How this service works
Bullflow.io is a real-time unusual options flow and dark pool tracker with advanced tools to view, filter, and analyze market activity as it happens.
Output
Returns a JSON object with cumulative call net premium and put net premium data points as a time series array, each point containing a Unix timestamp, callsNetPremium (USD), and putsNetPremium (USD). Also includes metadata: ticker, period, from/to dates, bucket_seconds, point_count, and filter flags (sweeps_only, include_multileg, sweeps_filtered_count, multilegs_filtered_count).
Example use cases
Intraday options sentiment dashboard
“Get me the net call and put premium series for SPY for today — I want to see how bullish versus bearish options flow has shifted minute by minute throughout the trading session.”
Weekly sweep flow analysis for NVDA
“Fetch the 7-day net premium time series for NVDA from Bullflow, sweeps only, so I can analyze whether institutional sweep activity has been predominantly bullish or bearish this week.”

Technical details
Endpoint
GEThttps://api.bullflow.io/v1/data/netPremiumSeries?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cumulative net premium time-series data (calls vs puts) for a specific ticker to gauge options market sentiment or flow direction over time. It is distinct from raw flow feeds — it aggregates premium into directional buckets over configurable periods (1D to MAX), making it ideal for charting or trend analysis. Prefer it over generic market data APIs when you specifically need options-flow-derived sentiment signals with sweep and multileg filtering.
Side effects
- Missing required 'ticker' query parameter returns an error
- Invalid period enum value outside allowed set causes rejection
- Providing 'from' without 'to' (or vice versa) may return an error or default behavior
- Ticker not supported or not found returns empty points array
- Date range outside available data returns zero point_count with empty points array
- Non-trading day or after-hours request may return empty data for 1D period
