Frequently Asked Questions

What is the Machine Payments Protocol?

MPP is an open standard that uses HTTP 402 (Payment Required) to let AI agents pay for API services. Instead of needing API keys and accounts, agents can discover pricing, negotiate payment, and access services programmatically. It was launched by Stripe and Tempo in March 2026.

How does MPP work?

When an AI agent calls an MPP-enabled API, the service responds with HTTP 402 and a JSON body specifying the price, accepted payment methods, and a payment URL. The agent completes payment and retries the request with a payment receipt. The service validates the receipt and fulfils the request.

Which companies back MPP?

As of March 2026, MPP is backed by Stripe, Visa, Mastercard, Anthropic, OpenAI, DoorDash, Shopify, Revolut, Ramp, Cloudflare, Nubank, Standard Chartered, and Lightspark. More companies join regularly.

Is MPP free to use?

There is no cost to implement MPP. It is an open protocol. Individual payment methods may charge transaction fees (e.g., blockchain gas fees, card processing fees), but MPP itself is free and open-source.

What payment methods does MPP support?

MPP supports stablecoins via Tempo, credit/debit cards via Visa, Bitcoin Lightning via Lightspark, and traditional card payments via Stripe. The protocol is payment-method agnostic, and new payment rails can be added via extensions.
