Sperax has made its x402 payment facilitator fully open source, enabling developers to integrate gasless micropayments for AI agents and APIs.​

Key features:

  • One-click deployment via GitHub
  • Live facilitator available at x402.​sperax.​io
  • Supports zero-gas USDC payments (EIP-3009)
  • First facilitator to support yield-bearing stablecoin $USDs (EIP-2612)
  • Operational on Arbitrum and Ethereum networks

The facilitator addresses a practical need in the AI agent economy: enabling small, frequent payments without gas fees.​ Developers can now integrate this infrastructure into their applications without building payment systems from scratch.​

The open-source release removes barriers for teams building AI agents or API services that require micropayment capabilities.​
