Agentcall

What This Skill Does

The AgentCall skill by kintupercy integrates the AgentCall API directly into your OpenClaw environment, enabling AI agents to interact with the real world through voice and text. It serves as a comprehensive communication bridge, allowing you to provision phone numbers, send and receive SMS, initiate automated voice calls, and even deploy autonomous AI voice agents. By leveraging the power of AgentCall, your agent can handle everything from verifying identity via OTPs to conducting complex outbound cold calls for appointment scheduling, all managed within your workflow.

Installation

To integrate this capability into your environment, run the following command in your terminal: clawhub install openclaw/skills/skills/kintupercy/agentcall Ensure you have your AGENTCALL_API_KEY set as an environment variable in your OpenClaw configuration. The skill will automatically detect this key to authenticate all requests to the base API URL (https://api.agentcall.co).

Use Cases

• Automated Verification: Use the OTP wait functionality to automate account sign-ups or security bypasses that require SMS verification.
• Appointment Scheduling: Deploy an autonomous AI voice agent to call leads or clients and manage your calendar without manual intervention.
• Customer Support: Create an automated SMS triage system that monitors an inbox and responds to common inquiries.
• Lead Qualification: Use outbound voice calls to screen potential clients based on your specific system prompts.

Example Prompts

1. "Provision a new local US phone number labeled 'SalesBot' and use it to send a welcome SMS to +15550109988."
2. "Start an AI voice call to +15550102233. Use the 'shimmer' voice, and tell them you are calling from OpenClaw to schedule a demo for this Thursday."
3. "Check the inbox for my 'SupportLine' number, extract any new OTP codes, and report the latest message content."

Tips & Limitations

• Cost Awareness: Be mindful that provisioned numbers carry monthly fees, and AI voice calls are billed by the minute ($0.20/min). Monitor your usage via the provided billing endpoints.
• Security: Since this skill handles sensitive communication, ensure your API keys are stored securely. Never hardcode credentials in your prompts.
• Rate Limiting: If you are automating high volumes, implement webhooks to react to events asynchronously rather than polling endpoints repeatedly, which can lead to inefficient performance and potential rate limiting.
