# Get topic distances for a word query across all models (JSON)

`GET /topics.json`

Tokenizes query `q` (supports multiple tokenizer modes in server config), computes topic distances/similarities across all available models, merges and sorts, then returns an array of objects with: - `k`: model size (number of topics) - `t`: topic index - `distance`: distance/similarity value

## Query parameters

- `q` string, required

## Response `200`

Array of (model, topic, distance) results

- WordTopicDistanceItem[]
  - `k` integer, required — Model size (number of topics).
  - `t` integer, required — Topic index within model.
  - `distance` number, float, required — Distance/similarity value (as computed by server).
