Technical details
Endpoint
GEThttps://derivatives.x402tookit.com/open-interest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need open interest magnitude, OI-to-volume ratio, and OI rank for a single Hyperliquid perpetual to detect leveraged build-up. Prefer sibling endpoints for funding rate crowding, squeeze risk composite signals, or cross-venue comparisons. Use this endpoint as a focused, low-cost ($0.02) OI-specific data point rather than the full one-call snapshot.
Side effects
- Invalid or unlisted ticker symbol returns an error or null fields
- Hyperliquid data unavailable causes degraded=true with partial results
- Missing required 'coin' query parameter causes a 400-level error
- Network timeout or upstream Hyperliquid API outage returns an error response
