  title: LLMWhisperer Extraction Webhooks API
  description: 'LLMWhisperer (by Unstract / Zipstack) is a document-to-text extraction API that converts PDFs, scanned documents, and images into clean, layout-preserving text ready for large language models. The v2 API is asynchronous: submit a document to POST /whisper, poll GET /whisper-status, then fetch the result with GET /whisper-retrieve. GET /highlights returns per-line bounding-box coordinates and /whisper-manage-callback manages webhook callbacks. All requests authenticate with the unstract-key header.'
