GET
/api/v1/sentiment/listFree tier · 10 req/minDirectory of every sentiment index we have stored, with the latest reading for each.
Discovery endpoint. Returns the set of distinct `index_name` values in the `sentiment_index` table — e.g. `crypto_fear_greed`, `btc_dvol`, future alt-season / social indices — plus the most recent value and classification for each. Use it to build dropdowns or to detect when a new index ingestion goes live.
Query parameters
This endpoint takes no query parameters.
