Question 1

What is an avatar API?

Accepted Answer

An avatar API is a service that retrieves user avatars programmatically. Instead of integrating with each social platform individually, an avatar API like unavatar lets you fetch avatars from GitHub, X, Instagram, Gravatar, and 36+ other providers through a single HTTP endpoint.

Question 2

Is unavatar free to use?

Accepted Answer

Yes. The avatar API is free for low-volume usage with 50 requests per day. Paid usage is metered — there are no minimums or subscriptions, you only pay for non-cached requests you actually make.

Question 3

How do I get an avatar from an email address?

Accepted Answer

Simply make a GET request to unavatar.io/email@example.com and the API will resolve the avatar from Gravatar, Google, and other email-based providers automatically. No API key is needed for the free tier.

Question 4

Do I need an API key?

Accepted Answer

Not for the free tier. Once you sign up for a paid plan, you get an API key that removes rate limits and unlocks extra features like custom TTL.

Question 5

What happens if an avatar can't be found?

Accepted Answer

A default fallback image is returned automatically. You can customize it by passing a fallback URL as a query parameter to match your app's style.

Question 9

How is unavatar different from Gravatar?
