Member Portal — membership middleware for the Inference Cooperative

Reconciles three systems into one membership lifecycle:

System	Role	Source of truth for
Open Collective	Billing	Who is a paying member
Cloudron	Identity/SSO	Who can log in
LiteLLM	Inference	Who can use models, and how much

Architecture

Open Collective (billing)
        │ webhook
        ▼
┌─────────────────────────────┐
│  Member Portal (this app)   │
│  - OC webhook handler       │
│  - Cloudron user management │
│  - LiteLLM key management   │
│  - key-injection proxy      │
└─────────────────────────────┘
        ▲
        │ X-User-Email header (LibreChat forwards identity)
        │
LibreChat ──→ Member Portal ──→ LiteLLM ──→ backend

The three responsibilities

1. Webhook handler (POST /webhook/opencollective) — listens for Open Collective membership events and activates/deactivates members.
2. Key injector (/v1/*) — reads the member's email from the X-User-Email header, looks up their LiteLLM key, and forwards the request to the gateway with that key.
3. Admin (/health, /) — health and status.

Configuration (environment variables)

Variable	Purpose
CLOUDRON_API	Cloudron API origin (auto-set by Cloudron)
CLOUDRON_TOKEN	Cloudron API token (Read+Write)
MEMBERS_GROUP_ID	Cloudron group ID for members (grants chat access)
LITELLM_BASE	LiteLLM gateway URL
LITELLM_MASTER_KEY	LiteLLM master key
OPENCOLLECTIVE_WEBHOOK_SECRET	Optional webhook signature secret

Tier budgets

Governance decision (set in Loomio). Defaults:

• free — $2/month of tokens
• member — $15/month
• supporter — $30/month

LibreChat wiring

Point LibreChat's custom endpoint at this portal (not directly at LiteLLM), and add the identity header:

endpoints:
  custom:
    - name: "Inference Cooperative"
      apiKey: "${LITELLM_KEY}"
      baseURL: "https://portal.inference.coop/v1"
      headers:
        X-User-Email: "{{LIBRECHAT_USER_EMAIL}}"
      models:
        default: ["deepseek-v4-flash", "gpt-oss-120b"]
        fetch: true

Status

Scaffold — the three handlers are stubbed with the correct integration points. Remaining work before production:

• Verify Open Collective webhook event names + payload shape → order.processed (every payment), new member (first only), firstPayment flag
• Verify Cloudron user-creation API payload (role/group assignment) → POST /api/v1/users with {username, email, displayName, role, active} → group assignment via PUT /api/v1/users/:userId/groups with {groupIds: [...]}
• Add a persistent store (SQLite) for email→key mapping → key/list returns token strings (not objects), so we store email→token locally
• Verify LiteLLM key/generate + key/list payload shapes against live gateway → key/generate returns {key: "sk-..."}; key/list returns {keys: ["<token>", ...]}
• Add HMAC signature verification for the OC webhook (if OC supports it)
• Wire the OIDC addon for admin access
