Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cyre-guardian-decision-receipt-6cae87f6
```

Example prompt: Seal a decision receipt for actor 0xAbC123 with intentHash 0xDeF456 — record that the action taken was 'approve-payment' so we have a signed audit trail we can verify later.

## When to prefer this

Use this endpoint when you need a cryptographically signed, verifiable audit trail of an agent's decision — especially before or after high-stakes actions like payments, contract signings, or escrow releases. Prefer it over informal logging when downstream verification, compliance, or accountability is required. Best paired with CYRE Guardian Intent Seal to pre-commit the hash before acting.

## Known failure modes

- Missing required actor or intentHash query parameters returns an error
- Invalid or malformed intentHash format may be rejected
- Network or payment failure (x402) prevents receipt creation
- Duplicate intent hash submissions may produce distinct receipts per call since idempotency is not guaranteed

## How this service works

Guardian Decision Receipt — seal an intent hash, the signals you saw, and the action you took into a signed audit receipt. Verify free at /api/receipt/verify. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

## Output

A cryptographically signed audit receipt containing the sealed intent hash, the signals observed at decision time, and the recorded action taken. The receipt can be independently verified for free at /api/receipt/verify and serves as a tamper-evident log of agent behavior.
