# Facts (/docs/facts)



**Facts** are stable knowledge-graph entities: companies, investment rounds, and acquisitions. They are not documents. Use them when you need deal amounts, founding dates, or canonical organization IDs.

For the documents that mention those entities, use [Proof points](/docs/proof-points). For grouped events that mix documents and facts, use [Manifestations](/docs/core-concepts/manifestations).

Each fact type exposes:

* **Search** — a page of records (`skip` / `take`, max 100)
* **Time series** — counts per bucket; investments and acquisitions also return `amounts`

All of these are `POST` with a JSON body. Date filters use calendar dates (`YYYY-MM-DD`), not datetimes.
