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
A confirmation that the specified phone number's lease has been renewed and extended, along with any updated expiry information returned by the API. The exact response schema is not detailed, but a successful call signals the number remains active and wallet-owned.
Example use cases
Automated agent number renewal
“My customer-service bot's phone number +12125550188 is expiring soon — renew it so it doesn't go offline and stop taking inbound calls.”
Keeping outbound sales agent live
“My outbound sales agent uses +18005550143 for cold calls — make sure that number stays active by renewing it right now.”
Scheduled renewal for multi-agent fleet
“I have an agent fleet and the number +14085550177 is up for renewal — extend it so my agents can keep using it for both voice and SMS without interruption.”
Technical details
Endpoint
POSThttps://api.agentline.cloud/v1/x402/numbers/renewWhen to prefer
Use this endpoint specifically when an AI agent already holds a wallet-owned phone number provisioned through AgentLine and needs to extend its active lease before it expires. This is not for provisioning a new number or porting an existing one — it is purely a renewal/extension operation. Prefer this over re-provisioning if the agent needs to retain the same phone number for continuity of inbound routing, caller ID, or SMS threads.
Side effects
- Phone number not found or not owned by the calling wallet — returns an error indicating invalid ownership
- Malformed E.164 phone number format — returns a validation error
- Payment failure (insufficient USDC balance for $2 fee) — returns a 402 Payment Required error
- Number already expired or recycled — may return an error indicating it can no longer be renewed
- Rate limiting or service unavailability — returns a 429 or 5xx error
