Gravatar Lookup API

About the Gravatar Lookup API

Gravatar Lookup hashes the email address and fetches its public Gravatar profile: display name, username, bio, location, company, job title, pronouns and avatar. Linked accounts the owner has hidden from their profile page are still returned, flagged hidden. Paid plans add the linked social accounts and whether the email has its own uploaded avatar or only Gravatar's default image, a quick signal of a real, maintained identity.

What people use it for

Onboarding Form Prefill

When new members sign up, web apps pull display names, job titles, and avatars to prefill account profile pages.

Comment Section Avatars

Discussion forums match commenter email addresses to Gravatar thumbnail links to render author profile images beside every posted reply.

CRM Contact Enrichment

Sales teams populate lead records with company names, bios, and locations pulled directly from an inbound contact's work email.

Team Directory Setup

Populate internal employee directories by resolving company email addresses to official usernames, job roles, and profile photo URLs.

Request parameters — GET /v1/gravatarlookup

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

2

curl "https://api.apiverve.com/v1/gravatarlookup?email=hello%40apiverve.com" \
  -H "x-api-key: YOUR_API_KEY"

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Response — GET /v1/gravatarlookup

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.

Zero-code embed — one snippet, no backend

Drop an interactive Gravatar Lookup form onto any page. The widget calls the API for you, so no key ever appears in your markup and there is nothing to deploy.

Changelog — Gravatar Lookup API

Every change to this endpoint, newest first. Breaking changes ship as a new version and the previous one keeps serving — response fields are added, never removed or retyped in place, so an integration written against v1 keeps working.
