News sentiment
Per-instrument mean of the article sentiment scores /v1/news carries, one row per UTC day or Monday-starting UTC week. Each row averages the scores (-1 to 1, the same word-list tone measure as an article's sentiment.score, so most means are positive and close to 1) of the scored articles tagged to the listing and published in the bucket, each article counted once; articles without a score are left out of the mean and of article_count. A bucket is published shortly after its UTC day or week ends and recomputed over the next three days as late articles arrive, so a recent row can be revised. History reaches back as far as the stored articles. No scored article returns no row, not a neutral score. Default order: date ascending, id ascending. Omitting entity selectors returns the entitled universe; explicit unauthorized selectors return 403. Data is delivered from validated canonical batches; a connected dataset with nothing published for the key's markets yet returns 503. Access requires the operation capability on the API key.

Parameters
instrument_idsstringoptional · query- Filter by stable instrument IDs. IDs and symbols may not be combined.
symbolsstringoptional · query- Convenience lookup for exchange-listed instruments as MIC:TICKER or a bare ticker, which resolves to the exchange listing that ticker; resolves at symbol_at. The MIC and the ticker are case-insensitive, and two spellings of one listing (AAPL and XNAS:AAPL) count as a repeated value. A bare ticker that names no listing as written is also read in the common vendor spellings: with an exchange suffix (RY.TO, SHEL.L, VOD.LSE, BHP.AX), ^GSPC for INDEX:GSPC, and EURUSD=X or EURUSD for FOREX:EUR-USD. A ticker may contain a space (BAC PRL) but not start or end with one. A request in which no symbol resolves returns 404 symbol-not-resolved; otherwise each symbol that does not resolve, or resolves to a listing with no rows for the request (no-data), is an entry of meta.errors. IDs and symbols may not be combined.
symbol_atstringoptional · query- Resolve symbols as they were assigned at the end of this UTC date (YYYY-MM-DD); defaults to as_of. Only listings the security master holds resolve: it was built in September 2026 and records delistings from then on, so most issuers delisted earlier, such as TWTR or SIVB, resolve at no date. Only valid with symbols.
fromstringoptional · query- Inclusive lower bound on date.
tostringoptional · query- Inclusive upper bound on date; must be on or after from, so from equal to to selects one day.
intervalstringoptional · query- UTC buckets; default 1d.
1d1w as_ofstringoptional · query- Knowledge cutoff as a UTC date (YYYY-MM-DD): the response reflects what was known by the end of that day. Defaults to now; cannot be in the future. A date from before the dataset's knowledge history returns 422 point-in-time-unavailable naming the earliest one, which GET /v1/datasets lists as earliest_as_of.
known_fromstringoptional · query- First UTC date (YYYY-MM-DD, inclusive) on which a revision became known.
known_tostringoptional · query- Last UTC date (YYYY-MM-DD, inclusive) on which a revision became known; on or after known_from.
orderstringoptional · query- Direction on date; ties use ID ascending.
Default:ascdescasc limitintegeroptional · query- Maximum records per page.Default:
100 cursorstringoptional · query- Opaque cursor, expires after one hour; binds filters, order, resolved as_of, account/key and entitlement. Repeat the original query unchanged.
formatstringoptional · query- Response format. csv returns the data rows with a header row, for spreadsheet functions such as IMPORTDATA; nested fields become dotted columns and lists one JSON array cell, the next page cursor is returned in X-Next-Cursor and meta.errors in X-Meta-Errors. A result without rows is the header row alone, listing the documented fields of a row. Default json, or csv when format is omitted and the Accept header ranks text/csv above JSON; a format the Accept header does not admit returns 406 not-acceptable.

Response fields
Returns data as an array of records. All example values are illustrative.
idstring- Record identifier, stable across revisions.
instrument_idstring- Opaque stable public identifier; never an internal database key.
datestring- UTC bucket start date; the Monday for weekly buckets.
intervalstring- Bucket length.
1d1w article_countinteger- Number of scored articles averaged; articles without a score are not counted.
sentimentobject- sentiment
aggregationstring- Arithmetic mean of available article scores, with one contribution per article/instrument.
mean
Response metadata
Responses include meta.timezone. Dataset responses include next_cursor; health and exports have their own metadata. Request tracing uses the X-Request-ID header.
When something goes wrong
An empty data: [] is a successful query with no matching records. Invalid symbols, permissions and malformed parameters produce an RFC 9457 problem with an actionable detail.
Plans
Requires news.read. Access, recency and history depth come from the plan definitions the API enforces.

History is how far back a plan may request. How far records actually go for a symbol is history_from in dataset coverage. Nothing is real-time. Compare plans
