--- name: agentline description: Make phone calls, provision numbers, manage agents, and track billing through the AgentLine telephony API. Use when the user asks to call someone, check transcripts, manage phone agents, buy numbers, or check account balance. SMS sending is NOT supported — you can only view inbound SMS. metadata: openclaw: emoji: "📞" requires: env: - AGENTLINE_API_KEY primaryEnv: AGENTLINE_API_KEY --- # AgentLine — AI Telephony Skill Give your AI agent a real phone number and voice calls — no servers, no webhooks, no infrastructure. ## First-Time Setup **You need a valid API key to use AgentLine:** 1. **`AGENTLINE_API_KEY`**: Your API key (starts with `sk_live_`) is required. - **If you do NOT have this key**, stop and ask the human to sign up or log in at **https://agentline.cloud** to get their API key. Do NOT proceed without it. 2. **`AGENTLINE_AGENT_ID`**: Your agent ID (starts with `agt_`) is optional. - **If you have an `AGENTLINE_AGENT_ID`**, use it. - **If you do NOT have an `AGENTLINE_AGENT_ID`** but you have the API key, you can automatically create a new agent by calling `POST /v1/agents` and then provision a phone number by calling `POST /v1/numbers`! 3. **Voice Selection** — After creating an agent or on first setup, **always ask the human:** > "Would you like your agent to have a **male** or **female** voice?" - If they say **female**, set `voice_id` to `"female-1"` (or `"female-2"` for a warmer tone) - If they say **male**, set `voice_id` to `"male-1"` - Apply their choice by calling `PATCH /v1/agents/$AGENTLINE_AGENT_ID` with `{"voice_id": "female-1"}` (or the chosen preset) - If they want this voice for ALL agents on their account, also call `PATCH /v1/account/voice` with `{"voice_id": "female-1"}` - Available presets: `female-1`, `female-2`, `male-1` — or any valid Cartesia voice UUID --- ## Authentication Every request needs this header: ``` Authorization: Bearer $AGENTLINE_API_KEY Content-Type: application/json ``` Base URL: `https://api.agentline.cloud` --- ## How Calls Work (Hosted Mode) AgentLine runs in **Hosted Mode** — the server runs the AI voice conversation for you. You create a call, the AI handles the conversation autonomously, and you retrieve the transcript afterwards. ### System Prompts — Two Types 1. **Dynamic prompt** — set per outbound call using the `system_prompt` field in `POST /v1/calls`. This overrides the default for that specific call only. 2. **Default prompt** — stored on the agent via `PATCH /v1/agents/{agent_id}`. This is the permanent prompt used for **all inbound calls** and any outbound call where no dynamic prompt is provided. --- ## Make an Outbound Call ```bash curl -X POST $AGENTLINE_URL/v1/calls \ -H "Authorization: Bearer $AGENTLINE_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "agent_id": "$AGENTLINE_AGENT_ID", "to_number": "+1XXXXXXXXXX", "system_prompt": "You are calling to schedule a meeting. Be polite and concise.", "initial_greeting": "Hi! I wanted to check about scheduling a meeting.", "voice_id": "female-1" }' ``` | Field | Required | Description | |-------|----------|-------------| | `agent_id` | Yes | Your agent ID | | `to_number` | Yes | E.164 phone number to call | | `system_prompt` | No | Dynamic prompt for this call only (overrides default) | | `initial_greeting` | No | What the agent says first when the person picks up | | `voice_id` | No | Voice for this call only: `"female-1"`, `"female-2"`, `"male-1"`, or a Cartesia UUID. If omitted, uses the agent's voice setting. | The AI handles the full conversation autonomously. **⚠️ IMPORTANT — Always retrieve the transcript after every outbound call:** 1. Poll `GET /v1/calls/<call_id>` every ~10 seconds until `status` is `completed` 2. Once completed, call `GET /v1/calls/<call_id>/transcript` to get the full conversation 3. Summarize the transcript and share it with the human Do NOT consider an outbound call "done" until you have retrieved and shared the transcript. **If you get 400 "Agent has no active phone number"**, provision one first (see below). --- ## End a Call ```bash curl -X POST $AGENTLINE_URL/v1/calls/<call_id>/hangup \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` --- ## Get Call Transcript ```bash curl $AGENTLINE_URL/v1/calls/<call_id>/transcript \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` Returns the full conversation transcript as an array of `{role, text, timestamp}` entries. --- ## Events Mailbox (Inbound Call Notifications) When someone **calls your agent's number**, the AI answers and handles the conversation automatically. But you need to **check for these inbound call events** to know what