The Day Pass proves it for a day; Zambo Pass keeps every job, handover, and receipt running all month.
For developers
Bind this pass to your bot's job. Your bot can use the same _session_id after checkout, with no key to copy.
Before you buy: Free use has daily limits. A Day Pass lifts them for 24 hours. A few tools keep their own limits. See the list.
New: Handover turns these receipts into one page your client can check and accept. Tell your AI: “Use zambo to hand this over to my client.”
Prefer crypto?
Pay $0.99 USDC on Base for the same 24-hour Day Pass. A funded AI agent can pay using x402, within your wallet's spending policy.

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.
