feat: age verification with an ID document (Didit), and closed registration
Age: a Didit provider behind the vendor-neutral age interface. A person
verifies once (ID document, passive liveness, face match) and all their
linked IMVU accounts count as adult. Webhooks are checked against Didit's
signatures; only "over 18" is kept. A later answer replaces an earlier one
(an approval taken back is revoked). Checks are limited: one unfinished
check per person, 3 in 30 days, none once verified, and a monthly cap
(DIDIT_MONTHLY_LIMIT, default 30: Didit's free plan is $10 of credit a
month and a check costs $0.30). The Account page gets an Age Verification
card.

Registration: open or closed, an admin's setting in the console
(default from REGISTRATION). Closed: new accounts can only sign in until
a moderator approves them (or declines, deleting the account); the
website shows them a waiting page and the API treats them as signed out.

The hub's API

apps/api (Elysia on Bun). The route definitions in apps/api/src/app.ts are the reference: their schemas validate requests and type the website's client (Eden). This is the overview.

  • /api/auth/*: Better Auth (accounts, sessions, device sign-in, JWT keys).
  • /api/v1/*: the hub's own routes.

The website reaches the API through its own origin (Next.js rewrites /api to it), so sessions are first-party cookies. T5DE's proxy calls it directly with Authorization: Bearer <session token>.

Errors are {"error": "<code>", "message": "<text for people>"} with a 4xx/5xx status; message can be shown as is. Codes: invalid, signed_out, forbidden, not_found, no_such_imvu_account, already_linked, code_missing, expired, link_cap, rate_limited, imvu_unavailable, unknown_product, hosted_room.

Accounts (Better Auth)

POST /api/auth/sign-up/email {email, password, name, username}. Usernames 3-32 of A-Za-z0-9_; passwords 10-256 characters. The first account is an admin. With registration closed, the others wait for approval (approved: false): every route but /me answers 403 awaiting_approval, and the rest of the hub treats them as signed out.
POST /api/auth/sign-in/username {username, password}
POST /api/auth/sign-out
GET /api/v1/me {person} (approved false while waiting), with picture: the avatar picture of their first linked IMVU account (from IMVU, kept an hour), or null
GET /api/v1/hub (anyone) {registration}: open or closed

Proxies

POST /api/auth/device/code {client_id: "t5de-proxy"} → {device_code, user_code, verification_uri, verification_uri_complete, interval, expires_in} (RFC 8628). verification_uri is the website's /device.
POST /api/auth/device/token {grant_type: "urn:ietf:params:oauth:grant-type:device_code", device_code, client_id} → {access_token} (a session token, used as a bearer token) or {error: authorization_pending | slow_down | expired_token | access_denied}
POST /api/v1/device/approve (website, signed in) {code}: signs the waiting proxy in as this person
POST /api/v1/badges (bearer or website session) {imvuIds} (at most 200 IMVU account IDs) → {badges}: those linked to a T5DE account that turned on showBadge for them and isn't banned. Nothing else about them. 120 a minute per person.
GET /api/v1/realtime WebSocket, bearer token: presence, outfits, the room channel, decoration notices (decor) and hosted rooms (room.*, docs/hosted-rooms.md). Protocol in apps/api/src/realtime.ts.
GET /.well-known/jwks.json the Ed25519 keys JWTs are signed with

Website routes (signed in unless noted)

GET /api/v1/home (anyone) {onlineCount, links?}
GET /api/v1/online (anyone) {online}: accounts showing they're online (moderators see all, with hidden)
GET /api/v1/online/events (anyone) server-sent events: online with {online} now and on each change
GET /api/v1/rooms (anyone) {rooms}: listed IMVU rooms of T5DE users, with the T5DE users in each now (AP rooms for adults only)
GET /api/v1/account {person, links, challenges, computers, canLink}
POST /api/v1/account/links {username} → 201 {challenge} (the tagline code)
POST /api/v1/account/links/:imvu/check {link, moved}
DELETE /api/v1/account/challenges/:imvu cancel linking
PATCH /api/v1/account/links/:imvu {showBadge?, showPresence?, listRooms?} → {link} (each off by default; showBadge: others see the T5 badge on this account in the client)
POST /api/v1/account/links/:imvu/recheck {link} (age checked with IMVU again)
DELETE /api/v1/account/links/:imvu unlink
POST /api/v1/account/signout-computers signs T5DE out on all their computers

Hosted rooms

Rooms the hub hosts (docs/hosted-rooms.md, which has the details and the realtime part). Bearer or website session; the GETs also signed out.

