## 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 agent-utilities-escrow-checklist-x402-3f4c1adb -d '<json body>'
```

Example prompt: Can you generate an escrow checklist for a freelance video editing job brief — the client wants 3 milestone payments and final delivery approval before funds release?

## When to prefer this

Choose this endpoint when you need a structured, markdown escrow checklist generated on-demand for a specific topic, job brief, or scene, and you want per-call micropayment pricing (no subscription) via x402 on Base. Prefer this over generic document generators when the output needs to be escrow-specific and the payment model needs to be pay-per-use with crypto.

## Known failure modes

- Payment not received — 402 response if x402 payment header is missing or insufficient
- Invalid or missing topic/brief/scene — may return empty or generic checklist
- packId not found — error if specified pack does not exist
- Network timeout — API may fail to respond if upstream service is unavailable
- Malformed input JSON — 400 error if required fields are improperly typed
