What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of api.pdf-api.xhub.io controls every word below.

Generate a PDF from a template

Render a PDF document by merging a JSON data object into a block-based template. Reference a stored template by id or post an inline template. Returns the binary PDF.

pdfrendertemplatedocumentreport
Examples it gives
  • Generate a monthly report PDF from my report template and this data
  • Render a confirmation letter PDF from an inline template
  • Create a PDF from template 00000000-0000-4000-a003-000000000001 with this data

Attach files to a PDF

Embed one or more files as attachments into an existing PDF without re-rendering it. Preserves PDF/A-3 conformance when the carrier is already PDF/A-3.

pdfattachmentembedpdf/a-3
Examples it gives
  • Attach this CSV to my PDF
  • Embed the source XML into this PDF report
  • Add a supporting document to a generated PDF

List the form fields of a PDF

Inspect the fillable AcroForm fields of a PDF and return their names, types, options, and required/read-only flags — so you know which keys to send when filling it.

pdfformacroforminspectfields
Examples it gives
  • What fields can I fill in this PDF?
  • List the form fields of this application form
  • Show me the AcroForm schema of this document

Fill the form fields of a PDF

Fill the AcroForm fields of a PDF from a map of field name → value and return the resulting PDF. Optionally flatten the form so the values are baked in and no longer editable.

pdfformacroformfillflatten
Examples it gives
  • Fill this PDF form with these values
  • Fill and flatten this application form
  • Set the name and date fields in this PDF and lock them
