APICostCalc is free to use. To keep it that way, some links on this site are referral or affiliate links. Here's exactly how that works — no surprises.
When you sign up to a service through one of our links (for example a crypto exchange in our exchange API guides, or a developer tool we recommend), we may earn a small commission or a share of fees. It costs you nothing extra — and you often get a sign-up discount or bonus.
1. We only recommend things we'd use. A commission never buys a better review.
2. Prices and facts stay honest. Our pricing tables and comparisons are based on official sources, not on who pays us.
3. Affiliate links are marked with rel="sponsored" and labelled where they appear.
4. The cheapest option wins. If a free or non-affiliate tool is the better answer, we say so.
Nothing on APICostCalc is financial, investment or professional advice. Crypto trading and leverage are risky. Always do your own research and read each provider's terms.
