Once the server is connected, just ask in plain
English — the agent picks the tools. The examples below show the typical tool
path so you know what each question costs and where the answer comes from.
Unusual activity
Were there any unusual bullish sweeps on TSLA today?
flow_search (confirm ticker) → sweeps and/or unusual_volume, filtered to
calls. The agent summarizes premium, venues, and Flow Score.
Which tickers had the most unusual options volume this week, excluding the indices?
unusual_volume with exclude_tickers=SPY,QQQ,IWM — or top_contracts_weekly
for a premium-ranked list.
Directional read on a name
Is the flow on NVDA bullish or bearish right now, and how strong?
aggregate_score (Composite + VWF/SDF/FIR across timeframes), often paired with
flow_momentum for a “vs baseline” read and chain_bull_bear to separate call
buying from put selling.
Show me where the premium is concentrated by strike on SPY this afternoon.
flow_strikes (or by_strike) over the session window.
Positioning & accumulation
Is the OTM call activity on AMD new positioning or closing flow?
vol_oi (accumulation score + new-position estimate) and unusual_oi
(opening vs closing direction).
What does the AAPL chain look like for the Jan 17 expiration?
expirations (find the date) → option_chain for that expiration.
Market-wide
What’s the overall market tone today — risk-on or risk-off?
market_breadth for the one-line read, market_overview and market_tide for
the supporting detail.
Which sector is seeing the strongest call flow?
market_breadth (per-sector rotation) → sector_flow to drill into the leader.
Dealer positioning (Heatseeker)
Where are the gamma walls on SPY right now?
heat_heatmap for the current per-strike gamma exposure + live velocity.
What did the SPY gamma profile look like at the open on March 5?
heat_historical_heatmap with at=2026-03-05T14:30:00Z.
Combining both products
SPY has a gamma wall at 600 — is the flow defending it or pushing through?
heat_heatmap (locate the wall) → flow_strikes / flow_tide around that strike
to see whether premium is accumulating into or fading away from it. This pairing —
positioning from Heatseeker, intent from Flowseeker — is the core reason the two
products share one gateway and one key.
