Same access. Different duration.

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.

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.

Crypto payment guide · Check my pass and time left

Zambo never charges you without your say. You choose when to pay.

Check my pass / time left

Optional: runs one live BTC price check and shows its receipt. This test does not save the entered key.

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.
