## Transaction fees

All plans include the same transaction fee structure:

- **0% per transaction** — Senddy takes no percentage of payment volume
- **Network cost only** — Base gas runs under a cent per transfer, and relaying is
  gas-sponsored
- **No monthly minimums** — pay only for what you use
- **No international surcharges** — same rate worldwide

## Getting started

1. Create a Senddy account at [senddy.com/developer](/developer)
2. Your account starts on the **Free** plan automatically
3. Generate an API key from the Developer Dashboard
4. Upgrade when you need more capacity

## FAQ

### Can I switch plans anytime?

Yes. Upgrades take effect immediately. Downgrades take effect at the end of your current billing period.

### Is there a free trial for paid plans?

The Free plan gives you 1,000 API calls per month at no cost. This is enough to build and test your integration before upgrading.

### What happens if I exceed my API limit?

Requests beyond your limit will receive a 429 (rate limited) response. Upgrade your plan to increase your limit.

### What are the per-request rate limits?

Monthly quotas are separate from burst limits. The Free tier is capped at **60 requests per minute** and **10,000 per day**; higher tiers raise both. Exceeding either returns a 429.

### Do you offer volume discounts?

Yes. Contact us at **developers@senddy.com** for Enterprise pricing tailored to your volume.
