## Understanding credits

1. **Monthly allowance:** Your subscription gives you 100,000 free credits each month.
2. **Usage:** Health & Fitness API usage consumes credits, based on connected users and events.
3. **Monthly reset:** Credits reset to 100,000 each billing period and do not roll over.x
4. **Scaling:** Only pay for credits beyond your 100,000 monthly allowance. Additional usage is billed monthly.
5. **Volume Discount:** The more credits you use, the cheaper each one gets (tiered pricing).

### Terra’s pricing scales with your business

Your Terra subscription includes 100,000 monthly credits - covering the needs of most startups during their initial launch and growth phases. Tiered pricing applies beyond this:

| **Total Monthly Credits Consumed** | **Cost per Additional Credit** |
| ---------------------------------- | ------------------------------ |
| 0 - 100,000                        | $0 (Included in subscription)  |
| 100,001 - 1,000,000                | $0.005                         |
| 1,000,001+                         | $0.003                         |

## Unexpected usage spike led to a surprise bill?

**Usage Spike Protection has your back.**

* We understand that rapid growth (especially for startups) or testing errors can cause unforeseen costs. That's why our **Usage Spike Protection** is here to ensure you're not penalised.
* If you receive an **unexpectedly large bill** in your **initial 6 months** due to a significant spike from rapid user growth or a testing/integration error, you may be eligible for a **one-time refund**. (Specific criteria apply, such as bill threshold or usage increase).
* Simply reach out to our support team. We'll review your situation, work towards refunding the unexpected amount, and help you optimise future usage.
* **We believe in growing** with our developers **for the long term**, and that means supporting you when things take off faster than planned, or when something simply goes wrong.
