How this service works
Get a real phone number for your AI agent in under 10 minutes. Works with OpenClaw, Hermes Agent, and any LLM. Outbound calls, SMS, and inbound voice — one API. No telecom experience needed.
Output
Returns webhook subscription records associated with the authenticated lease token, optionally filtered to a specific owned phone number — including event types, callback URLs, and configuration details for inbound voice and SMS routing.
Example use cases
Audit active webhooks for agent number
“List all the webhook subscriptions tied to my AgentLine lease so I can see what events my AI voice agent is currently set up to receive.”
Filter webhooks for specific phone number
“Can you pull up the webhook configuration just for my AgentLine number +12025550143? I want to make sure inbound calls are routing correctly to my agent.”
Debug missing inbound call events
“My AI agent isn't getting inbound call notifications — can you fetch the webhook subscriptions for my AgentLine number to see if anything is misconfigured?”
