## 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 vealth-verify-claim-cdp-settled-d2f0c6df -d '<json body>'
```

Example prompt: Can you verify that 'acme-corp.com' meets the ISO 14001 environmental management standard and give me a signed, re-checkable certificate for it?

## When to prefer this

Use this endpoint when you need a cryptographically signed, re-verifiable certificate proving a target meets a specific machine-checkable standard — particularly when the proof needs to be shared, audited, or independently verified later. Prefer this over generic verification tools when you need Vealth's unique key signature as the chain of trust, or when integrating with CDP-settled micropayment workflows via x402.

## Known failure modes

- Target is ambiguous or not resolvable — returns an error indicating the target cannot be evaluated
- Standard is not registered or not machine-checkable — returns a deferral to human review instead of a certificate
- Physical claim submitted — endpoint returns a human-review deferral, no certificate issued
- Payment not settled via CDP/x402 — request rejected with 402 Payment Required
- Invalid input schema — 400 Bad Request with field validation errors
- Vealth signing service unavailable — 503 or timeout error

## How this service works

Verify Claim (CDP-settled mirror) — check a target against one machine-checkable standard and get a signed, re-checkable certificate only our key can issue. Digital only; a physical claim defers to human review, never a fabricated pass.

## Output

A signed certificate cryptographically tied to Vealth's private key, attesting whether the target passes or fails the specified machine-checkable standard. The certificate is re-verifiable by anyone who holds Vealth's public key. Physical or subjective claims that cannot be machine-checked are deferred to human review rather than issued a fabricated pass.
