# Code Chunker

`POST /v1/chunk/code`

Splits code into chunks based on its structure, leveraging Abstract Syntax Trees (ASTs) to create contextually relevant segments.

## Response `200`

Successful Response: A list of `CodeChunk` objects.

- CodeChunkSchema[] — A list containing `CodeChunk` objects, each detailing a segment of the original code and optionally the corresponding AST nodes.
  - `text` string — The actual code text content of the chunk.
  - `start_index` integer — The starting character index of the chunk within the original input code.
  - `end_index` integer — The ending character index (exclusive) of the chunk within the original input code.
  - `token_count` integer — The number of tokens in this specific chunk, according to the tokenizer used.
  - `nodes` NodeSchema[], nullable — Optional list of AST `Node` objects corresponding to this code chunk (present if `include_nodes` is true).
    - `text` string — The text content of the node.
    - `start_byte` integer — The starting byte index of the node within the original code text.
    - `end_byte` integer — The ending byte index (exclusive) of the node within the original code text.
    - `type` string — The type of the AST node (e.g., 'function_definition', 'identifier').
