How this service works
Gravatar lookup: whether an email has a Gravatar, with avatar and profile URLs. Input: an email address.
Output
A JSON object containing: has_gravatar (boolean indicating whether the email has an active Gravatar), avatar_url (direct image URL with size and identicon fallback parameters), profile_url (link to the Gravatar profile page), and email_hash_sha256 (the SHA-256 hash of the normalized email used by Gravatar).
Example use cases
Enrich user profile with avatar
“I have a new user who signed up with sarah.kim@gmail.com — can you check if she has a Gravatar and grab her avatar URL so I can display it in her profile?”
Verify contact has public avatar
“Before I send this email to mark.jones@company.com, can you check if he has a Gravatar profile I can link to in my CRM?”
Bulk contact avatar enrichment
“I'm building a team directory and need to check if alex.tran@myorg.com has a Gravatar set up — fetch the avatar and profile URL if available.”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/gravatar?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, lightweight check on whether a specific email address is associated with a Gravatar profile, and want to retrieve the avatar and profile URLs in a single call. Prefer this over manually computing the SHA-256 hash and constructing Gravatar URLs yourself, especially in agent workflows where you need to enrich contact or user data with public avatar information.
Side effects
- Invalid or malformed email address returns an error or unexpected hash
- Email exists but has no Gravatar — has_gravatar returns false, avatar_url still returns an identicon fallback
- Network timeout reaching the Gravatar service
- Gravatar service downtime causing lookup failure
- Email with unusual Unicode characters may not normalize correctly
