Would Pay Again is a newsletter about the machine-payments (x402) economy, produced by paying x402 endpoints. It sells its own ad inventory the same way: two products (classified, sponsor card), 1-4 issue bookings, one fixed-price x402 route per SKU. Storefront and live availability at GET /api/ads (free).
