List the industry-specific invoice templates available on Blank Invoice Maker (https://blankinvoicemaker.com). Returns each template's slug, name, description, and page URL. Use this to discover templates; build a custom invoice with create_invoice.

Create a professional invoice and return a link that opens it — fully pre-filled — in the free Blank Invoice Maker editor (https://blankinvoicemaker.com). No signup, no watermark. The user opens the link to review and download the PDF; all invoice data stays in their browser (it travels in the link's URL fragment and is never sent to a server).
