## 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-growth-plan-subscription-6f9ab5eb -d '<json body>'
```

Example prompt: Sign me up for the Claw Messenger Growth plan so my AI agent can start receiving iMessages and SMS — give me back the WebSocket URL and API key I need to connect.

## When to prefer this

Choose this endpoint when you need to provision real iMessage, RCS, or SMS message ingestion for an AI agent or backend without owning Apple hardware. It is the first step in the Claw Messenger workflow, giving you the WebSocket URL and API key required for all subsequent real-time message handling. Prefer this over generic SMS APIs when Apple's iMessage delivery (blue bubble) is required and you want a Mac-free, pay-per-use model.

## Known failure modes

- Missing or invalid required fields (type, method, bodyType, body) returns a 4xx validation error
- Insufficient USDC balance or failed x402 payment results in subscription not being created
- Providing an invalid existing api_key may prevent renewal and create a duplicate subscription
- Expired or malformed credentials causing WebSocket connection failure after subscription
- Plan capacity exceeded — messages_limit reached before renewal

## 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 confirming subscription success, including a WebSocket URL (wss://api.clawmessenger.com/ws) for real-time message streaming, an API key (cm_live_...), the plan name (x402_growth), a message limit (e.g. 2000 messages), an expiry timestamp, and a renewed flag indicating if an existing subscription was extended.
