answers 402
Generate a finished, professional invoice PDF from JSON — recipient and line items in, a ready-to-send application/pdf out. Layouts: standard, legal, creative. Totals and tax are computed server-side so the numbers always add up. First payment auto-creates a wallet profile (token + API key in response headers); returning wallets get sequential invoice numbering and can save a sender letterhead. US
