## 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-protocol-execution-issue-5761d717 -d '<json body>'
```

Example prompt: Issue a POST protocol execution through the x402 Trust Layer with a JSON body so I can get an authorization decision and settlement summary for this transaction.

## When to prefer this

Use this endpoint when you need to issue and authorize a protocol execution action through the x402 trust layer with a verified payment settlement, particularly for compliance-sensitive, mandate-enforced, or escrow-gated actions where a trust authorization decision and audit summary are required.

## Known failure modes

- Payment not settled — 402 response returned if USDC payment is not completed
- Invalid method — only POST, PUT, PATCH are accepted as method values
- Invalid bodyType — must be one of json, form-data, or text
- Missing required fields — type, method, bodyType, or body absent returns validation error
- Unauthorized execution — allowed: false returned when trust layer denies the protocol action
- Network timeout — x402 settlement may time out under congestion

## 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 success), 'allowed' (boolean indicating whether the protocol action is authorized), and 'summary' (a human-readable string describing the outcome after x402 payment settlement).
