### Tool changes
- 2026-10-18 `render_template` changed (description) **meaning changed**
- before: Render JSON data into a PDF using a built-in template: "invoice" (seller, buyer, items, tax_rate, currency) or "itinerary" (trip, days). Call GET https://rendlet.com/v1/templates for full example payloads. Counts as one document against your plan.
- after: Use when you have structured data for an invoice or travel itinerary and want a clean PDF without writing HTML. Inputs: "template" ("invoice": seller, buyer, items, tax_rate, currency; "itinerary": trip, days), "data" (object; full examples at GET https://rendlet.com/v1/templates), "filename". Output: the PDF as an embedded base64 resource plus pages and remaining quota. Same auth and 402 behaviour as html_to_pdf. Cost: 1 document from your monthly plan, or 1 prepaid credit after the cap.
- 2026-10-18 `html_to_pdf` changed (description) **meaning changed**
- before: Render an HTML string to a PDF with headless Chromium. Returns the PDF as an embedded base64 resource. Counts as one document against your Rendlet plan (Free: 100/month). JavaScript is disabled; only data: URIs and public https assets load. Simplified Chinese supported.
- after: 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 " (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.
- 2026-10-18 `preview_pdf` added
- Use to show what a document will look like before paying or signing up. Inputs: optional "html" (string, up to 50 KB; omit to preview the built-in sample invoice). Output: a 1-page low-resolution, PREVIEW-watermarked PDF (rasterized first A4 page) as an embedded base64 resource. Not for production use. Cost: free, no key, 3 previews per IP per day.
- 2026-10-18 `get_pricing` added
- Use when the user asks about price, hits a quota, or needs more documents. Inputs: none. Output: JSON with the free key, monthly plans with Stripe links, prepaid credit packs with Stripe Payment Links, the USDC-on-Base purchase endpoint and steps, and the cost of each tool. Cost: free, no key.
- 2026-10-18 `list_capabilities` added
- Use first to learn what Rendlet can render and which tools are free. Inputs: none. Output: JSON listing tools, input modes (HTML, built-in invoice/itinerary templates), page sizes, limits per plan, auth method and links. Cost: free, no key.
