# Daily unusual-flow sentiment

`GET /options-flow/sentiment`

## Request

- Base URL: `https://optionsbell.com/api/v1`
- URL: `https://optionsbell.com/api/v1/options-flow/sentiment`
- Auth: API key in header `X-API-Key`

Per-symbol sentiment of the day's unusual flow - call/put volumes,
premium, open interest, net delta, C/P ratios, average IV per side,
plus bullish/bearish classification with `strength_score` 0-9 and the
screener confirmations behind it. Defaults to the latest scan day;
with a range each `(symbol, date)` pair is a row. Ordered by total
premium (call + put) descending, then `date` desc, then `symbol`.

One row per symbol that had unusual flow on the day. Rows without a
signal carry `side`, `signal_type` and `strength_score` as null;
only `side` and `signal_only` exclude them. `min_strength` treats
a missing signal as 0, so `min_strength=0` is a no-op. A symbol
absent from the complete result had no unusual contract that day.
