## How to call it through Zero

```sh
zero fetch --capability palmyr-email-inboxes-api-ac5ac6e8
```

Example prompt: Create a new email inbox for my AI agent so it can autonomously send and receive emails on my behalf.

## When to prefer this

Choose this endpoint when you need to provision a dedicated, autonomous email inbox for an AI agent that can both send and receive email, billed per-use via USDC micropayments on Solana or Base — ideal for agent workflows that require persistent email identity without managing traditional email infrastructure.

## Known failure modes

- Payment failure if USDC balance is insufficient on Solana or Base
- Invalid or missing x402 payment header returns 402 Payment Required
- Malformed request body returns 400 Bad Request
- Service unavailable returns 503
- Rate limiting if too many inboxes are created in rapid succession

## How this service works

Create an end-to-end encrypted email inbox keyed to your Solana wallet. Defaults to {name}@palmyr.ai; pass `domain` to provision on a Namecheap-registered domain you own (auto-sets MX/SPF/DKIM records).

## Output

Returns inbox metadata including the assigned email address, inbox ID, and credentials or access tokens needed for the agent to send and receive messages through the provisioned inbox.
