#profile

Live public profile and language-learning stats from Duolingo, the world's largest language-learning platform — no key, nothing stored. This is the gamified-learning social view: a learner's XP, daily streak, courses and progress, distinct from every other social platform in the catalogue. The user endpoint returns a profile summary — display name, bio, location, join date, total XP, the current daily streak, the language being learned and the from-language, the current course, Super/Plus status and a course count. The courses endpoint returns the per-language breakdown: every course the learner studies with its title, learning and from languages, XP earned and crown count. The streak endpoint returns the streak detail — the current streak length and, when the learner makes it public, the streak start date and longest streak. Lookup is by username; the official mascot account "duo" is always available. Build streak widgets, learning-accountability bots, language-club leaderboards and profile cards on top of real Duolingo data. Private or non-existent usernames return a clean 404.

Live profile and notes for any Nostr account, read straight from the open Nostr relay network — no key, no account, nothing cached. Nostr is the decentralised, censorship-resistant social protocol with no central server, so this service queries several public relays in parallel and merges and de-duplicates what they return. Give it a public key, either as 64-character hex or as an npub… key (it decodes bech32 npub keys for you), and the profile endpoint returns the account's kind-0 metadata: name, display name, about/bio, picture, banner, website, NIP-05 verified identifier and Lightning address — fiatjaf's key resolves to name "fiatjaf", NIP-05 [email protected]. The notes endpoint returns the account's most recent kind-1 text notes — the posts — newest first and de-duplicated across relays, each with its content, timestamp, note id and mention and reply counts. The relays endpoint lists the public relays queried. This is the profile-and-posts layer for any Nostr client, bot, indexer or social dashboard — live from the relay network, nothing stored. Distinct from centralised-platform social APIs — this reads the open Nostr protocol directly from its relays. 4 endpoints.

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.
