## 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-pipeline-execute-b1966e5d -d '<json body>'
```

Example prompt: Run a GET request through the x402 Trust Layer pipeline to check whether this operation is authorized and give me the trust summary after settlement.

## When to prefer this

Choose this endpoint when you need to route an HTTP request through a paid x402 trust layer that enforces compliance, mandate checks, and semantic escrow before authorizing access — especially when the operation involves certified seller networks, KYM (Know Your Mandate), or dispute-aware orchestration tied to on-chain settlement.

## Known failure modes

- Payment not settled — request blocked, allowed returns false
- Invalid HTTP method supplied (only GET, HEAD, DELETE accepted) — schema validation error
- Pipeline type not 'http' — rejected by const constraint
- Missing required 'input' object — 400 bad request
- x402 facilitator unavailable — timeout or 5xx error
- Insufficient USDC balance — payment failure, request not processed

## 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

A JSON object with an 'ok' boolean indicating request success, an 'allowed' boolean indicating whether the action is authorized post-payment, and a 'summary' string describing the trust layer's decision after x402 USDC settlement.
