Machine Payments Protocol

What it does

Machine Payments Protocol (MPP) is the open standard that lets AI agents pay for services programmatically.

Charge for API requests, tool calls, and content with HTTP 402 payments co-developed by Tempo and Stripe.

Verify agent identity across HTTP requests and payment retries with mppx. Delegate MPP payment validation and settlement without changing your application's payment flow. New mppx hooks connect agent runtimes to paid tools and HTTP services through MPP. Pay-as-you-go API billing is now cheaper and easier to integrate. MPP now supports generic EVM payments and x402 exact flows from onefrom mpp.dev
