A small API between you and document chaos.

Focus on retrieval and product logic. Let the conversion layer handle the messy first mile.

Keep headings, tables, reading order, and useful document metadata where the source supports them.

Choose Markdown, normalized JSON, or ready-to-ingest chunks for any vector database.

Use a direct response for small conversions or submit a job for longer-running documents.

Clear monthly allowances and explicit limits, designed for developers building production systems.

A predictable conversion layer should be easy to understand, test, and replace if your needs change.

Submit a supported file with your API request. Set the output format and conversion options.

Receive Markdown, normalized JSON, or paragraph-based chunks with source and section metadata.

Send the returned chunks to your embedding and indexing workflow, then store them in any vector database.

With API libraries for pretty much every programming language you can think of, DocuAPI fits seamlessly into any stack.

What does DocuAPI do?−DocuAPI converts supported documents into Markdown, structured JSON, or structured chunks for retrieval-augmented generation (RAG). Chunks include source and section metadata, so you can send them to your embedding model and vector database.
