Circle outlines per-request USDC payments for AI agents
- —Circle's x402 flow: a server returns 402 Payment Required and the client resends the request with a payment signature
- —Circle's terms do not verify an agent's identity, legitimacy, safety or performance; users bear responsibility
- —Cloudflare and Coinbase are forming the x402 Foundation to promote the open payments protocol
- —A 2026 study of 280 days of Base data warns payment counts should not be read as independent commerce volume
Why it matters: Betting on AI-agent payments in USDC could broaden stablecoin demand, but without authority and service verification the real volume of such transactions remains unclear.
