$MeteredPOST https://sovereign-x402-zeta.vercel.app/api/v1/code/execExecute Python code in a real, isolated E2B cloud sandbox. Priced at $0.02 to cover E2B's per-second sandbox runtime cost with margin -- adjust if E2B's pricing or typical execution time changes materially.
Email Send
$MeteredPOST https://sovereign-x402-zeta.vercel.app/api/v1/email/sendSend an email via Resend. The 'from' address is fixed to Resend's shared sandbox sender (onboarding@resend.dev) rather than customer- controlled, to prevent spoofing/impersonation. NOTE: until a sending domain is verified on this Resend account (resend.com/domains), the sandbox sender can only deliver to the account owner's own verified email -- any other recipient gets Resend's real 403 back, surfaced here as-is. Once a domain is verified, this same code starts working for arbitrary recipients with no changes needed.
Generate Qrcode
$MeteredPOST https://sovereign-x402-zeta.vercel.app/api/v1/qrcodeGenerate a real, scannable QR code as SVG using the `qrcode` library (pure Python, no Pillow/raster dependency needed for SVG output) -- verified against a real decoder (OpenCV's QRCodeDetector) round-trip before this replaced an earlier version that only drew the input text as a label, which was not an actual QR code.
