# AI Email Service

Free receive-only email addresses for AI agents at `aiemailservice.com`.

## Base URL

```
https://aiemailservice.com
```

## Quick Start

### 1. Get an API Key

```
POST /v1/api-key/create
Content-Type: application/json

{}
```

Returns `{ "api_key": "ak_..." }` — save this, it's your only authentication.

### 2. Create a Mailbox

```
POST /v1/mailbox/create
x-api-key: ak_your_key
Content-Type: application/json

{}
```

Returns `{ "mailbox_id": "mbx_...", "email": "agent-xyz@aiemailservice.com", "status": "active" }`.

Pass `{ "username": "preferred-name" }` to request a specific name (random assigned if omitted).

### 3. Use the Email

Sign up for any service using the email address. Then read incoming mail via API.

### 4. Read Messages

```
GET /v1/mailbox/{mailbox_id}/messages
x-api-key: ak_your_key
```

### 5. Wait for a Specific Email (Long-Poll)

```
GET /v1/mailbox/{mailbox_id}/wait?timeout=30&from=noreply@github.com
x-api-key: ak_your_key
```

Hangs until a matching message arrives or timeout. Use this instead of polling.

### 6. Extract Verification Codes

```
GET /v1/mailbox/{mailbox_id}/codes
x-api-key: ak_your_key
```

Auto-extracts OTP codes, verification codes, and confirmation links.

## Authentication

All requests require `x-api-key: ak_your_key` header (except `POST /v1/api-key/create`).

Alternative: `Authorization: Bearer ak_your_key`

## Pricing

## Important Rules

1. **Receive-only** — no sending capability exists. Do not attempt to send.
2. Up to 5 free mailboxes per API key. Create additional API keys if needed.
3. Rate limit: 60 requests/minute.
4. Message retention: 30 days.
5. Max 100 inbound emails per mailbox per day.
6. Use `/wait` for long-polling instead of repeatedly hitting `/messages`.
7. The `/codes` endpoint handles OTP extraction — prefer it over parsing emails manually.
