How this service works
Invoicing and billing resources sold per call to software. POST invoice JSON to check it (0.05 USD), get a print-ready A4 invoice as PDF (0.10 USD) or as self-contained HTML (0.10 USD), or GET the FreelanceDesk app and document pack as zip downloads. Each endpoint answers 402 with two payment options: an x402 v2 PAYMENT-REQUIRED challenge and an MPP WWW-Authenticate challenge (method evm, intent charge). Both settle an exact USDC EIP-3009 transfer on Base (eip155:8453) and return the resource in the same response.
Output
Returns a PDF file as a download with metadata: the filename (e.g. invoice-2026-014.pdf), the computed invoice total, the currency, and the content type (application/pdf). The PDF is a formatted A4 print-ready invoice document.

Technical details
Endpoint
POSThttps://afraid-butterfly-5236.obtranzat.deno.net/v1/invoice/pdf?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a professionally formatted, print-ready A4 PDF invoice and are comfortable paying per-call in USDC on Base via x402 or MPP. Prefer this over the HTML sibling when the output must be printed, emailed as an attachment, or archived as a fixed-layout document. Use the cheaper /validate endpoint first to check the invoice JSON before paying for the PDF render.
