--- PipRail implements the open [x402](https://x402.org) **"402 Payment Required"** standard with **no backend, no database, no account, no API key, and no fee**. Payments settle **straight into your wallet**, verified locally against your own RPC β€” across every major EVM chain plus **Solana, TON, Tron, NEAR, Sui, Aptos, Algorand, Stellar & the XRP Ledger**. Self-custodial throughout. ## How a payment moves
How a payment moves β€” the full life of one payment, side by side. Left, the traditional MPP path (Stripe + Tempo): the agent's money is held in transit through a processor and a permissioned chain across roughly five hops, takes ~T+2 days to become spendable, and can be frozen or reversed. Right, PipRail's x402 wallet-to-wallet rail: the agent pays the merchant's wallet directly in a single on-chain transaction, the merchant gate verifies it locally, funds are spendable in seconds, there's no custodian, and the fee is 0%. **The middle is the difference.** A traditional processor holds the money in transit, takes days to release it, and can freeze or reverse it. PipRail removes the middle entirely β€” the agent pays the merchant's wallet directly, the merchant verifies it locally against their own RPC, and it settles in one transaction at **0% fee**, self-custodial end to end.  See it on piprail.com β†’

PipRail pitch deck β€” the universal payment rail for the agent economy. Click to open the full 16-slide PDF, rendered right here in your browser. ### β–ΆοΈŽ  [**Open the full deck β€” PDF**](https://github.com/piprail/piprail/blob/HEAD/PipRail-deck.pdf)  β—€οΈŽ Opens **right here in your browser** β€” no download, GitHub renders it inline. 16 slides Β· every stat sourced in the speaker notes.
The whole thesis in one read: **why** agent payments are happening now, **why** chain & token fragmentation is the enemy, and **how** a single `chain:` parameter turns PipRail into the universal adapter. The payment path is **0% forever** β€” the moat *and* the distribution; value accrues to the layer around the free rail, never the rail itself.

> ### πŸ“– Full documentation β†’ **[docs.piprail.com](https://docs.piprail.com)** > The single, searchable **source of truth** β€” every function, option, chain, and example. This README is just the front door. ## What's here | | | |---|---| | **[`@piprail/sdk`](https://www.npmjs.com/package/@piprail/sdk)** | The TypeScript SDK β€” accept & make x402 payments. The product. | | **[`@piprail/mcp`](https://www.npmjs.com/package/@piprail/mcp)** | An MCP server giving any AI agent a budget-bound wallet ([`io.github.piprail/mcp`](https://registry.modelcontextprotocol.io)). | | **[`@piprail/create`](https://www.npmjs.com/package/@piprail/create)** | `npm create @piprail` β€” scaffolds a runnable, mainnet-by-default x402 merchant in one command. Paste a public address; no key, no backend. | | **[`integrations/`](https://github.com/piprail/piprail/blob/HEAD/integrations)** | First-party agent-framework integrations β€” **OpenClaw**, **Hermes**, **elizaOS** (`@piprail/elizaos-plugin`), **n8n** (`@piprail/n8n-nodes-piprail`) & **Mastra**. Each wraps `@piprail/sdk` or `@piprail/mcp`; nothing new to build. | | **[`site/`](https://github.com/piprail/piprail/blob/HEAD/site)** Β· **[`docs/`](https://github.com/piprail/piprail/blob/HEAD/docs)** Β· **[`examples/`](https://github.com/piprail/piprail/blob/HEAD/examples)** | [piprail.com](https://piprail.com) Β· the [docs.piprail.com](https://docs.piprail.com) source Β· runnable demos. | ## Quick taste ```bash npm install @piprail/sdk viem ``` ```ts import { requirePayment } from '@piprail/sdk' app.get('/report', requirePayment({ chain: 'base', token: 'USDC', amount: '0.05', payTo: '0xYourWallet…' }), (_req, res) => res.json({ report: 'TOP SECRET' }), ) ``` That route now costs **0.05 USDC on Base**, paid straight to your wallet. Point an agent at it and it pays itself β€” name any chain with a single `chain:` parameter.
