How this service works
First-party Hyperliquid trading intelligence: perp fills, position lifecycles, all-wallet leaderboards, trader cohorts, liquidation risk and HIP-4 prediction markets - computed from our own node_fills ledger plus the Hyperliquid public info API (no third-party data source). Free discovery (/healthz, /v1/stats, /.well-known/x402, /v1/openapi.json) and free sample routes (/v1/markets/overview, /v1/assets); all other API calls are $0.001 USDC per request via x402 on Base (no account, no API key).
Output
Returns official open interest figures for Hyperliquid perpetual markets, computed from the operator's own node_fills ledger. Typically includes per-asset OI values, aggregate market OI, and associated metadata such as market identifiers — all sourced first-party from Hyperliquid's on-chain data rather than a third-party aggregator.
Example use cases
Track BTC perp OI spike
“Check the official open interest for BTC perps on Hyperliquid right now — I want to see whether OI has spiked in the last session.”
Compare OI across top assets
“Pull the official open interest across all Hyperliquid perp markets and rank the assets by OI so I can see where capital is concentrated.”
Risk dashboard OI snapshot
“Give me a snapshot of official open interest across Hyperliquid perpetuals so I can update my risk dashboard with the latest node-level figures.”
Technical details
Endpoint
POSThttps://hyperliquid-data.v1337.org/v1/markets/official-oiWhen to prefer
Choose this endpoint when you need authoritative, first-party open interest data sourced directly from Hyperliquid's node_fills ledger rather than aggregated third-party feeds. Ideal when accuracy of OI figures matters for risk management, trading signal generation, or market analysis dashboards. Prefer over general crypto data APIs when Hyperliquid-specific official OI is required with no reliance on external data sources. At $0.001 USDC per call via x402, it suits automated agents that need on-demand OI snapshots without account setup.
