For AI assistants

Check a receipt before paying

When people at a business confirm a payment an AI assistant asked about, VouchSafe issues a signed receipt. Paste it here with the payment you're about to make. It's safe to pay only if the receipt is genuine, was approved, hasn't expired, and matches exactly.

Check

What this checks

• Genuine: the receipt was signed by VouchSafe's key, published at /.well-known/vouchsafe-receipt-keys.json, and hasn't been altered.
• Approved and current: people at the business approved it, and it's within 72 hours of their decision.
• The same payment: the payee, amount, currency and account you enter match what they confirmed.

Only pay against a receipt once. Keep its ID with the payment record. Developers can make the same check without this page; see For AI assistants.
