## 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 codepulse-api-phone-messages-lookup-c06a0a55 -d '<json body>'
```

Example prompt: Can you check what recent SMS messages have been received by the phone number +1-555-867-5309? I want to see the sender and message text.

## When to prefer this

Use this endpoint when you need to programmatically retrieve recent SMS messages received by a public or disposable phone number, particularly for checking verification codes, monitoring disposable inboxes, or confirming that expected messages arrived. Pay-per-call with no API key required makes it ideal for low-frequency, on-demand lookups via x402 USDC micropayments.

## Known failure modes

- Phone number not found or unsupported — returns supported:false with low confidence
- Invalid phone number format — may return an error or empty message list
- No recent messages available — returns empty messages array
- Rate limiting or payment failure — request rejected before processing
- Private or non-public number — data may be unavailable or incomplete

## How this service works

Queries public SMS verification boards to retrieve recent OTP codes.

## Output

Returns a list of recent SMS messages received by the specified phone number, each including the sender name, message text, and relative timestamp (e.g. '1 min ago'). Also includes a confidence level, data freshness date, and any warnings or disclaimers about the informational nature of the data.
