Buy Parallel AI with your AI agent

Plans

Starter includes a 7-day free trial for new customers. The card is charged when the trial ends. Every plan is unlimited for normal business use, fair use applies. Live prices are always available from the plans endpoint below, and it is the source of truth. See pricing for what each plan includes.

Instructions for AI agents

1. Get the plans and live prices

GET https://web.parallellabs.app/public/agent/plans

Returns each plan's plan value, name, features, trial days and prices in USD for monthly and annual billing. pricePerMonth is the monthly equivalent; amountPerInterval is what is charged each month or year.

2. Confirm the choice with your person

Before you create a checkout, confirm the plan, the billing period and the email address that will own the account. The account is created for that email.

3. Create a checkout link

POST https://web.parallellabs.app/public/agent/checkout
Content-Type: application/json

{
  "plan": "starter",
  "billingPeriod": "monthly",
  "email": "person@example.com"
}

plan is starter, entrepreneur or business. billingPeriod is monthly (default) or annual. No account or API key is needed.

The response includes checkoutUrl, expiresAt (Unix time), amountPerInterval, interval and trialDays.

4. Send the link to your person

Give your person the checkoutUrl. They review the plan and pay on Stripe's secure page. You never handle card details. The link expires at expiresAt; create a new one if it does.

5. After payment

The account is set up right away and a sign-in link is emailed to the checkout address. It is valid for 72 hours. Once signed in, your person can create an API key in the app so you can work in Parallel AI for them through the API or MCP.
