Machine Payments Protocol

Introducing the Machine Payments Protocol: an open standard for machine payments co-authored by @tempo and @stripe MPP is designed to be extensible and payment-method agnostic, already supporting stablecoins, cards, and more.

Hermes supports the MPP agent skill. This means your agent can use pay-per-call APIs over MPP with configurable safety limits; no human needed. Tempo is purpose-built for payments, including agentic transactions:

We've published an official @USDC method spec for @mpp (Machine Payments Protocol) The spec gives developers: → A standardized way for agents to transact in USDC across supported EVM chains and Solana → The first crosschain payment profile in MPP via Circle Gateway → Support for USDC-backed stablecoins, starting with USDCx on Stacks For blockchain networks, this creates a path to become a settlement layer for machine-to-machine commerce, enabling seamless USDC payments between agents, APIs, services, and merchants across chains. paymentauth.org/draft-usdc-cha…

0x Swap API now supports autonomous agent payments. Agents call 0x Swap API and pay $0.01 per request in USDC from their own wallet. No API key required. Built with @Alchemy's AgentPay.

The way for machine-to-machine streaming payments to scale is ______. Listen to @brendan_j_ryan (@tempo) break down the framework

Agents are transacting on behalf of users, stablecoins have made sub-penny payments feasible, and protocols like x402 and MPP are turning API endpoints into paid resources. The infrastructure for internet-native commerce is being built in real time. Micropayments never took off because paying for things one at a time adds friction. Agents don't have that problem, which means the entire model for how content and data gets monetized on the internet is about to shift. Michael (@blauyourmind) breaks down why the buyer changing from human to agent is what is making pay-per-use work on @TheDryRunPod.

Here's me walking you through our new Stripe Directory and how we see it being used! Check it out and send us feedback: stripe.directory

and here's miles, product lead on @stripe directory, with a detailed walkthrough =>

Humans and agents can now discover and pay Stripe businesses with the @Stripe Directory This includes how to pay the business over @mpp machine payments, support in projects.dev, and more All you need is a public Stripe profile!

Introducing Stripe Directory, a new way for you (and your agents) to search for businesses on the Stripe network.

Excited for agents and humans to find our customers in the @stripe Directory! We help merchants like Martin Estate and Sayer and Stone onboard to @mpp. Directory helps these merchants with more discoverability.

Introducing MPP Credits. Fund your agent using Tempo Wallet with credit or debit cards, Apple Pay, or Google Pay, then spend at MPP-enabled APIs. MPP credits are issued by @CoinflowLabs, with merchants settling in stablecoins on Tempo under the hood. tempo.xyz/blog/mpp-credi…

We have partnered with the @Tempo and @Privy_io team at @Stripe to support MPP on all APIs on Orthogonal. Tempo is a purpose-built L1 from Stripe and @Paradigm. Sub-second finality, stablecoin-native gas, built for agent commerce. What agents can do with MPP on Orthogonal: - Transact across any rail (stablecoins, cards, Lightning) through one endpoint - Deposit once, transact thousands of times off-chain via sessions - No API key needed. Just a wallet. By listing on Orthogonal our API partners now become openly accessible to any agent with a wallet that supports MPP. All endpoints are now discoverable on MPP Discover Services catalog.

1,000,000 free requests per month, per agent, now available with @MPP on Quicknode. No account, no API keys. Pay with a stablecoin and query 140+ networks. Refreshes every month.

Build on Tempo and MPP with free @Quicknode requests

At Stripe, we're empowering agents to become buyers We launched @mpp with our friends at @tempo to enable businesses to programmatically sell to agents Excited to see Mastercard invest in agent-led payments, and looking forward to working with them on MPP!

Agentic commerce needs open standards at the protocol layer and open settlement rails underneath. We're excited to work with @Mastercard to make their new Agent Pay service compatible with the Machine Payments Protocol (@mpp), with Tempo providing stablecoin settlement for agent-driven payments at scale.

Visa is for vibe coders. Anyone can spin up an app and any API can become a merchant. Starting today we’re onboarding x402 and MPP merchant endpoints into Visa CLI so APIs, LLMs, data products, and dev tools can be discovered and purchased by verified agents with cards on file. If you’re building an x402 or MPP endpoint, or want Visa to help you stand one up, sign up below. We’re also opening Visa CLI to initial users in the US. DM me for an invite.
