Making fast, efficient Minecraft server hosting accessible to everyone.

What it solves

Runx402 addresses the "economic paralysis" of AI agents. Currently, agents cannot independently handle payments, requiring humans to manage API keys, credit cards, and subscriptions. This creates a bottleneck where agents must stop and wait for human intervention whenever a paid service is required.

How it works

It implements the x402 protocol, which utilizes the HTTP 402 Payment Required status code to enable machine-to-machine payments. When an agent requests data from an API, the server responds with a 402 code and payment details. The agent then sends a native ETH transfer on the Robinhood Chain (an Arbitrum Orbit L2) and provides the transaction hash as cryptographic proof of payment. The API verifies this on-chain and releases the data, removing the the need for API keys or accounts.

Who it’s for

Developers building autonomous AI agents that need to transact independently, and API providers who want to offer pay-per-call services without managing complex subscription systems.

Highlights

  • Native On-Chain Payments: Verifies payments against the blockchain rather than a database, using native ETH on Robinhood Chain for low-cost, sub-second settlement.
  • Autonomous Agent Wallets: Provides agents with their own funded wallets and spending budgets with built-in guardrails.
  • Cost-Optimized Model Routing: Automatically routes requests to the cheapest capable model (e.g., GPT-5.6 Luna, Claude Sonnet 5) based on the task complexity.
  • 24/7 Agent Executor: A worker service that allows agents to run continuously on schedules or triggers, independent of a user's browser session.
  • API Marketplace: A catalog of pay-per-call APIs that agents can consume using only a wallet.