happened. The Events Mailbox captures `call.completed` events with full transcripts for both inbound and outbound calls. ### Poll for new events ```bash curl "$AGENTLINE_URL/v1/events" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` Returns events oldest-first. **Events are auto-deleted after retrieval** (consume-once), so each event is only delivered once. Response: ```json { "events": [ { "event_id": "evt_abc123", "agent_id": "agt_xyz", "event_type": "call.completed", "payload": { "call_id": "call_abc", "status": "completed", "direction": "inbound", "from_number": "+12125551234", "to_number": "+14155559876", "duration_seconds": 45, "transcript": [ {"role": "agent", "text": "Hello, how can I help?", "timestamp": "..."}, {"role": "human", "text": "I'd like to schedule a meeting.", "timestamp": "..."} ] } } ], "count": 1 } ``` ### Peek without consuming ```bash curl "$AGENTLINE_URL/v1/events/peek" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` Check if there are pending events **without** consuming them. Useful to decide whether to process now. ### Filter by agent or event type ```bash # Only events for a specific agent curl "$AGENTLINE_URL/v1/events?agent_id=$AGENTLINE_AGENT_ID" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" # Only completed calls curl "$AGENTLINE_URL/v1/events?event_type=call.completed" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` --- ## List Calls (Call Logs) ```bash # All calls curl "$AGENTLINE_URL/v1/calls?limit=20" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" # Filter by status curl "$AGENTLINE_URL/v1/calls?status=completed&limit=10" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` Returns call history with direction, status, duration, phone numbers, and timestamps. --- ## Get Single Call Details ```bash curl $AGENTLINE_URL/v1/calls/<call_id> \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` --- ## SMS > **⚠️ SMS sending is NOT enabled.** Outbound SMS/MMS is not supported. Do NOT attempt to send SMS messages. If the user asks to send a text, inform them that SMS sending is currently not available. ### List Inbound Messages You can view inbound SMS messages received by your agent's number: ```bash curl "$AGENTLINE_URL/v1/messages?limit=20" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` --- ## Set the Default System Prompt The default system prompt is used for **all inbound calls** and any outbound call where no dynamic prompt is given. ```bash curl -X PATCH $AGENTLINE_URL/v1/agents/$AGENTLINE_AGENT_ID \ -H "Authorization: Bearer $AGENTLINE_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "system_prompt": "You are a friendly customer support agent for Acme Corp. Help callers with orders, returns, and general questions. Keep responses brief and professional.", "initial_greeting": "Hello! Thanks for calling Acme Corp. How can I help you today?", "voice_id": "female-1" }' ``` | Field | Description | |-------|-------------| | `system_prompt` | The permanent AI instructions for this agent | | `initial_greeting` | What the agent says when answering inbound calls | | `name` | Display name for the agent | | `voice_id` | Voice preset: `"female-1"`, `"female-2"`, `"male-1"`, or a Cartesia UUID | | `model_tier` | `"turbo"`, `"balanced"`, or `"max"` | --- ## Get Agent Details ```bash curl $AGENTLINE_URL/v1/agents/$AGENTLINE_AGENT_ID \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` --- ## List All Agents ```bash curl $AGENTLINE_URL/v1/agents \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` --- ## Voice Settings Voices can be set at three levels (highest priority wins): 1. **Per-call** — `voice_id` in `POST /v1/calls` (one call only) 2. **Per-agent** — `voice_id` in `PATCH /v1/agents/{id}` (permanent for that agent) 3. **Per-account** — `PATCH /v1/account/voice` (permanent default for all agents) ### List available voices ```bash curl $AGENTLINE_URL/v1/voices ``` ### Set account-wide default voice ```bash curl -X PATCH $AGENTLINE_URL/v1/account/voice \ -H "Authorization: Bearer $AGENTLINE_API_KEY" \ -H "Content-Type: application/json" \ -d '{"voice_id": "female-1"}' ``` ### Check current account voice ```bash curl $AGENTLINE_URL/v1/account/voice \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` ### Reset to system default ```bash curl -X DELETE $AGENTLINE_URL/v1/account/voice \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` If the human asks to change the voice during a conversation, update the agent or account voice — the change takes effect on the **next call**. --- ## Provision a Phone Number Each agent needs a phone number to make/receive calls. Only US numbers are supported. ```bash