How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
A JSON object containing an array of assets, each with: asset symbol, mark (brand) price, oracle price, basis in basis points, premium percentage, open interest in USD, hourly funding rate, and annualized funding rate. Also includes a source attribution and an explanatory note about funding direction conventions.
Example use cases
Funding arbitrage opportunity scanner
“Which Hyperliquid perpetual markets currently have the most extreme funding rates — positive or negative — and what's the basis in basis points? Show me the top 30 by annualized funding rate so I can evaluate cash-and-carry trades.”
Long-position cost monitoring
“I'm long several Hyperliquid perps and want to check how much I'm paying in funding right now. Pull the hourly and annualized funding rates for all assets and flag any where funding is above 50% annualized.”
Open interest market overview
“Give me a snapshot of the Hyperliquid perp market — I need open interest in USD, the oracle vs mark price spread, and current funding rates for all listed assets so I can see where the most activity and price dislocation is happening.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/hyperliquid-basis?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need comprehensive, per-asset Hyperliquid perpetual market data including basis, funding rates, and open interest in a single call. Prefer this over manually querying Hyperliquid's public API when you need pay-per-call access without API key management, or when building an agent that needs structured funding rate and basis data for trading signal generation or risk monitoring.
Side effects
- Invalid or unsupported currency filter returns empty asset list
- Limit parameter exceeding available assets returns all available assets
- Hyperliquid data source temporarily unavailable returns an error or stale data
- Malformed request body returns 400 validation error
- Payment failure via x402 prevents call execution
