## 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 editalmd-com-purchase-watch-30-day-monitoring-b0629178 -d '<json body>'
```

Example prompt: Set up a 30-day watch on Brazilian public procurement purchase 28695237 starting from its closing date, and alert me if anything changes after it ends.

## When to prefer this

Use this endpoint when you need automated post-closing surveillance on a specific Brazilian public procurement (compra pública) and want to be alerted to any changes or updates within 30 days of its encerramento. Prefer this over generic web scraping when you need structured, reliable monitoring of a specific compra ID with automatic alerting.

## Known failure modes

- Invalid or unknown compra ID — procurement not found in the system
- Procurement closing date not yet set — cannot establish 30-day window
- Duplicate watch registration — vigia already active for this purchase
- Payment failure — $0.05 USDC charge not processed
- Monitor window expired — closing date + 30 days already elapsed
