For developers
Agents pay a different way: see agent setup. Human checkout only here. Agents request the x402 challenge with GET /api/x402/day-pass, then submit payment with POST /api/x402/day-pass.
Wallet-enabled agents use a separate flow: pay with USDC on Base via x402. Paying programmatically? Read how x402 agent payments work: an agent receives an HTTP 402 challenge and settles it in USDC on Base.

How can another AI verify your pass?
Buy once. Your pass is proven by a public receipt, so it works in every AI you use. The public verification URL does not reveal your email, wallet address, or private access key.
RECEIPT_URL="https://zambo.dev/api/receipt/<pass-receipt-id>/verify"
curl -fsSL "$RECEIPT_URL" | jq '{id,grant_scope,expires_at,identity_binding,verification_status}'Pass lookup uses an authenticated private flow when ownership must be revealed. Public verification is an unauthenticated existence and integrity check.
