Latest reading for a single sentiment index, looked up by name.

Thin companion to `/sentiment/list`. When you already know the index you want, this returns only the newest sample — cheaper than hitting the history endpoint with `limit=1`. An unknown name resolves to `{ latest: null }` with `meta.unavailable = "no-data"` (a 200, not a 404), so the client UX stays uniform.

Path parameters

Segments of the URL path, validated server-side.

Query parameters

This endpoint takes no query parameters.

Response shape

Always wrapped in the standard envelope. Nullable fields are explicitly marked — treat missing numeric data as a real data-source gap, not as an error.

// Wrapped in the standard envelope:
// {
//   data: /* shape below */,
//   meta?: { total?: number; limit?: number; offset?: number; ... }
// }

{
  indexName: string;
  source: string | null;
  latest: { ts: number; value: number; classification: string } | null;
}

Example

Copy the curl, replace YOUR_KEY with a real key from your dashboard, and run.

curl -sS "http://localhost:3000/api/v1/sentiment/crypto_fear_greed"

{
  "data": {
    "indexName": "crypto_fear_greed",
    "source": "alternative.me",
    "latest": { "ts": 1744761600000, "value": 62, "classification": "Greed" }
  },
  "meta": { "total": 1 }
}

Notes

• Pair with `/sentiment/{index}/history` when you also need the chart series.
