FAQ
A facilitator is a relayer of real-world and on-chain payments using AI agents. It verifies cryptographic signatures and broadcasts transactions to the blockchain via RPC call. Arkhia’s facilitators use the x402 protocol to enable AI agents to pay in fiat, multi-chain crypto and stablecoins.
Our Facilitator-as-a-Service enables your firm to securely process millions of simultaneous on-chain microtransactions with AI agents using the x402 payment protocol. We build, scale, and maintain the technical operations on our battle-tested API platform.
Deploy as many AI agentic facilitators as you need per product line or SKU, each with their own dedicated API keys for security and tracking.
x402 is a protocol implementing the HTTP 402 Payment Required status code for the AI era. It provides a standardised way for servers to send payment instructions to AI agents, specifying the cost and facilitator needed to unlock digital resources, enabling automated, machine-to-machine commerce.
AI agentic payments enable autonomous, high-frequency commerce by removing human bottlenecks. Enterprises and merchants can automate pay-walls for API access and data with millions of simultaneous microtransactions. This reduces operational friction and unlocks pay-per-use models that are otherwise nearly impossible to manage.
Stablecoins like USDC and USDT offer rapid borderless settlement. They prevent costly chargebacks and remove price volatility risks. For merchants, this means guaranteed payment and immediate access global liquidity without multi-day delays and high fees associated with traditional banking rails.

Networks must support a "separate fee payer" which Solana does natively, for example. In the case of EVM networks, this functionality is added with EIP-3009 for instant integration.
