# tengu_v3_intel_options_flow_history

Historical options-flow aggregates for one ticker — the ~60s warehouse capture behind the live /intel/options_flow tool. Call when you need how flow EVOLVED (e.g. 'was NVDA flow bullish before the earnings pop?') rather than the current snapshot. Rows: as_of_ts, polarity (-1..1 net bullish/bearish score), n_alerts, premium_total (USD) + a window summary (total premium, avg polarity, bullish/bearish snapshot counts). REQUIRES date OR start(+end), max 7 days per request (422 otherwise); warehouse coverage begins 2026-05-10. 5-min cache.

## Why tengu_v3_intel_options_flow_history is rated High

tengu_v3_intel_options_flow_history triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

## Use case

AI agents invoke tengu_v3_intel_options_flow_history to trigger actions in Tengu. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Tengu:
