InvoiceInvoice-pdfInvoice-generatorBillingPdf-generation

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. USD only.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
