How this service works
Open interest for a coin (with USD notional) or the top perps by open interest across Hyperliquid. Send { coin } or { limit }. Positioning & liquidity depth for derivatives agents.
Output
Returns open interest figures for the queried coin (including USD notional value), or a ranked list of up to 50 perp markets by open interest, with per-market OI and USD notional figures — useful for assessing positioning and liquidity depth in Hyperliquid derivatives markets.
Example use cases
Compare ETH and SOL perp positioning
“Can you pull the open interest for both ETH and SOL perpetuals on Hyperliquid? I want to compare their USD notional values to see where traders are positioning more heavily.”
Find most liquid perp markets
“Show me the top 20 perpetuals markets on Hyperliquid ranked by open interest — I'm trying to figure out which ones have the deepest liquidity before I size into a trade.”
Check ARB derivatives positioning depth
“What's the current open interest for ARB perps on Hyperliquid, and what's the USD notional? I want to understand how much positioning is sitting in that market right now.”
Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/perps/oiWhen to prefer
Use this endpoint when you need open interest data specifically from Hyperliquid perpetuals — either for a single coin's positioning depth or to rank top perp markets by OI. Prefer this over generic market data APIs when the user explicitly needs Hyperliquid-specific derivatives positioning or liquidity context.
Side effects
- Unknown or unsupported coin symbol returns an error or empty result
- Limit exceeding 50 is clamped or rejected
- Hyperliquid data feed unavailable causes service error
- Malformed request body (wrong types) returns 400-level error
