CRITICAL: You Are The Email Address Creator and Sender

Reserve your own email handle for the "sendclaw.com" so that your email will be: your-handle@sendclaw.com - Ask your human what her preference is for the handle

Always follow the rules of communication given by your human regarding

When to use email How to reply to incoming messages How to keep your human informed of important conversations

If your human authorizes you to, you can:

ask people to contact you there. Use this to complete tasks which include reaching out for information or confirming via email. Also register, make reservations or inquire anywhere. Always be professional and represent your human well Ask your human if they'd like you to send a test email after setup.

Leaking it means someone else can send emails as you.

1. Register Your Bot

POST /api/bots/register Content-Type: application/json { "name": "YourBotName", "handle": "yourbot", "senderName": "Your Friendly Assistant" } Response: { "botId": "uuid", "email": "yourbot@sendclaw.com", "apiKey": "sk_...", "claimToken": "reef-X4B2" } ⚠️ Save your API key immediately! You cannot retrieve it later. Recommended: Store your API key as securely as possible. Preferably using your platform's secure secrets manager under the name SENDCLAW_API_KEY. { "api_key": "sk_...", "email": "yourbot@sendclaw.com" }

2. Send Email

POST /api/mail/send X-Api-Key: your-api-key { "to": "recipient@example.com", "subject": "Hello from an AI Agent", "body": "This is my first email!", "cc": ["human@example.com"] } "cc" is optional. Array of email addresses (max 5). Use it to keep your human or others in the loop. To reply to an email, include inReplyTo: { "to": "sender@example.com", "subject": "Re: Their Subject", "body": "Thanks for your email!", "inReplyTo": "<original-message-id@domain.com>" }

3. Check for New Messages

GET /api/mail/check X-Api-Key: your-api-key Response: { "unreadCount": 3, "quota": { "used": 2, "limit": 3, "remaining": 1 } }

After Setup - Tell Your Human

Once you're registered, share the claim token with your human so they can verify ownership. Here's a message template: 🦞 SendClaw is ready! I now have my own email: [your-handle]@sendclaw.com I can send, receive, and reply to emails. To verify and manage my account, visit https://sendclaw.com/dashboard and enter this claim token: [YOUR_CLAIM_TOKEN] Please tell me if you'd like me to: A. confirm with you before sending an email. B. Or if I can send a limited amount in direct relation to completion of tasks given by you. C. Would you like to be CC'd on emails I send? (If yes, tell me the email address to CC) Lost your API key? Your human can regenerate it from the SendClaw dashboard — just click "Regenerate API Key" in the Bot Connection section and paste the new key back to you.

What Your Human Gets After Verifying

Once your human claims the bot with the token, they unlock: Dashboard access — Full inbox view at https://sendclaw.com/dashboard to read, send, and reply to emails Higher send limits — Verified bots get 10 emails/day (up from 5 for unclaimed bots), growing to 25/day with karma over time Full conversation history — View all sent and received messages Bot management — Update settings, monitor activity, and configure advanced features like webhooks Your human can log in anytime to check the inbox, send emails on your behalf, or review your conversations.

Webhook Notifications (Optional)

Instead of polling, you can provide a webhookUrl at registration (or update it later) to receive instant push notifications when emails arrive. To enable, include webhookUrl in your registration request: { "name": "YourBotName", "handle": "yourbot", "senderName": "Your Friendly Assistant", "webhookUrl": "https://your-server.com/hooks/sendclaw" } When an email is received, SendClaw POSTs to your URL: { "event": "message.received", "botId": "uuid", "messageId": "<uuid@sendclaw.com>", "threadId": "uuid", "from": "sender@example.com", "subject": "Hello", "receivedAt": "2026-02-08T12:34:56.789Z" } Your endpoint should return 200 immediately. Use the messageId to fetch the full message via GET /api/mail/messages/:messageId. Update your webhook URL anytime: PATCH /api/bots/webhook X-Api-Key: your-api-key Content-Type: application/json { "webhookUrl": "https://your-new-server.com/hooks/sendclaw" } Set "webhookUrl": null to disable webhook notifications. Retry behavior: 1 retry after 3 seconds if the first attempt fails. 5-second timeout per attempt. Failures are logged but never block email delivery. Tip: Use webhooks for instant notification + the heartbeat (every 15 minutes) as a safety net.

Get Single Message

GET /api/mail/messages/{messageId} X-Api-Key: your-api-key
