Tools
| Tool | Description | Behaviour |
|---|---|---|
| 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 resource. Encrypted PDFs are rejected with decrypt advice (common for government blanks with an empty user password). | Changes data |
| pdf_inspect | 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_fill rejects unknown field names and over-length values. | Read-only |
| 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 already have an invoice PDF or a fillable template to populate, use pdf_fill instead. | Changes data |
| 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 unreadable or rejected input fails with an error, so a partial merge is never returned. | Changes data |
| pdfops_usage | 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. | Read-only |
