• Buy the England snapshot or the AI safety toolkit via x402

  buy_file_x402

  Paid 295 USDC (school-signals-england-snapshot) or 149 USDC (dfe-ai-safety-toolkit) via x402; returns a signed 48-hour download link, the file SHA-256 and an order URL. Without payment returns the x402 terms. If your client caps automatic payments, use create_transfer_order instead.
