Getting your API key

An API key lets you convert images programmatically. Here’s how to get one.

Steps

1. Create an account at Sign Up. All you need is an email address — we use passwordless sign-in codes.
2. Go to your dashboard at API Keys.
3. Click “Generate API Key”. Your key will be shown once — copy it immediately.
4. Store it securely. The key starts with kp_ followed by 40 hex characters. We store only a SHA-256 hash, so we can’t recover it if you lose it.

Key details

• Keys are free with no credit card required.
• Each key has 30 requests/minute and 500 requests/day limits.
• Anonymous (no-key) requests are limited to 10/minute and 50/day.
• You can generate multiple keys and revoke them individually.
• API keys are passed via the X-API-Key header.

Security

• Never commit API keys to version control.
• Use environment variables to store keys in your application.
• Revoke compromised keys immediately from your dashboard.

Once you have a key, the API quickstart has copy-paste examples in four languages, and the API playground runs real calls from your browser.
