POST
Regenerates text content for a single slide. The service keeps the original text-element structure and only replaces content, so positional and style metadata remain intact.

Path Parameters

string
required
Slideshow UUID.
number
required
Zero-based slide index (0, 1, 2, ...). Must be a non-negative integer.

Body Parameters

string
Optional rewrite instruction (1-500 chars), for example "Make it punchier".
Empty body is valid ({} behavior). In that case the API generates a subtle variation automatically.

Preconditions

  • Slideshow must be in draft status.
  • Slideshow must have original_prompt.
  • Target slide index must exist.
  • Target slide must contain at least one text element.
