How this service works
See where the real leverage sits so you are not on the wrong side — the ten symbols carrying the largest open-interest notional
Output
A ranked list of the ten perpetual futures symbols carrying the largest open-interest notional, giving a snapshot of where leverage is most concentrated across the crypto derivatives market at the time of the call.
Example use cases
Avoiding overleveraged crowded markets
“Before I open a new position, show me which ten perp markets have the most open interest concentration — I don't want to be on the wrong side of a crowded unwind.”
Pre-trade macro leverage check
“What does the OI concentration landscape look like across crypto perps right now? I want the top ten symbols by open-interest notional before the New York open.”
Risk desk monitoring crowding signals
“Pull the current top-ten OI concentration ranking for crypto perps — I'm checking whether any of our existing positions are in the most crowded markets.”
Technical details
Endpoint
GEThttps://whale-signals.whalesignals.workers.dev/data/oi-concentration?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pre-parsed top-10 ranking of crypto perpetuals by open-interest notional without having to query and aggregate multiple exchange APIs yourself. Prefer it over raw exchange APIs when you want a single, clean signal-desk view of leverage concentration, especially in an automated trading or risk-monitoring workflow that runs on a per-call micropayment model.
Side effects
- Upstream data source unavailable — empty or error response if the underlying exchange/aggregator feed is down
- Stale data — OI figures may lag by seconds to minutes depending on the refresh cycle
- Payment failure — x402 micropayment not processed, call rejected before data is returned
- Empty result set if no OI data is available for the current time window
