Parse files **asynchronously** to get cleaned, chunked target content (e.g. markdown). The Parse Async 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. Parse files asynchronously and get a parser run ID that can be used to check status and retrieve results with the [Get Parser Run](https://docs.extend.ai/2025-04-21/developers/api-reference/parse-endpoints/get-parser-run) endpoint. This is useful for: * Large files that may take longer to process * Avoiding timeout issues with synchronous parsing. For more details, see the [Parse File guide](https://docs.extend.ai/2025-04-21/product/parsing/parse).
