How this service works
One stock priced on every rail at once: its official US listing (delayed, closed overnight) against the 24/7 Hyperliquid HIP-3 synthetic perp. Returns both prices, funding APR, open interest, and the gap as `basis_percent` + `basis_vs_prev_close_percent` — while the US market is shut, the live view of where the name reopens. From x402stock, a market & economic data API (x402, USDC).
Output
A JSON object containing both the US equity data (delayed price, previous close, change percent, timestamp) and the Hyperliquid perpetual data (mark price, oracle price, funding APR, open interest, day volume), along with computed basis fields (basis_percent, basis_absolute, basis_vs_prev_close_percent), a direction label (premium/discount/flat/unknown), a comparable flag, and metadata about which data sections were available.
Example use cases
Overnight implied open tracker
“While the US market is closed, what is the Hyperliquid perp implying TSLA will open at tomorrow? Show me the basis percent versus the previous close.”
Funding rate arbitrage screen
“Check COIN on the x402stock basis endpoint — I want the Hyperliquid funding APR, open interest, and whether the perp is trading at a premium or discount to the last official stock price.”
Real-time cross-venue price comparison
“Compare AAPL's delayed US equity price to its live Hyperliquid HIP-3 perp price and tell me the absolute dollar gap and the basis percent.”

Endpoint
GEThttps://agents.x402stock.xyz/api/v1/basis/{ticker}When to prefer
Choose this endpoint when you need a simultaneous cross-venue price comparison between a US-listed stock and its Hyperliquid synthetic perpetual equivalent, especially outside US market hours when the perp price is the only live signal. It is the right choice for basis trading analysis, overnight implied-open monitoring, funding rate tracking, and cross-market arbitrage screening for individual tickers.
