## 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 palmyr-email-inbox-threads-d9567a7d
```

Example prompt: Create a new email thread in my Palmyr inbox inbox-42a8 with the subject 'Follow-up on partnership' and an opening message to hello@example.com saying 'Hi, I wanted to reconnect about our collaboration proposal.'

## When to prefer this

Use this endpoint when an AI agent needs to autonomously initiate or create email threads within a Palmyr-managed inbox, especially in agentic workflows where email communication is triggered programmatically and payments are handled via x402 USDC on Solana or Base.

## Known failure modes

- Invalid or nonexistent inbox ID returns 404
- Insufficient USDC balance or failed x402 payment returns 402
- Malformed request body returns 400
- Unauthorized access to the inbox returns 401
- Rate limiting or quota exceeded returns 429
