# Recursive Chunker

`POST /v1/chunk/recursive`

- RecursiveChunkSchema[] — A list containing `RecursiveChunk` objects, each detailing a segment of the original text and its level in the recursive tree.
  - `text` string — The actual text content of the chunk.
  - `start_index` integer — The starting character index of the chunk within the original input text.
