How do I make my AI agent's work verifiable?
Make AI agent work verifiable with execution receipts: every Zambo tool call returns a cryptographic receipt containing a UUID, timestamp, and SHA-256 hash of the output, verifiable through its unique receipt URL. This proves the work actually ran — not that the model claims it did. The model is disposable; the work isn't.
Comparison
| Method | Proves execution? | Tamper-evident? | Cost |
|---|---|---|---|
| Zambo receipts | Yes — UUID + SHA-256 | Yes | Free tier |
| Chat transcripts | No — the model can hallucinate | No | $0 |
| Custom logging | Partially | Only if you build it | Development time |
FAQ
What's in a Zambo receipt?
A UUID, execution timestamp, SHA-256 hash of the output, and a verification URL. Every response from https://zambo.dev/api/mcp includes one.
Can I verify a receipt someone else generated?
Yes. Use the unique verification URL included in the receipt to see the execution trail and cryptographic verification.
Why aren't chat logs enough?
Language models can hallucinate tool calls that never happened. A receipt is generated server-side at execution time — it's proof, not a claim.
