# v0.1.5

> Unified source parameter for Evidence Finder, Fact Checker, and Fact Search

<Update label="2026-06-23" description="v0.1.5: Unified source parameter">
  ## Changed: Unified `source` parameter across Evidence Finder, Fact Checker, and Fact Search

  `POST /api/v1/evidence-finder`, `POST /api/v1/fact-checker`, and `GET /api/v1/fact-search` now share a consistent `source` parameter for controlling which data sources are used.

  ### `source` parameter

  | Value     | Behavior                                                                                   |
  | --------- | ------------------------------------------------------------------------------------------ |
  | `default` | Public news sources only. This is the default, so there is no change to existing behavior. |
  | `ingest`  | Personal ingested knowledge base only. Requires a personal access token.                   |
  | `all`     | News + personal ingested knowledge base combined. Requires a personal access token.        |

  **Affected endpoints:**

  | Endpoint                       | Parameter | Default   |
  | ------------------------------ | --------- | --------- |
  | `GET /api/v1/fact-search`      | `source`  | `default` |
  | `POST /api/v1/evidence-finder` | `source`  | `default` |
  | `POST /api/v1/fact-checker`    | `source`  | `default` |

  **Backward compatibility:** `fact-search` previously accepted `source=news`. This value continues to work as an alias for `source=default`.
