## 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 forgemesh-brief-subscription-20258ce8
```

Example prompt: Sign me up for the ForgeMesh Brief so I get alerted whenever something materially changes in the x402 ecosystem — catalog purges, silently changed discovery APIs, or undocumented limits that delist sellers.

## When to prefer this

Choose this endpoint when an agent operator wants proactive, event-triggered intelligence about x402 ecosystem changes rather than polling for updates manually. Ideal for operators who need to react quickly to catalog purges, discovery API changes, or newly discovered seller delisting conditions without continuously querying the x402 ecosystem themselves.

## Known failure modes

- Invalid or malformed email address returns an error
- Duplicate subscription attempt for already-enrolled email may return conflict or no-op
- Payment of $0.001 USDC not processed results in 402 Payment Required
- Missing required query parameters returns a validation error
- Downstream email delivery failure may result in no confirmation being received
