## 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 settle-check-trust-api-demand-pack-0d1728b3
```

Example prompt: Can you pull the trust demand-pack for this x402 endpoint and tell me its verdict tier and whether there's settlement evidence on Base before I pay anything?

## When to prefer this

Choose this endpoint when you need to vet an x402 pay-per-call API before sending USDC payment — particularly when you need live probe data, on-chain settlement evidence from Base/Mogami, and tiered trust verdicts in a single response. Prefer it over generic API health checks when the target API uses the x402 protocol and USDC micropayments.

## Known failure modes

- No matching endpoints found — returns empty endpoints array
- Invalid or malformed properties parameter — likely returns 400 or empty pack
- Endpoint temporarily unreachable — live probe may return degraded or stale verdict
- Payment not processed (x402 402 response) — call blocked until $0.05 USDC payment is made
- Mogami settlement data unavailable — verdict tier may be incomplete or unverifiable

## How this service works

Trust layer for x402 endpoints: live probe, settlement evidence, verdict tiers. USDC on Base, Mogami-settled.

## Output

A JSON demand-pack (version demand-pack-v1) containing a list of x402 endpoints with their associated trust verdicts, live probe status, and settlement evidence records on Base/USDC via Mogami.
