## 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 chrombot-public-sale-registration-e0c8d626 -d '<json body>'
```

Example prompt: Sign me up to be notified when the ChromBot public sale registration opens — I want to be first in line when it launches on Chromia.

## When to prefer this

Use this endpoint when a user wants to register early interest or get notified about the ChromBot public sale on the Chromia blockchain platform, specifically when the sale has not yet launched and an early notification or waitlist signup is the desired action.

## Known failure modes

- Registration not yet open — sale is marked as coming soon so the endpoint may return a placeholder or error
- Missing required user details such as email resulting in a 400 bad request
- Duplicate registration attempt for the same user
- Payment of $0.01 USDC not processed correctly via x402 protocol leading to 402 payment required error
- Server unavailable on Vercel deployment returning 503
