How this service works
Open-interest delta for one crypto perpetual on one venue — current OI against OI N hours ago. Accumulation or distribution signal: whether positioning is building or unwinding.
Output

Example use cases
Example prompt
“What's the open interest delta for BTC-USDT perps on Binance over the last 4 hours — is there net accumulation or distribution happening?”
Technical details
Endpoint
GEThttps://api.usenami.io/v1/perp/oi-deltaWhen to prefer
Use this endpoint when you need a quick directional signal on whether open interest is growing (accumulation) or shrinking (distribution) over a specific time window for a perpetual futures ticker, rather than needing a full historical timeseries. Prefer this over the historical OI timeseries endpoint when you only need the delta between now and a lookback point, not the full data series.
Side effects
- Unknown ticker or venue returns a 404 or empty result
- Lookback window too large or outside supported range returns an error
- Venue data unavailable or delayed may return stale or null OI values
- Payment not included or invalid x402 payment header results in 402 error
- Malformed input schema returns 400 validation error
