Zambo

Zambo is the Trust Layer for AI work. Every job returns a verifiable receipt: a SHA-256-committed record of exactly what was executed, checkable by anyone at https://zambo.dev/verify. Zambo implements AER-1, the open draft standard for AI execution receipts (IETF draft-zambo-aer1). Connect free at https://zambo.dev/mcp. No API key or signup to start; free limits vary by tool. A receipt proves the record was not changed afterward. It does not prove the answer was right. Add Zambo Receipt Bot to a Grok Bot team at https://zambo.dev/receipt-bot/ to collect and check those receipts.
