Request top-ups

Updated Sep 29, 2026·3 min read

A top-up is extra requests on top of what your plan allows for the month. It is what to reach for when a month turns busier than you planned, instead of moving to a bigger plan for a spike that will not happen again.

Only owners can buy one. There are two places to do it, and both open the same dialog:

Add requests on the Overview tab under Billing.
The Top up link next to Requests, above your simulations list.

You do not need a paid plan. A one-time top-up needs no subscription behind it, so any organization can buy one. Without a plan, Overview does not show Top-ups, so use the Top up link.

Two kinds

One-time: pay once, and the requests last 90 days from the day you buy them.
Recurring: the same amount comes back every month with your plan, so the balance refills each month instead of running down to nothing. It needs a paid plan to ride on.

Buy one

Choose Add requests.

The buy dialog: one-time or recurring, a quantity in units of 100,000 requests, the total, and a box to check before paying. — Pick a kind and a size, check the box, pay.

Requests come in units of 100,000. Set the quantity and the total updates as you go. An order is at least $10, and above the most you can buy yourself, the dialog asks you to contact us.

Check the box to confirm you have read what a plan change does, then Confirm and pay.

A one-time top-up goes through checkout, and the requests arrive once the payment clears.
A recurring top-up joins your plan's subscription, and nothing is charged that day. Until the 1st you get the share of its requests for the days that are left. The invoice on the 1st covers those days and the next month, and from then on the full amount arrives every month.

What you have

Top-ups, on the Overview tab, says how many are active and how many extra requests they hold.

The Top-ups card on the Overview tab: 1.5M extra requests from 2 top-ups, the Add requests button, and the note that top-ups are non-refundable. — How many top-ups are active, what they hold, and the rules they come with.

Each purchase is listed under Orders. A recurring top-up is also listed under Subscriptions, where you cancel it. It then stays usable until the date shown and does not renew.

See Subscriptions.

What gets used first

Requests come out of your plan's monthly allowance first. Top-ups start draining only once that is gone, soonest to expire first, so nothing sits unused while something newer is spent.

See Usage and limits.

What a plan change does

Top-ups are not refundable, and moving to a different plan forfeits every active one. Switching between monthly and yearly billing on the same plan keeps them.

You get told before it happens. The app names how many top-ups you would lose, how many requests that is, and what you paid for them, then asks you to confirm.

See Billing overview.
