Parse File (Sync)

Parse a file synchronously, waiting for the result before returning. This endpoint has a **5-minute timeout** — if processing takes longer, the request will fail. **Note:** This endpoint is intended for onboarding and testing only. For production workloads, use `POST /parse_runs` with [polling or webhooks](https://docs.extend.ai/2026-02-09/developers/async-processing) instead, as it provides better reliability for large files and avoids timeout issues. The Parse endpoint allows you to convert documents into structured, machine-readable formats with fine-grained control over the parsing process. This endpoint is ideal for extracting cleaned document content to be used as context for downstream processing, e.g. RAG pipelines, custom ingestion pipelines, embeddings classification, etc. For more details, see the [Parse File guide](https://docs.extend.ai/2026-02-09/product/parsing/parse).
