal is Hyperliquid perp market analysis, funding arbitrage screening, or broad market sentiment assessment. Requires no API key; payment is per-call via x402 (USDC on Base).
Side effects
- Payment required (402) if x402 USDC payment on Base is not attached or fails
- Empty arrays if min_volume_usd filter is set too high and no coins qualify
- Stale data if Hyperliquid upstream API is delayed (check updated_at timestamp)
- limit exceeds maximum of 25 — returns validation error
- Invalid query parameter types cause 400-level error
