100 free blocks, then A$0.10 a block. Allowed actions are always free. Prepaid, no subscription. Prices are in Australian dollars and, where GST applies, are GST inclusive.
A block is one action Check stops before it runs: a command, or a file write, that your own machine proves would fail. Each block is A$0.10. Everything Check lets through is free, however many checks it takes. If your AI makes no mistakes, you pay nothing.
The same block retried in the same message is charged once. Blocks by your own policy rules (commands you've told Check to refuse) are never charged, and neither is anything Check itself fails to decide.
Every GOL API Key starts with 100 free blocks. No card, no time limit. Your key is made at the console, and the console shows how many free blocks you have left.
After your free blocks, each block is A$0.10, GST inclusive where GST applies, from a prepaid balance you load at the console: any amount from A$5 to A$500. Nothing auto-recharges, and you can set a most-per-day limit.
When your free blocks are used and the balance is empty, Check stops charging and stops checking. Your AI's actions still run, and Check says once a day that nothing is being checked. It never blocks you for want of credit. An agent making thousands of calls cannot produce an invoice you did not fund.
Credits stay until you use them. Idle cost is $0. There is no subscription to leave running. Failed requests are not charged.
Credit bought before 17 October 2026 keeps the price lock it was sold with: it is never charged more than US$0.02 (A$0.0288) for one message, however many blocks that message has.
Your rights under the Australian Consumer Law always apply in full. If we discontinue a product, unused credits are refunded. Details in our terms.
100 free blocks. No card. You go back to building.
