Fusion uses a credit-based billing system. Credits are the currency for all platform actions — publishing quests, storing data, running experiments, and more.
How Credits Work
| Concept | Value |
|---|
| 1 credit | 1 cent |
| Starter bonus | Free credits for every new organization |
What Costs Credits
The following actions consume credits from your organization’s balance:
| Action | Category |
|---|
| Publish a quest | Quest & Experiments |
| Participant joins a quest | Quest & Experiments |
| Experiment data submission | Quest & Experiments |
| Brain recording (EEG) | Data Collection |
| Prompt response stored | Data Collection |
| Health data sync (wearable) | Data Collection |
| Dataset storage | Storage |
| AI data analysis | Analysis & AI |
| Analysis script execution | Analysis & AI |
Free Actions
These actions are free and do not consume credits:
- Creating a quest (draft)
- Editing a quest
- Adding prompts and experiments
- Configuring onboarding
- Onboarding responses (no charge)
- Viewing data in the dashboard
- Adding organization members
Re-Publishing Is Free
The first time you publish a quest, it costs credits. Re-publishing the same quest (after unpublishing and making changes) is free — the system checks for a prior publish transaction.
Debt Tolerance
Some operations allow a small amount of debt to prevent data loss:
| Action | Debt Allowed |
|---|
| Publishing a quest | ❌ No — strict check, returns error if balance too low |
| Data collection (experiment, prompt, EEG, etc.) | ✅ Yes — small debt allowed |
Data collection actions never fail due to insufficient credits. The system allows a small amount of debt so participant data is never lost. Publishing, however, requires a sufficient balance.
Low Balance Warning
When your organization’s credit balance is running low, an amber warning appears on the dashboard:
“Your credit balance is running low. Add credits to continue using premium features.”
