AgentLine gives an AI agent a real phone number. It provisions US and Canadian numbers and handles outbound calls, SMS and inbound voice conversations through a single API, so a developer can add a telephony channel to an agent without learning telecom concepts, negotiating a carrier relationship or building a media pipeline. Four integration paths are offered to suit different workflows: a Python SDK, a Node.js SDK, an MCP server, and — the most distinctive — a single prompt, where you point a coding agent at the vendor's published skill.md file and instruct it to buy a number and place a call, which the agent then carries out itself. That last path is a genuine reflection of how agent tooling is now adopted, and the vendor explicitly documents it for Claude Code, Cursor, Hermes and OpenClaw. A live demo number is published on the site so you can call and speak to an agent hosted on the platform before signing up. Pricing is pure pay-as-you-go with no monthly platform fee, which suits experiments and low-volume production alike. The Python SDK is a two-line install-and-create flow: instantiate a client with an API key, create an agent with a system prompt, buy a number and dial.
