Examples

Basic Gravatar URL:

npx tsx scripts/url.ts user@example.com

Custom size (200px):

npx tsx scripts/url.ts user@example.com --size=200

Use identicon for default:

npx tsx scripts/url.ts user@example.com --default=identicon

Force default image (ignore user's Gravatar):

npx tsx scripts/url.ts user@example.com --force-default --default=robohash

MD5 Hashing

Gravatar uses MD5 hash of the email address:

1. Convert email to lowercase
2. Trim whitespace
3. Compute MD5 hash
4. Use hex-encoded hash in URL

Example:

Email:   User@Example.COM
Step 1:  user@example.com
Step 2:  b48bf4373d7b7374351c0544f36f7fc3 (MD5)
URL:     https://www.gravatar.com/avatar/b48bf4373d7b7374351c0544f36f7fc3

Profile URLs

Gravatar also provides profile pages:

https://www.gravatar.com/{hash}

Replace /avatar/ with just the hash to get the profile page, which may contain additional information about the user.
