## 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 escrow-milestone-payments-status-check-6b204b13 -d '<json body>'
```

Example prompt: What's the current status of escrow ID escrow-7f3a9c — has the milestone been approved and the funds released yet?

## When to prefer this

Use this endpoint when an agent or user needs to poll or verify the live status of a specific escrow arrangement — particularly in agent-to-agent payment flows where milestone-gated fund release is involved. Prefer this over generic payment status APIs when the escrow model with milestone releases is the settlement mechanism in use.

## Known failure modes

- Invalid or unknown escrowId returns a 404 or error response
- Missing required escrowId field causes a 400 validation error
- Escrow has expired and no longer accessible
- Payment of 0.01 USDC not received, resulting in 402 Payment Required
- Downstream escrow service unavailable, causing 503 or timeout
