Open API & AI Assistant

Run your booking business by talking to it.

Every part of ActBook — availability, packages, bookings, contracts, invoices, deposits, clients, texts — is available over one open REST API. Point an AI assistant at it and it stops answering questions and starts doing the work.

“Anyone want us for a fair the third weekend of June?”

You’re open Sat Jun 20. Sunday you’re booked in Toledo — too far to add a Detroit gig that day. Hold the 20th?

“Hold it. Send the school our Circus Day package with a 25% deposit link.”

Done — date held, quote sent with the contract attached and a $625 deposit link. I’ll text you the moment they pay.

What the assistant can do

Check & hold availability

Including travel time and your service radius — it won’t offer a slot you can’t reach.

Quote & book

Price a package, create the booking, add single or multiple dates, and capture the client’s details.

Run the schedule

Edit each event date — venue, times, setup, headcount — and set availability rules: hours, buffers, daily cap, booking window.

Contracts

Send a contract for online signing, or email it as a PDF, and mark it sent or returned — from your own template.

Invoices & payments

Invoice from the booking, record payments, and text or email the client a secure link to pay a deposit or their balance — into your own Stripe account.

Text clients

Send a message, and read replies — the whole conversation, over the API.

Clients & contacts

Create, edit and merge duplicate clients, and answer inquiries — every action logged to the client’s history.

Refer & claim gigs

Pass a gig you can’t take to the ActBook network, or claim one another performer let go.

Read the numbers

Revenue, repeat rate, conversion, appearances by act — any report over any date range.

Configure the business

Company info, booking rules, packages, prices, currency, language, defaults — all settable.

Built for automation and agents
