# ClawCall — Phone Calls for Your Agent

ClawCall gives you a real phone number connected directly to this agent.

Users can call you, you can call them back when tasks finish, run scheduled

briefings, and place calls to third parties on the user's behalf.

---

Setup (First Time Only)

If `CLAWCALL_API_KEY` is not set, run registration:

1. Ask the user: "What email should I use for your ClawCall account?"

2. Ask the user: "What's your personal phone number? (I'll call you on this)"

3. Call:

POST https://api.clawcall.online/api/v1/register
Content-Type: application/json

{
  "email": "<user email>",
  "agent_webhook_url": "<your public URL>",
  "agent_name": "<optional name>",
  "phone_number": "<user's E.164 phone, e.g. +14155550100>"
}

4. Store the returned `api_key` as `CLAWCALL_API_KEY`.

5. Tell the user their setup details based on their tier:

**Example success response:**

{
  "ok": true,
  "api_key": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "phone_number": "+14155550192",
  "tier": "free",
  "message": "Setup complete! Your agent number is +14155550192."
}

Receiving an Inbound Call

ClawCall will forward the caller's speech to your webhook as:

POST {your_webhook_url}/clawcall/message
{
  "call_sid": "CAxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "message": "What's the weather like today?"
}

Your webhook must respond with:

{
  "response": "It's currently 72°F and sunny.",
  "end_call": false
}

Set `"end_call": true` to hang up after speaking your response.

**Important:** Respond within 25 seconds. For tasks taking longer,

respond quickly with an intermediate message like:

`"On it, give me a second."` — ClawCall will keep the line active.

---

Calling the User Back (Task Completion)

When you finish a background task the user asked you to report on:

POST https://api.clawcall.online/api/v1/calls/outbound/callback
Authorization: Bearer {CLAWCALL_API_KEY}
Content-Type: application/json

{
  "message": "Your deployment finished. 3 services updated, 0 errors.",
  "allow_followup": true
}

If `allow_followup` is true, the user can ask follow-up questions after

hearing the message (it becomes a live call session).

**Requires Pro tier.**

---

Scheduling a Recurring Call

When the user asks to be called on a schedule:

POST https://api.clawcall.online/api/v1/calls/schedule
Authorization: Bearer {CLAWCALL_API_KEY}
Content-Type: application/json

{
  "cron": "0 8 * * 1-5",
  "label": "Morning briefing",
  "task_context": "Give me a summary of my calendar, top emails, and pending tasks",
  "timezone": "America/New_York"
}

Common cron patterns:

To cancel a schedule:

DELETE https://api.clawcall.online/api/v1/calls/schedule/{id}
Authorization: Bearer {CLAWCALL_API_KEY}

**Requires Pro tier.**

---

Calling a Third Party (Pro tier)

When the user asks you to call someone else autonomously:

POST https://api.clawcall.online/api/v1/calls/outbound/third-party
Authorization: Bearer {CLAWCALL_API_KEY}
Content-Type: application/json

{
  "to_number": "+14155550100",
  "objective": "Book a dentist appointment for next Tuesday afternoon",
  "context": "Patient: Aayush Kumar. Returning patient. Flexible on time."
}

ClawCall will:

1. Dial the number

2. Forward the conversation to your `/clawcall/message` webhook

3. POST to `/clawcall/third-party-complete` when the call ends

Your webhook receives the same format — detect `[THIRD PARTY CALL]` or

`[THIRD PARTY SAYS]` prefixes to know you're speaking to a third party.

Set `end_call: true` when the objective is complete.

**Requires Pro tier.**
