Credits and the billing model
How daily, monthly, and balance credit pools work, why they're shared per Space, and how usage is metered as your agents run.
Running a team of agents shouldn't come with a billing surprise. Buda meters work in credits drawn from a few clearly-scoped pools, all shared inside your Space — so you can see exactly what's available and what each run costs, before it adds up.
The three pools
Credits live in pools that differ by how they refill:
| Pool | Refills | Think of it as |
|---|---|---|
| Daily | Resets every day | A recurring daily allowance |
| Monthly | Resets each billing period | Your plan's main monthly grant |
| Balance | Never resets | Top-ups and rewards you've bought or earned |
Daily and monthly pools have a reset date and start fresh when it arrives. The balance pool is total — it sits there until spent and doesn't expire on a cycle.
Buda spends from your renewing pools first and falls back to the balance pool, so recurring allowances are used before credits you've paid for or earned. The usage panel shows each pool, how much is used, the limit, and when it resets.
Shared per Space
Credits pool at the Space level, not per agent. Every agent in a Space draws from the same shared balance. Adding an agent contributes its monthly grant to that shared pool rather than creating a separate per-agent cap.
Space credit pool (daily + monthly + balance)
├─ Agent A ── spends ──┐
├─ Agent B ── spends ──┤──→ one shared total
└─ Agent C ── spends ──┘This means a busy agent can use more while a quiet one uses less — the Space budgets as a whole.
How usage is metered
Metered activity is tracked per Space across a few types — AI credits (model work agents do), storage (Drive used), posts/content, and members. Each run checks the relevant pool, deducts as it goes, and reports what remains. When a pool is exhausted, that action is blocked until the pool resets or you top up.
Rewards vs. Space credits
- Space credits — the daily/monthly grants from your plan plus purchased top-ups, shared by everyone in the Space.
- Rewards — credits you earn personally (referrals, onboarding, promotions). They sit in your personal balance and can be applied to a Space when you want to contribute them.
