How the 0.05% swap fee works
The fee is a percentage of each swap, so it scales with what you trade and not with how often you ask for quotes. Quotes are covered by your plan's request limits. The monthly price buys throughput; the fee is the same 0.05% on Free and on Elite.
- $100 swap$0.05 fee
- $10,000 swap$5 fee
- $1,000,000 swap$500 fee

Requests per second and per minute
RPS is your burst
The most requests your key can send in any one second: quotes, swaps and transaction builds together.
RPM is your pace
The total across a minute. Starter's 10 RPS and 600 RPM let you hold 10 requests a second for the full minute.
Need more than Elite
If 100 RPS is not enough, or you need private endpoints or custom terms, talk to Carbium before launch.

Pricing questions
What you pay, what you get, and how to pick a plan.
How much does the Carbium Swap API cost?
0.05% per swap on every plan, plus a monthly plan price for throughput: Free $0, Starter $99, Pro $249 and Elite $999 a month, billed in USDC.
Is there a free plan?
Yes. Free costs $0 a month and gives you 1 request per second, 60 per minute and one API key, enough to integrate and test quotes and swaps.
Is the swap fee different on paid plans?
No. The fee is 0.05% per swap on Free, Starter, Pro and Elite alike. Paid plans raise the request limits and the number of API keys.
How is the 0.05% fee calculated?
As a percentage of each swap, so a $10,000 swap carries a $5 fee and a $100 swap carries $0.05. Quote requests do not add a fee; they count toward your plan's request limits.
What are RPS and RPM?
RPS is the most requests per second your key can send; RPM is the total per minute. Starter allows 10 RPS and 600 RPM, Pro 50 and 3,000, Elite 100 and 6,000.
How many API keys does each plan include?
Free includes 1 key, Starter 3, Pro 5 and Elite 10.
Which plan should a wallet, bot or trading team pick?
Free for testing. Starter for a wallet or app going live. Pro for bots and apps with steady traffic. Elite for high-volume bots and trading terminals that need 100 requests per second.
What currency are plans billed in?
USDC, monthly. The price is shown in USDC on each plan card.
Can I change plans later?
Yes. Upgrade or downgrade from the dashboard; the plan cards show Upgrade or Downgrade once you are signed in.
What if I need more than Elite?
Contact Carbium before launch about higher throughput, private endpoints or custom terms.
Start free, upgrade when you need throughput
