## Overview

OnCallClerk is an AI receptionist platform aimed at small businesses and service trades that cannot afford to miss calls. You pick an industry, choose a voice, and connect a local or toll-free number (or forward an existing line); a setup wizard fills in pricing and answers so an agent can be live in about an afternoon. The agent answers instantly with a natural voice, captures caller details, books straight into a calendar, and triggers instant alerts for urgent calls.

The product is tuned per vertical: plumbing, HVAC, real estate, property management, salons, legal, auto repair and more get their own vocabulary and urgency rules. Callers get consistent answers and your team gets real-time transcripts and structured summaries instead of voicemail. It advertises English and Spanish handling out of the box.

Beyond the dashboard, OnCallClerk exposes everything over a REST API plus a TypeScript SDK, and offers white-label reselling so agencies can run client numbers under their own brand. Plans start at $29/month with a 14-day free trial and pay-per-answered-call billing; no setup fees or contracts are advertised.

## Pricing & Plans

Free 14-day trial, then paid monthly or yearly plans starting around $29/month. Billing is usage-based on answered calls; no setup fees or contracts are advertised. Yearly plans include two months free.

## Key Features & Capabilities

- **24/7 AI call answering:** Agents answer inbound calls instantly at any hour, hold natural conversations, and capture the details that matter for each caller.
- **Industry-tuned scripts:** 18 supported industries (plumbing, HVAC, real estate, property management, salons, legal and more) come with pre-filled pricing, vocabulary, and urgency rules.
- **Appointment booking and alerts:** Agents book appointments directly into your calendar, send real-time transcripts and summaries, and flag urgent calls for immediate follow-up.
- **Developer API and SDK:** A REST API and TypeScript SDK let you create agents, provision numbers, fetch transcripts, and subscribe to call events to embed voice agents in your own product.
- **White-label for agencies:** Resell OnCallClerk under your own brand, manage multiple client numbers from one dashboard, and keep the margin between your price and the platform cost.

## Primary Use Cases

- **Never miss an after-hours emergency (Home services business owner):** A plumbing or HVAC company routes urgent calls to the on-call technician and books non-urgent jobs for the next day, so high-value emergency call-outs are not lost to voicemail.
- **Respond to leads within seconds (Real estate agent):** The agent picks up instantly, qualifies a buyer's timeline and budget, and books a showing or callback while the lead is still warm.
- **Ship voice agents to clients (Agency or developer):** Use the API, SDK, and white-label options to provision AI receptionists for multiple clients and resell them under your own brand.
