# Compare stocks

`GET /reddit/stocks/v1/compare`

## Request

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

Compare up to 10 stock or ETF tickers side by side over the same UTC calendar-day period.

Results are sorted by `buzz_score` descending and return the same core analytics used by
`/trending`: `buzz_score`, `trend`, `trend_history`, `mentions`, `unique_posts`,
`subreddit_count`, `sentiment_score`, `bullish_pct`, `bearish_pct` and `total_upvotes`.
`trend` is activity momentum over the current 3 UTC days vs previous 3 UTC days using mentions, upvotes and subreddit breadth; not price movement. For `from`/`to`, anchors at `to` (or now when `to` is today).

Each requested ticker gets one row. Tickers without activity in the period, including unsupported ones, return zeroed metrics. Unsupported tickers have no company name; use `/search` to check support.

`mentions` includes inherited thread-context mentions. Use raw `/mentions` without
`include_inherited` for explicit-only rows.

## 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.
