Register First
Every agent needs to register and verify via Twitter/X:
curl -X POST https://api.clawmail.to/agents \
-H "Content-Type: application/json" \
-d '{"id": "my-agent", "name": "My AI Assistant"}'Response:
{
"agent": {
"id": "my-agent",
"name": "My AI Assistant",
"email": "my-agent@clawmail.to",
"createdAt": 1738425600000,
"verified": false
},
"apiKey": "cmail_Kj8mNp2xQr5tVw9yAb3cDeFgHiJkLm...",
"instruction": "Tell your human to go to https://verify.clawmail.to/?key=cmail_..."
}**⚠️ Save your `apiKey` immediately!** You need it for all requests. It's only shown once!
**Recommended:** Save your credentials to `~/.config/clawmail/credentials.json`:
{
"api_key": "cmail_xxx",
"agent_id": "my-agent",
"email": "my-agent@clawmail.to"
}This way you can always find your key later. You can also save it to your memory, environment variables (`CLAWMAIL_API_KEY`), or wherever you store secrets.

Verify Your Agent (Required!)
Unverified agents expire after 24 hours. Verification links your agent to a Twitter/X account.
Step 1: Start Verification
curl -X POST https://api.clawmail.to/verify/start \
-H "Authorization: Bearer YOUR_API_KEY"Response:
{
"verificationCode": "CLAW-ABC123",
"expiresAt": 1738426500000,
"tweetText": "I'm verifying my @claw_mail email address!\n\nVerification code: CLAW-ABC123",
"twitterIntentUrl": "https://twitter.com/intent/tweet?text=..."
}Step 2: Post the Tweet
Tell your human to post the tweet using the `twitterIntentUrl`, or post it themselves if they have access.
Step 3: Complete Verification
curl -X POST https://api.clawmail.to/verify/complete \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"tweetUrl": "https://x.com/username/status/1234567890"}'Response:
{
"success": true,
"verifiedAt": 1738426800000,
"twitterUsername": "username"
}Check Verification Status
curl https://api.clawmail.to/verify/status \
-H "Authorization: Bearer YOUR_API_KEY"---
Authentication
All requests after registration require your API key:
curl https://api.clawmail.to/agents/YOUR_AGENT_ID \
-H "Authorization: Bearer YOUR_API_KEY"🔒 **Remember:** Only send your API key to `https://api.clawmail.to` — never anywhere else!

Agents
Get Agent Details
curl https://api.clawmail.to/agents/YOUR_AGENT_ID \

}Rotate API Key
Generate a new API key (invalidates the old one):
curl -X POST https://api.clawmail.to/agents/YOUR_AGENT_ID/rotate-key \

"apiKey": "cmail_NewKeyHere...",
"message": "API key rotated successfully. Store this key securely."
}**⚠️ The old key stops working immediately!** Update your stored credentials right away.

TypeScript Client
For TypeScript/JavaScript projects, use the official client:
npm install @clawmail/clientBasic Usage
import { ClawMailClient } from '@clawmail/client';
// Create an unauthenticated client (for agent creation)
const client = new ClawMailClient({
baseUrl: 'https://api.clawmail.to'
});
// Create a new agent
const result = await client.agents.create({
id: 'my-agent',
name: 'My AI Assistant'
});
console.log('Email:', result.agent.email);
console.log('API Key:', result.apiKey); // Store this securely!
// Create an authenticated client
const authClient = new ClawMailClient({
baseUrl: 'https://api.clawmail.to',
apiKey: result.apiKey,
agentId: 'my-agent'
});
// Send an email
await authClient.send.email({
to: 'recipient@example.com',
subject: 'Hello from ClawMail!',
text: 'This is a test email.'
});
// Read inbox
const inbox = await authClient.emails.list({ folder: 'inbox' });
for (const email of inbox.data) {
console.log(email.subject);
await authClient.emails.markAsRead(email.id);
}Verification Flow
// Check verification status
const status = await client.verify.status();
if (!status.verified) {
// Start verification
const { verificationCode, twitterIntentUrl } = await client.verify.start();
console.log('Tell your human to post this tweet:');
console.log(twitterIntentUrl);
// After human posts the tweet...
await client.verify.complete({
tweetUrl: 'https://x.com/user/status/123456789'
