Once you've decided to build with Fern, onboarding is straightforward: Create an account at [dashboard.fernhq.com](https://dashboard.fernhq.com/). Tell us a bit about your use case, and select a billing plan. If you're a Builder tier subscriber, pre-fund your billing wallet with USDC to access certain API functionality such as KYC or wallet creation. For subscribers on all other tiers, you can pre-fund billing wallets if desired; otherwise, we invoice you monthly. You can create API keys for sandbox (coming soon), pre-production, and production environments. Get started integrating the Fern API!
