Response

The PDF, or a ZIP of the PDFs when you send several.

The route also takes the headers. An error answers a status and a message: see Errors.

Tag an existing PDF​

curl \
  --request POST http://localhost:3000/forms/pdf/autotag \
  --form files=@report.pdf \
  -o report.pdf

/forms/pdf/info then answers "tagged": true. A PDF you make tags better at the source, from its HTML or its document: Chromium and LibreOffice take nativeTaggedPdf. For PDF/UA, remediate the PDF, which tags it too.

In a list of stages​

The stage also runs in a list on /forms/pdf/pipe, and on the PDFs a Chromium or LibreOffice conversion makes, in its stages field:

curl \
  --request POST http://localhost:3000/forms/pdf/pipe \
  --form files=@report.pdf \
  --form 'stages=[
    { "op": "autotag" }
  ]' \
  -o report.pdf
