## 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 claw-messenger-subscribe-plus-plan-ef61471f -d '<json body>'
```

Example prompt: Subscribe me to Claw Messenger's Plus plan so my agent can start receiving real iMessages and SMS — use the name 'my-agent' and give me the WebSocket URL and API key I need to connect.

## When to prefer this

Choose this endpoint when you need to activate or renew a Claw Messenger Plus subscription to receive real iMessage, RCS, and SMS messages in an AI agent or backend service without owning a Mac. It is the entry point that provisions your WebSocket channel and API key, and should be called before attempting to listen for messages via the returned WebSocket URL.

## Known failure modes

- Invalid or missing required fields (type, method, bodyType, body) — returns 400 validation error
- Payment of $25 USDC not completed via x402 protocol — returns 402 Payment Required
- Malformed or expired API key provided — returns 401 Unauthorized
- Subscription already active and not eligible for renewal — may return conflict or unchanged state
- Service unavailable — returns 5xx error

## How this service works

Text your AI agent on iMessage. Claw Messenger delivers real iMessage, RCS, and SMS messages straight to your agent, webhook, or backend. No Mac required.

## Output

Returns a JSON object with ok status, the plan name (x402_plus), a WebSocket URL (wss://api.clawmessenger.com/ws) to stream incoming messages, an API key (cm_live_...) for authentication, a boolean indicating whether the subscription was renewed, an expiry timestamp, and the messages limit (6000) for the plan period.
