  • html_to_pdfUse to produce a real, full-quality PDF from HTML (reports, receipts, letters).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use to produce a real, full-quality PDF from HTML (reports, receipts, letters). Inputs: "html" (required), "format" (A4|Letter|Legal|A3|A5), "landscape", "margin" (CSS length), "filename". Rendered by headless Chromium with JavaScript disabled; only data: URIs and public https assets load; Chinese text supported. Output: the PDF as an embedded base64 resource plus pages, bytes and remaining quota. Requires "Authorization: Bearer <key>" (or "sandbox" for a watermarked 1-page trial, 5/day). Without a usable key it returns a 402 payment_required result with buy links. Cost: 1 document from your monthly plan (free key: 100/month), or 1 prepaid credit after the cap.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: false
  • render_templateUse when you have structured data for an invoice or travel itinerary and want a clean PDF without writing HTML.No findings