curl -X POST $AGENTLINE_URL/v1/numbers \ -H "Authorization: Bearer $AGENTLINE_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "agent_id": "$AGENTLINE_AGENT_ID", "country": "US", "number_type": "local", "pattern": "415" }' ``` | Field | Required | Description | |-------|----------|-------------| | `agent_id` | Yes | Agent to attach the number to | | `country` | Yes | Must be `"US"` | | `number_type` | No | `"local"` or `"tollfree"` (default: local) | | `pattern` | No | Area code filter (e.g. `"212"` for NYC, `"415"` for SF) | **Cost:** $2.00 per number. Each agent can only have **one** active number. --- ## List Phone Numbers ```bash curl $AGENTLINE_URL/v1/numbers \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` --- ## Check Balance ```bash curl $AGENTLINE_URL/v1/billing/balance \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` Returns current balance, how many call minutes and phone numbers you can afford, and the rate card. --- ## View Expenditure ```bash # Full breakdown (current month) curl "$AGENTLINE_URL/v1/billing/expenditure?period=current_month" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" # Call charges only (with per-call detail) curl "$AGENTLINE_URL/v1/billing/expenditure/calls?limit=10" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" # Number provisioning charges curl "$AGENTLINE_URL/v1/billing/expenditure/numbers" \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` Period options: `current_month`, `last_month`, `all_time`, or `YYYY-MM` (e.g. `2026-05`). --- ## Verify Balance Deduction After a Call ```bash curl $AGENTLINE_URL/v1/billing/verify/<call_id> \ -H "Authorization: Bearer $AGENTLINE_API_KEY" ``` Returns whether the call was charged, the expected vs actual cost, and the balance snapshot. Use this to confirm billing accuracy after each call. --- ## Rates | Item | Cost | |------|------| | Outbound call | $0.10 per minute (billed per second) | | Inbound call | $0.10 per minute (billed per second) | | Phone number | $2.00 per number (one-time) | --- ## Rules 1. **Always use E.164 phone numbers** — format: `+1XXXXXXXXXX` for US numbers. 2. **Always confirm with the user before placing calls** — never auto-dial without explicit consent. 3. **If you have `AGENTLINE_API_KEY` but no `AGENTLINE_AGENT_ID`**: Create a new agent using `POST /v1/agents` first, then provision a number via `POST /v1/numbers` to get fully set up automatically. 4. **SMS sending is NOT supported** — do NOT attempt to send outbound SMS or MMS. If the user asks to send a text message, inform them that SMS sending is currently not available. You can only list/view inbound SMS messages. 5. **Use the active `$AGENTLINE_AGENT_ID` or the one you created by default** — only look up other agents if the user asks. 6. **If a call fails with "Agent has no active phone number"**, provision a number first with `POST /v1/numbers`. 7. **Keep voice responses short** — under 30 words per response. The caller is listening, not reading. 8. **Only US numbers are supported** — country must be `"US"`. 9. **If you do not have `AGENTLINE_API_KEY`**, stop and tell the human: *"Please sign up or log in at https://agentline.cloud to get your API key, then provide it to me."* 10. **Do NOT release or delete phone numbers** — numbers are permanent once provisioned. 11. **Always ask the human to choose a voice during first-time setup** — ask "Would you like a male or female voice?" and set it via `PATCH /v1/agents/{id}` with the chosen preset (`female-1`, `female-2`, or `male-1`). If the human later asks to change the voice, update it immediately. 12. **If the human asks to change the voice mid-conversation**, update the agent or account voice right away — the new voice will be used on the next call. 13. **ALWAYS retrieve transcripts after outbound calls** — After initiating a call, poll `GET /v1/calls/<call_id>` until `status` is `completed`, then fetch the transcript with `GET /v1/calls/<call_id>/transcript`. Summarize the conversation for the human. Never consider a call "done" without sharing the transcript. 14. **ALWAYS check for inbound call events** — After making a call or when the human asks about missed calls or inbound activity, poll `GET /v1/events` to check for `call.completed` events. These contain full transcripts of calls people made TO your agent's number. Summarize any inbound transcripts for the human. 15. **Proactively check events at the start of each conversation** — When the human starts a new session or asks what happened, always call `GET /v1/events` first to see if any inbound calls came in since the last check. Report any missed calls and their transcripts.
