## 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-agent-verify-35030401 -d '<json body>'
```

Example prompt: Check whether my agent is allowed to make a GET request using the x402 trust layer — verify the action and tell me if it's permitted and what the trust summary says.

## When to prefer this

Use this endpoint when an AI agent needs to verify whether a specific HTTP action is permitted under the x402 trust framework, particularly after a micropayment has been settled. Prefer this over generic auth checks when working within the x402 ecosystem and needing a trust-layer decision with a human-readable summary.

## Known failure modes

- Payment not settled — request blocked if x402 micropayment was not processed
- Invalid HTTP method — only GET, HEAD, DELETE are accepted; POST/PUT/PATCH will fail validation
- Missing required 'input' object — returns validation error
- Unsupported request type — only 'http' type is accepted
- Network or service unavailability returning non-200 response
- Mandate not found or expired — allowed may return false with explanatory summary

## 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 three fields: 'ok' (boolean indicating successful verification), 'allowed' (boolean indicating whether the action is permitted), and 'summary' (a plain-text explanation of the trust decision after x402 payment settlement).
