x402 — Keyless Machine Payments
Farebox implements x402, an open standard for HTTP micropayments. AI agents can call the API without an account — the server returns a 402 Payment Required with a USDC quote, the agent signs the payment on Solana, and retries. No invoices, no OAuth, no human in the loop.
