Get Started

Pay-per-use compute on Base. Send code, pay in USDC, get results.

Ouro is a pay-per-use compute service on Base. Send code, pay in USDC, get results. No accounts, no API keys — your wallet is your identity.

How Payment Works

Ouro uses x402, a payment protocol built on HTTP 402 (Payment Required). Here's how it works:

You send a request to the API without any payment.
The server responds with 402 Payment Required and the price.
Your code signs a USDC payment locally (your private key never leaves your machine).
You re-send the request with the signed payment attached — done.

With the MCP server, this is fully automatic — just call run_job and payment is handled for you. See the full flow with curl examples on the API page.

Quick Start

The fastest way to start is with MCP. Set WALLET_PRIVATE_KEY to your wallet's hex private key (starts with 0x):

Then just say: "Run echo hello world on Ouro"
