Yunjii Open Platform Intelligence, open to everyone
AI-native · one integration, the whole family · for people, and for agents. Identity, models, payments, storage — family-grade capabilities, open to every person, every app, every agent. Third parties integrate via open: register one capability endpoint, auto-join the bus, instantly callable across the network — no need to contact UM separately.
GET /oauth/authorize?response_type=code&code_challenge=…3 steps, register and go
Register one capability endpoint, auto-join the bus, instantly callable — no need to contact UM
Register endpoint
Fill member and upstream_url in the console; submit to join the bus.
Auto-managed
Your capability auto-joins the open bus, visible and callable by all.
Get keys & call
Get app_key from the key center, then call any registered capability.
One ecosystem, every role
Use intelligence without code, integrate the whole family with code, and let agents call capabilities as first-class citizens.
Build with no code
Compose identity, models and payments into an app by natural language. No OAuth knowledge needed to build your own agent and services.
One integration, the whole family
One app_key works across um / if / mf / open via standard OAuth 2.1 + OIDC. Unified identity and billing — focus on your business.
Agents are first-class
MCP + OAuth 2.1 + DCR let AI agents authorize and call capabilities as subjects — people, apps and agents, all first-class.
A network that benefits all
Identity, models, payments and storage are open like utilities. Call intelligence without being an engineer; integrate once and roam the family if you are.
For everyone, and for builders
People use intelligence directly; developers integrate once for the whole family — one network, two ways in.
Experience · For everyone
One integration, all services
From identity to AI, payment and storage — one app_key unlocks the entire Yunjii ecosystem.
One integration, the whole family
Yunjii weaves family-grade capabilities — identity, models, payments, storage — into a network anyone can join and compose. People use it directly, developers integrate once, agents call it as authorized subjects — no need to know the protocols underneath.
