How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns a JSON-RPC response from the Hyperliquid protocol containing the requested on-chain data — such as market prices, order book snapshots, account positions, funding rates, or asset metadata — depending on the method called.
Example use cases
Fetch live perpetuals mid prices
“Call Hyperliquid's allMids RPC method with empty params and show me the current mid prices for all perpetual markets.”
Check account open orders
“Use the Hyperliquid RPC to call 'openOrders' with my address '0xAbC123...' as the param and list all my current open orders.”
Retrieve funding rate data
“Query Hyperliquid via RPC using the 'metaAndAssetCtxs' method so I can see the current funding rates and open interest across all perp markets.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/hyperliquid/rpc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic access to Hyperliquid perpetuals DEX data (market prices, positions, orders, funding rates) without running your own Hyperliquid node, and you want pay-per-call micropayment billing via x402 USDC rather than a subscription API key.
Side effects
- Invalid or unsupported RPC method name returns an error response
- Malformed params array causes a parsing error
- Payment not attached results in HTTP 402 response requiring x402 payment
- Hyperliquid node unavailable causes upstream timeout or 503
- Rate limiting if call volume exceeds gateway thresholds
