How this service works
Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.
Output
A JSON object containing real-time HIP-3 synthetic perpetual market data for the specified DEX and market, including: symbol, mid price, mark price, oracle price, premium, max leverage, open interest, day volume in USD and base units, previous day price, hourly funding rate, and funding APR percent — plus metadata such as venue, standard, market type, and a disclaimer clarifying this is a synthetic oracle-priced perpetual and not an official exchange close or spot price.
Example use cases
Real-time perp funding rate check
“What's the current hourly funding rate and funding APR for the NVDA synthetic perp on the xyz DEX? I want to know if it's expensive to hold a long position.”
Synthetic stock perp price monitoring
“Check the current mid price and oracle price for the NVDA HIP-3 synthetic perpetual on the xyz Hyperliquid DEX and tell me if there's a significant premium to the oracle.”
DEX perp open interest and volume snapshot
“Give me the day volume in USD and current open interest for NVDA on the xyz Hyperliquid builder DEX so I can gauge liquidity before placing a trade.”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/hip3/%7Bdex%7D/%7Bmarket%7DWhen to prefer
Use this endpoint when you need real-time synthetic perpetual (HIP-3) market data — including funding rates, open interest, and oracle-based pricing — for stocks, ETFs, or crypto assets traded on Hyperliquid builder DEXes. Prefer it over traditional stock quote APIs when you specifically need DEX perp metrics like funding rate, mark vs oracle price divergence, or max leverage for on-chain trading decisions. Not suitable for official exchange close prices or spot prices.
Side effects
- Unknown DEX or market symbol returns an error or empty result
- Market temporarily unavailable if the underlying Hyperliquid DEX is down
- Stale or delayed data if oracle feed is lagging
- Payment failure if USDC balance is insufficient or x402 payment not accepted
- Invalid path parameters result in a 400 or 404 response
