What is included in stock news by company and date?

headline and canonical URL, publisher, published and first-seen timestamps, company and symbol links, event tags, summary when permitted, content rights state. Coverage is reported by publisher, company, and date. Link metadata can remain public even when article body text is not licensed for redistribution.

Can I use this for historical backtesting?

Yes, where coverage and serving rights permit it. Save the query, source, known-at cutoff, schema version, and coverage result with the experiment.

What this dataset means

Stock news data connects a public article or announcement to companies and market events. Historical research needs the original publisher, canonical URL, published time, first-seen time, symbol mapping, correction state, and a clear boundary between licensed text and link metadata.

The buyer’s objective is straightforward: Retrieve relevant news for a ticker or historical event window. DataCedar keeps the research contract visible so the output can be inspected before it is trusted.

The endpoint is /v3/stocks/{symbol}/news. Responses retain deterministic pagination and the metadata needed to connect normalized records to their source run.

How to evaluate a provider

Demand stable company identity and inspect false-positive mappings; a ticker string inside an article is not sufficient entity resolution.

Publication timestamps may change and syndicated stories may duplicate one another. Historical models need first-seen time, canonicalization, and a known-at cutoff. DataCedar deliberately exposes that boundary in the product rather than leaving customers to infer it from a missing endpoint or a legal footnote.

Failure modes to test before purchase

Ticker ambiguity.
Duplicate URLs.
Future corrections leak backward.
Acquisition access is treated as proof of redistribution rights.
An empty array cannot distinguish no event from incomplete collection.

Source, freshness, and reproducibility

Source. Public publisher feeds, issuer releases, and permitted news sources. DataCedar stores source identifiers and retrieval runs before normalization, then serves its own stable downstream schema.

Freshness. Collectors poll public sources proactively and store first-seen time independently from publisher timestamps so delayed discovery is measurable.

Rights. DataCedar does not treat a crawlable article as redistributable. Full text and derived summaries are served only where ownership or license permits them.

Questions, answered.

The research schema includes headline and canonical URL, publisher, published and first-seen timestamps, company and symbol links, event tags, summary when permitted, content rights state. Fields remain connected to source, retrieval, coverage, and rights metadata.
