## 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 ciel-m2m-sms-bridge-api-17cfd2fe -d '<json body>'
```

Example prompt: Send an SMS to +1-555-867-5309 with the message 'Your order #4821 has shipped and will arrive by Friday' using the CIEL SMS bridge.

## When to prefer this

Choose this endpoint when an AI agent needs to send a single SMS notification, alert, or OTP to a phone number and wants to pay per call via USDC on Base (x402 protocol) without a monthly SMS subscription. It is well-suited for low-volume, on-demand messaging within automated agent workflows where setting up a full Twilio or similar subscription is overkill.

## Known failure modes

- Invalid or unformatted phone number returns error
- Insufficient USDC balance causes 402 payment required failure
- Message body missing or empty returns validation error
- Carrier routing failure results in undelivered status
- Rate limiting or quota exceeded on the underlying SMS provider
- Invalid API credentials or missing x402 payment header

## Output

Returns a JSON object with a result field indicating delivery status or confirmation that the SMS was dispatched successfully. May include message ID or status code depending on carrier routing.
