pdf_inspectread-only

List a PDF's AcroForm form fields — names, types, options, current values, per-field maxLength where declared — plus a paste-ready fillTemplate object for pdf_fill and a hasXFA flag (hybrid AcroForm/XFA inputs lose their XFA layer when filled). A PDF with no fillable form returns count 0. Read-only: the PDF is fetched but never modified. Call this FIRST when filling an unfamiliar PDF, since pdf_fi

pdf_fill

Fill AcroForm form fields in a PDF and return the result. Field names must exist in the PDF (use pdf_inspect first). All values are strings; checkboxes take "true"/"false"; dropdown/radio/optionlist values must be one of the field's options; text values must respect the field's maxLength from pdf_inspect. The source PDF is never modified. Returns the filled PDF inline as an application/pdf resourc

pdf_merge

Merge two or more PDFs into one, in the order given, and return the result. Sources are read only and never modified. Returns the merged PDF inline as an application/pdf resource. This tool only concatenates whole documents: it does not reorder, rotate or delete pages within them, and it does not fill forms — use pdf_fill for a fillable form and pdf_invoice to build a document from data. An unread

pdf_invoice

Generate a complete, professionally laid-out invoice PDF from structured data — no template needed. Deterministic: the same input produces byte-identical output (safe to re-run). Note: without a paid PDFops key the output carries a small "Generated with pdfops.dev" footer line. Returns the invoice inline as an application/pdf resource. Use this when you have invoice DATA and no document; if you al

pdfops_usageread-only

Check the current PDFops API quota for the configured key: tier, limit, used, remaining, the billing period, and the reset timestamp. Read-only and safe to call before a batch to confirm there is headroom. Uses the API key this connection authenticated with.
