How this service works
Use when an agent needs the best live price for a stock across venues before trading. For 1-10 tickers: perp mark and mid on trade.xyz (Hyperliquid), Aster, Lighter and OKX, xStocks and Ondo token prices per share, last US close, the session reference price, gap % vs it, cross-venue spread, best bid/ask and freshness. Unpaid calls get 402; bad or unknown tickers get 400/404 before any charge. Errors: 400, 402, 404, 502. Data, not advice.
Output
A JSON object per ticker containing: perp mark price and mid from each listed venue (Hyperliquid/trade.xyz, Aster, Lighter, OKX), xStocks and Ondo token prices per share, last US close, session reference price, gap percentage versus reference, cross-venue spread, best bid and best ask, US session label (pre/regular/after-hours/overnight), and data freshness timestamps. Errors return JSON with an error string and optional hint.
Example use cases
Pre-trade price check for single stock
“I'm about to buy TSLA on trade.xyz — can you grab the current perp mark and mid, the gap vs last US close, and the best bid/ask across all venues so I can see if I'm getting a fair price?”
Multi-ticker arbitrage scan
“Pull live quotes for NVDA, AAPL, and MSFT across Hyperliquid, Aster, Lighter, and OKX — I want to see the cross-venue spread and gap percentage for each so I can spot the best arb opportunity.”
Tokenized stock price comparison
“I'm deciding between xStocks and Ondo for an AMZN position — show me both token prices per share, the current perp mark, and how they all compare to the last US close and session reference price.”
Technical details
Endpoint
GEThttps://perp-gap-api.perpgap.workers.dev/quote?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a consolidated, real-time best-price view across multiple tokenized stock and perp venues (Hyperliquid, Aster, Lighter, OKX, xStocks, Ondo) for 1–10 tickers before executing a trade. Prefer it over single-venue APIs when cross-venue spread, gap analysis, or venue selection is part of the decision. Not suitable for historical data, order execution, or non-stock assets.
Side effects
- 400 – Bad or malformed ticker parameter (never charged)
- 402 – Payment required; call was unpaid or payment failed
- 404 – Ticker or market not listed on any tracked venue (checked before settlement, never charged)
- 502 – Upstream venue data unavailable or error fetching live prices
