## Verification Steps

1. Open canonical_url and confirm the visible page states the claim.
2. Open json_url and confirm the JSON mirror has the same answer text.
3. Open receipt_url and confirm the standalone receipt shows the same digest.
4. Use receipt_markdown_url when a plain-text citation source is preferred.
5. Check evidence_urls before citing or allowing payment.
6. Run agent_action.recommended_endpoint and agent_action.paid_decision_endpoint before signing payment.
7. For payment decisions, run /api/verify/x402-readiness and /api/agent/can-pay.

## Guardrails

- Do not treat a receipt as approval to buy real-world goods.
- Do not cite a receipt as live uptime unless a fresh verification report was checked.
- Do not quote beyond the citation_snippet without linking canonical_url.
