Recipe

Mixed-format knowledge-base ingest

Inspect the file's MIME type and route to the corresponding /v1/convert/* endpoint.
For scanned PDFs where pdf-to-markdown returns empty or very low text density, fall back to /v1/convert/ocr page by page.
Post-process the returned markdown into chunks of your preferred size, embed, and write to your store.

FAQ

Conversion bundle FAQ

Can I send the file body inline or only a URL?

Both. Pass `url` for us to fetch, or `file_b64` for an inline base64 body. Inline is capped at 25 MB; URL fetches at 100 MB.

Does pdf-to-markdown preserve tables?

Yes, as markdown table syntax when the layout is recoverable. Complex multi-column layouts with merged cells degrade to plain text rows.

What OCR engine backs /convert/ocr?

Built-in OCR in our standard tier. Layout-aware OCR is in pilot on a separate worker — contact us for access.
