Pricing and billing - UniversalBench

UniversalBench has the simplest pricing model we could design. One free quota that resets monthly, and one paid price per call when you want more. No tiers to compare, no feature gates, no surprise auto renewals.

All prices on this page are in USD. Your bank or card issuer will convert at the time of charge if your account is in another currency.

Free tier

Every account gets 1,000 calls per month. The quota resets on the first of the calendar month. No credit card required to start. All capabilities are available on the free tier: code execution, bash, web search, LLM invocation, file reads, package installs, sessions, and secrets vault. You get the full product, just with a monthly call ceiling.

Pay as you go

When you need more than 1,000 calls in a month, top up your wallet.

What	Amount
Price per call	$0.008
Minimum top up	$5.00
Maximum top up per transaction	$500.00
Funds expire	Never
Subscription	None
Auto renew	None

A $5 top up buys you 625 paid calls. A $20 top up buys 2,500. The math is simple because the pricing is simple.

The 1,000 free monthly calls are used first. Wallet balance is only consumed after the free quota is exhausted. Your wallet does not expire and is not automatically topped up.

How a call is counted

One tool invocation is one call, regardless of how many input fields are set.

One code execution is one call
One web_search is one call
One invoke_llm is one call regardless of the underlying model
A secrets_vault operation (save, list, get, delete) is one call

Failed calls do not count against your quota.

Top up flow

Open your dashboard at universalbench.dev.
Click the “Billing” card or any of the $5, $10, $20, $50 quick top up buttons.
Pay with any major card via the secure checkout.
Your wallet balance updates the moment payment is confirmed.

You can top up any amount between $5 and $500 per transaction using the “Custom” field if the preset buttons do not match your needs.

The dashboard shows free calls remaining this month, current wallet balance, and a usage chart. The /billing/status endpoint returns the same data programmatically:

curl -H "Authorization: Bearer ubk_your_key_here" \
