Send the key in the X-API-Key header. Call the API from your server, never from a browser.
Each key allows 2 price requests per second (burst 4) and 1 quote request per second (burst 2).
A key is valid for 365 days. A wallet can have 3 active keys.
The key is shown once, when you create it. FlowRouter stores only its hash.
Your swaps carry your wallet's referral code for attribution. There is no fee.
For higher limits, or a fee or surplus share, contact us on X.
