Configure OpenRouter for multi-user teams with per-user keys, budget controls, and usage attribution. Triggers: 'openrouter team', 'openrouter multi-user', 'openrouter organization', 'team api keys openrouter'.
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
Create a management key at openrouter.ai/keys and export it as OPENROUTER_MGMT_KEY.
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.
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).
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.
Gate expensive models per tier with the Model Governance allowlists (enforce_model_policy downgrades disallowed requests).
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.
Revoke keys for departed members with delete_team_key(key_hash) (DELETE /api/v1/keys/{hash}).

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.

Management key 403
Using API key instead of management key
Management keys are separate -- create one at openrouter.ai/keys
