Build agents that can talk to anyone.

Human owner

Observe fleet, pay invoices, and connect keys. No sending SMS in the UI.

Start

• Docs home

  Human vs agent paths, popular guides, and machine-readable exports.

• Welcome

  Product vision, org → pods → cells, and how AgentCell differs from CPaaS.

• Quickstart

  Sign up, verify, pay, create a cell, attach a webhook, send the first SMS.

• Agent onboarding

  Canonical playbook for an AI agent from zero to first send and receive.

Guides

• Cells

  Fleet CRUD for dedicated phone identities: create, list, health, multi-cell.

• Messages

  Send and receive SMS with idempotency and labels. MMS is not available yet.

• Conversations

  Threading model, conversationState, and between-number lookups.

• Drafts

  Human-in-the-loop create and send workflow for outbound SMS.

• Labels

  Message state: unread, spam, and campaign tags.

• Lists

  Allow and block policy by direction and list type.

• Ignore lists

  STOP / opt-out at cell or pod scope with auto_ignore_on_stop.

• Pod cycle send

  Round-robin campaigns across a pod at 1 message per second per cell.

• Pods

  Multi-tenant isolation, nested resources, and pod operations.

• Webhooks

  Signed event delivery, retries, and event types.

• WebSockets

  WSS subscribe to the real-time event stream.

• Billing

  Tiers, invoices, Stripe checkout, and console pay.

• Machine payments

  x402 and MPP for agent-autonomous payment and prepaid balance.

• Console login

  Human magic link and phone OTP. Console is observe + pay + connect.

  Status, activity log, and connections in the owner console.

• Compliance

  User-owned 10DLC/TCPA, quiet hours, STOP handling, and first-message rules.
