OpenRouter Team Setup

Overview

OpenRouter supports team usage through per-user API keys with individual credit limits, management keys for programmatic key provisioning, and usage attribution via headers. This skill covers key provisioning, per-user budgets, usage tracking, and governance policies for multi-user deployments.

Prerequisites

• A management key (sk-or-v1-...) with provisioning rights exported as OPENROUTER_MGMT_KEY — created separately at openrouter.ai/keys; it can create/list/delete API keys but cannot call completions
• A regular OpenRouter API key exported as OPENROUTER_API_KEY for the shared-key attribution pattern — see the openrouter-install-auth skill for setup
• Python 3.8+ with the OpenAI SDK and requests; sqlite3 (stdlib) backs the per-user budget database
• curl and jq for the Team Key Dashboard Script

Instructions

1. Create a management key at openrouter.ai/keys and export it as OPENROUTER_MGMT_KEY.
2. Provision one key per team member via Key Provisioning via Management API — create_team_key(name, credit_limit) posts to /api/v1/keys; record the one-time key value and keep the key_hash for later listing/revocation.
3. Alternatively, keep a single shared key and attribute usage per user with the Shared Key with User Attribution pattern (X-Title: my-app:{user_id} header shows each user in the dashboard).
4. Enforce spend locally with Per-User Budget Enforcement — initialize the user_usage / user_budgets sqlite tables, call check_user_budget before each request and record_user_usage after.
5. Gate expensive models per tier with the Model Governance allowlists (enforce_model_policy downgrades disallowed requests).
6. Monitor continuously: run the Team Key Dashboard Script (curl + jq against /api/v1/keys) and generate the weekly Team Usage Report from the sqlite DB.
7. Revoke keys for departed members with delete_team_key(key_hash) (DELETE /api/v1/keys/{hash}).

Key Provisioning via Management API

import os, requests

MGMT_KEY = os.environ["OPENROUTER_MGMT_KEY"]  # Management key (cannot call completions)

def create_team_key(name: str, credit_limit: float = 25.0) -> dict:
    """Create a new API key for a team member."""
    resp = requests.post(
        "https://openrouter.ai/api/v1/keys",
        headers={"Authorization": f"Bearer {MGMT_KEY}"},
        json={"name": name, "limit": credit_limit},
    )
    resp.raise_for_status()
    data = resp.json()["data"]
    return {
        "key": data["key"],       # sk-or-v1-... (shown once)
        "hash": data["key_hash"], # For later identification
        "name": name,
        "limit": credit_limit,
    }

def list_team_keys() -> list[dict]:
    """List all keys with usage and limits."""
    resp = requests.get(
        "https://openrouter.ai/api/v1/keys",
        headers={"Authorization": f"Bearer {MGMT_KEY}"},
    )
    return [
        {
            "name": k.get("name"),
            "hash": k.get("key_hash"),

            "limit": k.get("limit"),
            "is_free_tier": k.get("is_free_tier", False),
        }
        for k in resp.json().get("data", [])
    ]

def delete_team_key(key_hash: str):
    """Revoke a team member's key."""
    resp = requests.delete(
        f"https://openrouter.ai/api/v1/keys/{key_hash}",
        headers={"Authorization": f"Bearer {MGMT_KEY}"},
    )
    resp.raise_for_status()

# Provision keys for the team
for member in ["alice-backend", "bob-frontend", "carol-ml"]:
    key_info = create_team_key(member, credit_limit=50.0)
    print(f"Created key for {member}: {key_info['key'][:20]}...")

Shared Key with User Attribution

from openai import OpenAI

# Alternative: single shared key with user identification via headers
def get_client_for_user(user_id: str) -> OpenAI:
    """Create a client that attributes usage to a specific user."""
    return OpenAI(

        api_key=os.environ["OPENROUTER_API_KEY"],
        default_headers={
            "HTTP-Referer": "https://my-app.com",
            "X-Title": f"my-app:{user_id}",  # User shows in dashboard
        },
    )

# Each user's requests appear under their X-Title in the dashboard
alice_client = get_client_for_user("alice")
response = alice_client.chat.completions.create(
    model="openai/gpt-4o-mini",
    messages=[{"role": "user", "content": "Hello"}],
    max_tokens=100,

Team Key Dashboard Script

#!/bin/bash
# Show all team keys with usage

echo "=== OpenRouter Team Keys ==="
curl -s https://openrouter.ai/api/v1/keys \
  -H "Authorization: Bearer $OPENROUTER_MGMT_KEY" | \
  jq -r '.data[] | "\(.name)\t$\(.usage // 0 | tostring)\t/\t$\(.limit // "unlimited" | tostring)"' | \
  column -t -s $'\t'

echo ""
echo "=== Total Usage ==="
curl -s https://openrouter.ai/api/v1/keys \
  -H "Authorization: Bearer $OPENROUTER_MGMT_KEY" | \
  jq '.data | map(.usage // 0) | add | "Total spend: $\(.)"'

Model Governance

# Define which models each tier can use
MODEL_ALLOWLISTS = {
    "free": ["google/gemma-2-9b-it:free"],
    "basic": ["openai/gpt-4o-mini", "meta-llama/llama-3.1-8b-instruct"],
    "pro": ["openai/gpt-4o-mini", "openai/gpt-4o", "anthropic/claude-3.5-sonnet"],
    "enterprise": None,  # None = all models allowed
}

def enforce_model_policy(user_tier: str, requested_model: str) -> str:
    """Enforce model allowlist based on user tier."""
    allowlist = MODEL_ALLOWLISTS.get(user_tier)
    if allowlist is None:
        return requested_model  # Enterprise: unrestricted
    if requested_model in allowlist:
        return requested_model
    # Downgrade to best allowed model
    return allowlist[-1]

Output

• Per-member API keys (sk-or-v1-..., shown once at creation) plus key_hash records carrying name, usage, and credit limit
• A team_usage.db sqlite database with per-user daily total_cost and request_count rows plus per-user budgets and model allowlists
• A columnar key dashboard from the curl + jq script: key name, spend, and limit per row, plus a total-spend line
• A weekly team usage report list sorted by weekly_cost, one dict per user with requests and daily limit

Examples

Provision keys for three team members with a $50 credit limit each:

for member in ["alice-backend", "bob-frontend", "carol-ml"]:
    key_info = create_team_key(member, credit_limit=50.0)
    print(f"Created key for {member}: {key_info['key'][:20]}...")
# Created key for alice-backend: sk-or-v1-a1b2c3d4e5...
# Created key for bob-frontend: sk-or-v1-f6a7b8c9d0...
# Created key for carol-ml: sk-or-v1-e1f2a3b4c5...

Each key value is only returned once — store it securely and keep the hash for revocation. More worked examples: references/examples.md.

Error Handling

Enterprise Considerations

• Use management keys for programmatic key provisioning -- they can create/list/delete API keys but cannot make completions
• Set per-key credit limits to prevent any single user from exhausting shared budget
• Use X-Title header with user identifiers for dashboard-level attribution
• Implement model allowlists per user tier to control access to expensive models
• Build weekly usage reports for cost visibility and anomaly detection
• Rotate team keys on a schedule; revoke keys for departed team members immediately
