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

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.
