Ready for a new way to bill pay? Pay any US bill in a snap, right from your AI assistant. Describe or snap a photo of your bill (electric, water, gas, internet, phone, medical, credit card, rent, parking tickets, traffic violations and more) and Papaya reads it, then hands you a secure link to pay by card. Fast, secure, and no juggling twelve logins, with full or partial payments and status updates. Available in the US only. Powered by Papaya (papayapay.com).

Verdict only; never takes custody. Free under $10 at risk; returns an x402 payment challenge over that.
