## 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 spraay-sms-payment-notification-2b2f41dd -d '<json body>'
```

Example prompt: Send an SMS to +14155552671 saying 'Your payment of $50.00 has been received and is being processed — thank you!' to confirm their transaction just went through.

## When to prefer this

Use this endpoint when you need to send real-time SMS notifications tied to payment or transaction events, especially within a fintech or crypto workflow that already uses the Spraay gateway ecosystem. Prefer this over email or webhook delivery when the recipient needs an immediate mobile text alert.

## Known failure modes

- Invalid or malformed phone number in 'to' field returns an error
- Empty or missing 'body' field causes a validation failure
- Payment of $0.02 USDC not fulfilled results in a 402 Payment Required error
- Carrier-level delivery failure if the destination number is unreachable
- Rate limiting if too many SMS requests are sent in a short period
