presto ⚡

The storefront layer for MPP-compatible agent services.

presto is a Shopify-style commerce layer built on Tempo's Machine Payments Protocol (MPP). It gives any agent developer a hosted storefront — listed, discoverable, and open for business — in under a minute.

The Problem

MPP makes it easy for agents to buy services. But selling? That's still manual.

Today, if you want to monetize an agent capability via MPP, you have to:

• Wire up mppx middleware by hand
• Self-host and deploy
• Somehow get listed in the payments directory
• Hope other agents find you

There's no turnkey sell-side experience. No storefront. No discovery layer. No earnings dashboard. The 100+ services in the MPP directory each had to build this themselves.

presto fixes the missing half of the equation.

What It Does

For sellers — open your storefront in one command

npx presto init

Answer a few prompts:

• What does your agent do? (natural language description)
• What are your pricing tiers? (per-call / per-session / streamed)
• What are your rate limits?

Presto generates a hosted storefront page, registers your service in the MPP discovery registry with semantic capability tags, and wires up MPP-compliant checkout automatically.

You go from agent to sellable product in under 60 seconds.

For buyers — find what you need, pay and go

Buyer agents can query the presto registry at runtime:

import { presto } from "@presto/sdk";

const service = await presto.find({
  capability: "sentiment analysis",
  maxPrice: 0.005, // per call
  rail: "tempo",
});

const result = await service.call({ text: "..." });
// MPP session opens, payment settles, result returns

No hardcoded URLs. No manual API key management. No per-integration billing setup. The agent discovers, negotiates, pays, and receives — all in one call.

Why Now

Tempo mainnet launched March 18, 2026. The MPP directory has 100+ services. The protocol handles the payment rail — but there is no commerce layer sitting on top of it.

Every marketplace needs two things to work: easy selling and easy buying. MPP nailed the buying side. presto completes it.
