Machine Payments Protocol (MPP)
Zinc now supports the Machine Payments Protocol (MPP) — an open standard for machine-to-machine payments over HTTP. Instead of requiring API keys, subscriptions, or upfront enrollment, MPP lets AI agents pay for each order individually as part of the same HTTP request that places it.Here’s how it works: an agent calls Zinc’s order endpoint, receives an HTTP 402 payment challenge, fulfills the payment, and gets the order confirmation back — all in a single exchange. No checkout forms, no stored credentials, no human in the loop.- Stablecoin payments via Tempo — Agents can pay per-transaction using stablecoins on Tempo, with fast settlement and predictable costs
- Stripe Payment Tokens — Support for Stripe-based fiat payments via SPT coming soon
- Automatic refunds — If an order fails, the payment is automatically refunded
- Partial refunds — When the final order price is less than the agent’s
max_price, the difference is refunded
Bug Fixes

MPP support will go live early next week with Tempo and Stripe as payment methods, starting with Amazon and Zinc retailers. Stay tuned.API Key Rotation
