API keys

A key is free and takes one email address. It raises your limits and lets you see your own usage.

You can call the API without a key, and for trying it out or building a small page you probably should. A key is for apps and sites that request many logos. It moves you from 60 to 300 logos a minute and from 1,500 to 50,000 a day, and from 20 to 300 new AI briefs a day. The limits then count for your key, not for the address your server shares with other people. There is no card and no paid plan; the pricing page has the comparison.

Getting a key

Go to the sign up page and enter your email address.
Open the message that arrives and follow its link. It confirms that the address is yours.
Choose a name and a password, and accept the terms.
Your account page shows the key and a list of your recent requests.

If you lose your password, the reset page sends a link to the same address.

Sending the key

Add it to the query string as api_key. It works on every endpoint, and it does not change the design, so a logo with a seed is identical with or without it.

A key that does not exist returns 401. The service does not quietly fall back to the anonymous limits, so a typo shows up at once.

Keeping a key safe

The key is part of the URL, so anyone who can see the URL can use your allowance. That includes anyone who opens the source of a page where you put it in an <img> tag. Use it where the request is made by your own server or your own build step, and keep it in an environment variable or a secrets store, never in a file in a public repository. For images shown in a public page, you do not need the key at all: pin seeds, and the images are cached and cost nothing against any limit.

If a key leaks, tell me through the contact page.
