# Market sentiment

`GET /polymarket/stocks/v1/market-sentiment`

## Request

- Base URL: `https://api.adanos.com`
- URL: `https://api.adanos.com/polymarket/stocks/v1/market-sentiment`
- Auth: API key in header `X-API-Key`

Returns one reading for all stock-related Polymarket activity: overall buzz, sentiment split, activity trend, breadth and the `drivers` behind it, ranked by `buzz_score`.

Here `buzz_score` compares overall Polymarket stock-market activity with its own trailing 90-day baseline:
- around `50` = normal market activity
- higher = more active than usual
- lower = quieter than usual

`trend` is flow momentum over the current 3 UTC days vs previous 3 UTC days using trades, volume, market breadth and liquidity; not price movement. For `from`/`to`, anchors at `to` (or now when `to` is today).

Use `sentiment_score`, `bullish_pct` and `bearish_pct` for direction.

## Query parameters

- `from` string, date, nullable: Start date in YYYY-MM-DD. Inclusive UTC date.
- `to` string, date, nullable: End date in YYYY-MM-DD. Inclusive UTC date. Omit to use the current UTC date.
