​
Step 1: Navigate to Homepage

Start by visiting https://tinfoil.sh/ and click the “Get Started” button in the top right corner.

​
Step 2: Log In or Sign Up

Create an account with your email or one of the social connections. If you already have an account, click “Sign in” instead.

​
Step 3: Access Your Dashboard

Once logged in, click the “Dashboard” button in the top right corner. The dashboard opens on the Home page.

​
Step 4: Open API Keys

Select “API keys” in the sidebar. API access is enabled automatically, so there is nothing to activate and no payment method is required to get started.

​
Step 5: Copy Your Default API Key

If your account has no API keys yet, opening API keys creates a “Default API key” and shows it in a “You’re all set!” dialog. Click the eye button to reveal the key or the copy button to copy it. You can also copy the setup prompt to hand to an AI coding agent. Click “View API keys” to close the dialog and see your keys.

​
Step 6: Create Additional API Keys

Select “API keys” in the sidebar and click “Create API key”. Enter a name, then optionally set an expiration, token limits, or a spend limit. Key limits count the key’s lifetime usage and never reset. Click “Create API key” to finish.
Use descriptive names like “Production”, “Development”, or “Mobile App” to easily identify your keys later.

​
Step 7: Copy Your API Key

Your new API key appears in the list. Hover over the key and click the copy button to copy it, or the eye button to reveal the full key. Use “Edit” to rename a key or change its limits, and “Delete” to revoke it.

​
Step 8: Manage Billing

Select “Billing” in the sidebar to check your credit balance, view your current spend, manage subscriptions and payment methods, redeem promo codes, and review transactions. Buy credits or turn on Auto-reload from the Credits and limits section to keep API access. The Credits and limits section also lets you set a usage limit that pauses API access for every key once spending in the current billing period reaches it. A key’s own spend limit does not lift this pause; raise the usage limit instead. The limit is checked against completed requests, so requests already in progress finish and are billed; see How usage is recorded.
