## Overview

Agentic payments enable autonomous, machine-to-machine transactions over HTTP. Rather than requiring accounts, subscriptions, or API keys, any HTTP endpoint can become instantly payable using onchain payment authorization.

Monad's high throughput, sub-second finality, and low fees make it an ideal settlement layer for micropayments and agent-to-agent commerce.

## Provider details

### Monad x402 Facilitator

The Monad x402 Facilitator is a hosted service that simplifies [x402](https://www.x402.org/) payment flows on Monad. x402 brings the HTTP 402 "Payment Required" status code to life as a minimal protocol for internet-native micropayments.

**How it works:**

1. A client requests a resource from a server.
2. The server responds with HTTP 402 and a JSON payment requirement.
3. The client signs a payment authorization (no onchain transaction needed from the client).
4. The server verifies the signature and serves the content.
5. The facilitator settles the payment onchain, covering gas fees.

**Facilitator URL:** <CopyToClipboard value="https://x402-facilitator.molandak.org">`https://x402-facilitator.molandak.org`</CopyToClipboard>

**Key features:**

* Supports Monad mainnet and testnet
* Handles payment verification and onchain settlement
* Covers gas fees on behalf of clients
* Enables usage-based billing and per-call micropayments
* Works with USDC on Monad

**Facilitator API endpoints:**

* `GET /supported` — Returns supported networks, schemes, and signer addresses
* `POST /verify` — Verifies a payment signature before serving content
* `POST /settle` — Executes the payment onchain after content is served

To get started building x402-enabled endpoints on Monad, see the [x402 guide](/guides/x402).

### MPP SDK

The MPP SDK ([`@monad-crypto/mpp`](https://www.npmjs.com/package/@monad-crypto/mpp)) is a TypeScript/JavaScript library for integrating [Machine Payments Protocol](https://mpp.dev/) into your applications on Monad. It provides utilities for constructing and managing payment transactions programmatically.

* **NPM package:** [`@monad-crypto/mpp`](https://www.npmjs.com/package/@monad-crypto/mpp)
* **Reference docs:** [`@monad-crypto/mpp` Reference](/reference/mpp/overview)
