# 2026-05

> Factagora API releases in 2026-05 (v0.1.1)

<Update label="v0.1.1" description="2026-05-29 · Input Parameter Expansion">
  ## Input Parameter Expansion

  This release expands the input parameters across all 6 Intelligence APIs to standardize filtering, language, and result-size controls.

  **No breaking changes**: all new parameters are optional with sensible defaults. Existing requests continue to work unchanged.

  ### Added Parameters

  | Endpoint                       | New Parameters                                |
  | ------------------------------ | --------------------------------------------- |
  | `GET /api/v1/news/search`      | `from`, `to`, `domains`                       |
  | `POST /api/v1/evidence-finder` | `from`, `to`, `language`, `country`, `sortBy` |
  | `POST /api/v1/fact-checker`    | `language`, `limit`, `from`, `to`             |
  | `POST /api/v1/deep-research`   | `language`, `limit`, `from`, `to`             |
  | `POST /api/v1/timeseries`      | `language`, `limit`                           |
  | `POST /api/v1/causality-graph` | `language`, `limit`                           |

  ### Notes

  * For `news/search`, when `from` or `to` is provided, the existing `timespan` parameter is ignored (absolute range takes precedence).
  * For `news/search`, the new `domains` parameter accepts a comma-separated list of source domains to restrict results to (e.g. `bbc.com,reuters.com`).
  * The `language` parameter on `fact-checker` and `deep-research` controls the response text language; structural fields (`verdict` enum, section titles) remain in English for stable parsing.
  * For `timeseries` and `causality-graph`, the `language` parameter affects extracted labels only; timestamps and node IDs remain in their canonical formats.

  See the [API Reference](/api-reference/introduction) for the full parameter list of each endpoint.
