# Plans and top-ups

Fund workspace research and understand payment confirmation and shared balances.

## Start with an account

Google and email registration share the sign-in page. Your personal workspace starts with zero credits. Browsing documentation, discovering tools and supported dry-run estimates do not purchase research.

- [View configured credit packs](/pricing)

## Buy workspace credits

Choose your workspace before opening Billing. Available packs depend on this deployment’s payment configuration; Pricing and Billing show the offers that can actually be purchased.

Complete the hosted checkout. Credits are granted after a verified payment event, not simply because a browser returns from checkout. If confirmation is delayed, inspect Billing and your balance before purchasing again.

## Track spend and access

Members share a workspace balance. Provider calls can temporarily reserve credits, and settled execution appears in Usage. An assistant spends from the workspace you approved; an API key uses the workspace where it was created.

Keep a request ID when reporting unexpected charges. Do not share payment details or secret keys in feedback.