POST /api/v1/hosted-rooms {name, description?, roomPid, rating, maxUsers?, imvuId, privacy?} → 201 {room}. imvuId: one of the person's linked accounts, shown as owner. Name 1-64 characters, description up to 512 (plain text), maxUsers 2-30 (default 10), rating general or adult (adult people only). Up to 10 open rooms a person (room_cap), 20 new ones an hour.
GET /api/v1/hosted-rooms {rooms}: open rooms, newest first (at most 200): public ones, and private ones the person owns or moderates; adult ones for adults only. ?mine=1: the person's own; ?favorites=1: their favorites; ?recent=1: the last 20 they joined.
GET /api/v1/hosted-rooms/:n {room, scene: {contents, hash}, myRating}; 404, or 410 closed
PATCH /api/v1/hosted-rooms/:n (owner) {name?, description?, rating?, maxUsers?, roomPid?, privacy?, moderators?} → {room}. Made adult: non-adults in it are sent out.
PUT /api/v1/hosted-rooms/:n/scene (owner) {contents, roomPid?} → {room, scene}. contents: up to 500 [furniture ID, product ID (integer or hub ID), placement (up to 200 characters)]. 60 a minute.
DELETE /api/v1/hosted-rooms/:n (owner or moderator) closes it for good; everyone in it gets room.closed
GET .../:n/participants, GET .../:n/bans, DELETE .../:n/bans/:imvu, GET/PUT/DELETE .../:n/image, PUT/DELETE .../:n/favorite, PUT/DELETE .../:n/rating Phase 2: docs/hosted-rooms.md, "Phase 2"

A room is {n, instanceId, chatId, name, description, roomPid, rating, maxUsers, ownerImvuId, ownerName, occupancy, privacy, moderators, moderatorNames, image, favorite, score, ratings, createdAt}; instanceId is <owner IMVU ID>-<2100000000 + n>, chatId 2100000000 + n, occupancy the people in it now.

Decorations

T5 products placed in ordinary IMVU rooms (docs/products.md, "Decorations"). instance is IMVU's room instance, <owner's customer ID>-<n> (^[1-9][0-9]{0,11}-[1-9][0-9]{0,9}$); hosted rooms' (room number 2100000000 and up) are refused (400 hosted_room: they have their own scene). A room's decorations are {instance, contents, hash}: contents is a list of [furniture instance ID (integer), hub product ID, placement (up to 200 characters)], hash the sha256 (hex) of contents as JSON.

GET /api/v1/decorations/:instance (anyone, also signed out) the room's decorations as the viewer sees them: only products with a revision that isn't retracted, adult ones only for people with an adult account. A room without any: contents: [].
GET /api/v1/decorations?instances=a,b (anyone) {rooms: [{instance, contents, hash}]}, up to 20 rooms, in the order asked
PUT /api/v1/decorations/:instance (bearer or website session) {contents} → the room's decorations as the person sees them. Only if one of the person's linked IMVU accounts is the room's owner (else 403 forbidden). Up to 300 items, each furniture ID once; every product must be registered (400 unknown_product). An empty list removes them. Everyone with a chat in the room gets {"type": "decor", "room": instance} on the realtime connection. 60 a minute.

Products, catalogs and libraries

The routes and tokens are in docs/products.md. Products are {id, name, description, rating, latest, creator, creatorUsername, parent, image, categories, createdAt, updatedAt}; parent, image and categories come from the latest revision (its IMVU parent's public info). GET /api/v1/products takes q, creator, category (an IMVU category ID) and limit (1-200, default 60).

Age verification

Vendor-neutral (docs/design.md, "Age"): IMVU's answer is recorded when an account is linked or checked again; person-level providers (phone wallets, document checks) are started here.

GET /api/v1/age {providers: [{id, label, vendor, scope}], checks}: the providers in use and the person's own checks (newest first; status pending, complete, failed or revoked)
POST /api/v1/age/:provider/start {returnURL} (a path on the website, or an address on it) → {kind: "done"}, {kind: "redirect", url, ref} (send the person there) or {kind: "browser", request, ref} (hand request to the browser's Digital Credentials API). An unfinished check is given again. 409 refused: already verified, or a limit reached (message says which); 502 provider_unavailable
POST /api/v1/age/:provider/complete {ref, response}: the browser's answer, for wallet providers
POST /api/v1/age/webhook/:provider the provider's webhook; the provider checks its signature (401 if it isn't the provider's). A later answer replaces an earlier one (an adult answer taken back is revoked)

Console (moderators; roles: admins)

GET /api/v1/console {counts, connections, online, audit}
GET /api/v1/console/people?q=&waiting=true {people} (waiting: only accounts waiting for approval)
POST /api/v1/console/people/:id/approve {person}
POST /api/v1/console/people/:id/decline an account waiting for approval: deletes it
GET /api/v1/console/settings, PUT (admins) {registration}: open or closed (default: the API's REGISTRATION, else open)
GET /api/v1/console/people/:id {person, links, computers}
POST /api/v1/console/people/:id/link-cap {linkCap} (0-1000)
POST /api/v1/console/people/:id/ban {reason}; only admins ban moderators
POST /api/v1/console/people/:id/unban
POST /api/v1/console/people/:id/role (admins) {role}
