Gravatar API

healthy 4,061 Subscribers

Turn an email address into its Gravatar avatar and public profile. Pass an email and the service normalises it, computes the MD5 and SHA-256 hashes Gravatar uses, builds a ready-to-use avatar URL, checks whether a custom Gravatar actually exists, and fetches the public profile when present — display name, username, profile URL, location, about text, linked accounts and photos. A dedicated avatar endpoint builds just the image URL with full options: size (1-2048), a default image (identicon, monsterid, robohash, retro, mp, blank, 404, or your own URL), rating and force-default. Ideal for user-profile enrichment, comment systems, contact cards, team pages and onboarding — showing a real avatar from nothing but an email. A Gravatar lookup — distinct from deterministic avatar/identicon generation (avatar), which renders a brand-new image from a seed rather than fetching the avatar a person actually chose. No upstream key, no cache.

Avatar API

Generate deterministic avatars and identicons from any seed — the same seed always renders the exact same avatar, so user IDs, usernames or emails map to stable, unique profile pictures with no storage. 30 art styles (bottts robots, pixel-art, avataaars, identicon, lorelei, notionists, fun-emoji, shapes, rings and more), returned as ready-to-use SVG markup or a base64 PNG data-URI, with options for size, corner radius, background colour and flip. Backed by DiceBear. Ideal for default user avatars, comment/forum placeholders, dashboards, game characters, test fixtures and any UI that needs an instant, reproducible profile image.

Placeholder API

A fast, fully-local SVG generator for mockups and UIs: placeholder images (a sized rectangle with centered text and automatic contrast), initials avatars (with a deterministic colour derived from the name, in a circle or square), and identicon-style symmetric patterns generated deterministically from any seed. Every endpoint returns the JSON envelope or, with raw=1, the raw SVG so the URL can be used directly as an image source. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for prototypes, dashboards, user avatars, empty states and design systems.

Email Validation API

Verify email addresses without sending anything: RFC syntax validation, live MX-record lookup, disposable/throwaway detection (5,500+ domain blocklist), role-account and free-provider flags, "did you mean" typo suggestion, and a 0–100 deliverability score.

OIDC Discovery API

Inspect any OpenID Connect / OAuth 2.0 provider. Pass an issuer (a domain, an issuer URL, or the full discovery URL) and the service fetches the provider's discovery document at /.well-known/openid-configuration, parses every endpoint — authorization, token, userinfo, jwks, registration, end-session, introspection, revocation and device-authorization — together with the supported scopes, response types, grant types, ID-token signing algorithms, PKCE methods and claims, then fetches the JWKS and summarises its signing keys (count, algorithms, key types and key IDs), and reports a validity check with any issues. A second endpoint fetches and summarises any JSON Web Key Set on its own. The request is made server-side and private/internal targets are refused (SSRF-guarded). Built for SSO and OAuth/OIDC integration, identity-provider configuration debugging (Auth0, Okta, Keycloak, Azure AD, Google), security review and monitoring of signing-key rotation. An OIDC discovery / JWKS inspector — distinct from the JWT toolkit (jwt), the security.txt parser (securitytxt) and the HTTP security-header grader (secheaders). No upstream key, no cache.
