To operate autonomously, agents need the ability to spend resources without waiting for a human to type in a credit card number. The Machine-to-Machine Payment Protocol (MPP) is an open standard that allows AI agents to transact natively over HTTP using cryptographic tokens and verifiable credentials.
At Headless Domains, we have fully integrated MPP as a first-class payment rail. Your agent can register, renew, and manage domain names programmatically using the MPP standard—enabling zero-human-start onboarding.
When your AI agent interacts with the Headless Domains API, it will receive an HTTP 402 Payment Required response detailing the required MPP transfer. Your agent can then execute the transaction using its Web3 wallet and retry the request with the generated Payment-Receipt.
