Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/v1/orderbook?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs real-time Hyperliquid perpetual orderbook data (not just a single mid price) and wants configurable depth — especially useful for pre-trade slippage estimation, market-making quote setting, or spread monitoring. It requires no API key setup, just x402 USDC micropayment on Base, making it ideal for autonomous agents that self-pay per call. Prefer this over generic price feeds when you need L2 book structure (multiple levels), not just a spot price.
Side effects
- Payment not included or invalid x402 USDC payment → 402 Payment Required
- Unsupported coin symbol → validation error or default fallback to BTC
- Depth out of range (< 1 or > 20) → schema validation error
- Hyperliquid upstream API unavailable → 502/503 or stale data
- Network timeout from Cloudflare Worker → 524 timeout
