Why an x402 Facilitator

  • One integration for Agents and merchants

    APG translates HTTP 402 requirements into a consistent authorization, verification, and settlement flow.

  • Policy enforcement before money moves

    The Facilitator checks signer, recipient, amount, asset, nonce, validity window, balance, and transaction simulation before settlement.

  • Gas-sponsored, auditable settlement

    APG submits the authorized USDC transfer, pays network gas, and returns an onchain transaction reference to the Agent.
