## 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 x402-trust-layer-insurance-attestation-4409d13d -d '<json body>'
```

Example prompt: Can you attest the insurance status of this seller on the x402 trust network — I need to confirm they're allowed before we release funds from escrow?

## When to prefer this

Use this endpoint when you need a cryptographically-backed or network-verified attestation of insurance or trust status for a participant in the x402 ecosystem — especially prior to releasing escrow, approving a mandate, or onboarding a certified seller. Prefer this over generic KYC checks when operating within the x402 micropayment trust infrastructure.

## Known failure modes

- Payment not settled — 402 response if USDC micropayment not completed before call
- Invalid method — input schema only permits GET, HEAD, or DELETE as method values; POST or PUT will be rejected
- Missing required fields — 'type' or 'method' absent causes validation error
- Attestation denied — 'allowed: false' with summary explaining why coverage check failed
- Network or chain unavailability — attestation cannot be confirmed if underlying trust chain is unreachable

## How this service works

68 paid x402 trust infrastructure APIs: guard, semantic escrow, mandate diff, certified seller network, KYM, mandates, compliance, disputes, and orchestration.

## Output

Returns a JSON object with 'ok' (boolean indicating successful attestation call), 'allowed' (boolean indicating whether the entity passes insurance/trust checks), and 'summary' (human-readable explanation of the attestation outcome).
