# Per-ticker news-flow sentiment + attention

`GET /api/v1/equities/{symbol}/news-sentiment`

Primary news-flow sentiment + attention for a ticker, entirely from Sugra-owned sources: GDELT tone + volume timelines and the 43-feed first-party RSS ingest, entity-linked via the SEC registrant name + former names (so coverage filed under an old name is still matched). This is editorial NEWS-FLOW sentiment, the defensible alternative to scraped social mention-counting - it does not capture retail crowd psychology or pre-news buzz. Cached 10min (GDELT's update cadence). Not investment advice.

## Path parameters

- `symbol` string, required — Company ticker symbol.

## Query parameters

- `timespan` string — GDELT lookback window.

## Response `200`

Sentiment (GDELT average document tone) and attention (coverage volume + first-party article count) time series for the company, plus recent first-party headlines.

- EnvelopeNewsSentimentData
  - `data` NewsSentimentData, required — DATA-9.6: per-ticker news-flow sentiment + attention from owned sources.
    - `symbol` string, required
    - `company_name` string, required
    - `former_names` string[]
    - `cik` string, nullable — SEC CIK of the resolved filer. Null when the registry could not be reached.
    - `match_basis` string — What the headlines were matched on. 'entity' = the registered legal name and its former names. 'symbol' = the bare ticker, used when the registry was unreachable; precision is lower, and much lower for tickers that are ordinary words (ALL, IT, ON, KEY, CAR, GO).
    - `entity_unavailable_reason` string, nullable — Null when the SEC registry answered. A reason string when it did not, in which case company_name falls back to the symbol and former_names is empty because it could not be looked up - not because the company never had another name (BUG-36).
    - `query` string, required — The entity query (current + former names) used.
    - `timespan` string, required
    - `sentiment` SentimentBlock, required
      - `latest_tone` number, nullable
      - `average_tone` number, nullable
      - `timeline` TimelinePoint[]
        - `date` string, required
        - `value` number, required
      - `scale` string, required
      - `unavailable_reason` string, nullable — Null when tone was measured. A reason string when the tone source could not be reached, so a null tone with a reason is never read as neutral sentiment (BUG-33).
    - `attention` AttentionBlock, required
      - `timeline` TimelinePoint[] — Coverage-volume time series.
        - `date` string, required
        - `value` number, required
      - `first_party_article_count` integer
      - `unavailable_reason` string, nullable — Null when coverage volume was measured. A reason string when the source could not be reached, so an empty series with a reason is never read as an absence of coverage (BUG-33).
    - `recent_headlines` NewsHeadline[]
      - `title` string, nullable
      - `source` string, nullable
      - `published` string, nullable
      - `url` string, nullable
    - `source` string
    - `note` string, required
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
