Machine Payments Protocol

An open standard for machine payments, co-authored by @tempo and @stripe. MPP is designed to be extensible and agnostic to any payment method.

[Machine Payments Protocol @mpp]

Mercator makes it easy for your agent to run multi-step agentic workflows by surfacing countless tools that can be paid for autonomously via MPP

Get started in seconds using MACH, a token designed for machine payments, that you can buy now with Apple Pay and give to your agent:

Mercator gives agents a new effort level.

By giving an agent a search engine to the world's paid tools it empowers a small model to punch above its weight, while being cheaper than larger models.

Sessions enable any business that needs streaming payments, like inference, compute, and data, to charge agents as they use their services.

Learn how @stripe uses MPP Sessions to accept streaming payments:

[Jen @BackseatVC]

Streaming payments are a super interesting business model now that agents can pay-per-call for tools

Stripe now supports streaming payments using @mpp Sessions, which allows agents to pay subcent transactions for a session, and then settle the final amount when finished.

Could be really useful for streamed compute, LLM interference, data analysis, and more.

@jeff_weinstein @stripe @tempo Even agents want the best price when shopping online and it's cheapest to pay on @tempo 🫡

[Machine Payments Protocol @mpp]

Agents are now shopping online and they've got money to spend.

They can even get discounts!

0 onchain fees for agents when paying with stablecoins on @stripe stores:

[Jen @BackseatVC]

Agents are much more likely than humans to make microtransactions which work especially well over stablecoins

Usually that means merchants selling tools to agents would have to manage crypto-specifics, like gas facilitation

Now, @stripe takes care of that for you with your @mpp integration. We deal with the crypto side and pay for gas, and payments just land in your Stripe balance

@atomHQ @stripe @tempo 🔥🔥

[Atom.com @atomHQ]

Earlier this year we launched Atom's MCP server so AI agents could search, appraise, and check domains on Atom. One step was still missing: paying for one.

Today that's closed. Atom is one of the first domain platforms live on @stripe and @tempo's Machine Payments Protocol. An agent gets a price, receives a 402, pays, and the domain lands in its user's account. No checkout page, no human in the loop.

Registrations and premium marketplace domains, live today.

@jazzicoop Machine Payments 🤝

[Jazzi Cooper @jazzicoop]

Agentic payments will be multi-platform and multi-rail. Our job is to make XRP and RLUSD first-class options wherever developers are building.

The latest XRPL AI Starter Kit expands support for the open standards developers are converging on: Open Wallet Standard, MPP from Tempo + Stripe, and x402, alongside new tooling to make building on XRPL even easier.

Let's meet developers where they are. https://t.co/pHwKnyljQR

[Georgios Konstantopoulos @gakonst]

we're about to release @tempo an aggregation service for routing across both tools and across other aggregators

like a search engine where you ask for outcomes instead of specific tools and it figures out what needs to be stitched together & how
