OpenRouter Cost Controls

Overview

OpenRouter provides per-key credit limits, a credit balance API, and per-generation cost queries. Combined with client-side budget middleware, you can enforce hard spending caps at the key level and soft caps in your application. This skill covers key-level limits, per-request cost tracking, budget enforcement middleware, and alert systems.

Prerequisites

An OpenRouter API key (sk-or-v1-...) exported as OPENROUTER_API_KEY — see the openrouter-install-auth skill for setup

Python 3.8+ with the OpenAI SDK and requests; Node.js 18+ for the TypeScript per-request cost logger in the references

curl, jq, and bc for the balance check and the Budget Alert Script

An OpenRouter management key exported as OPENROUTER_MGMT_KEY if you provision per-key credit limits via POST /api/v1/keys

Instructions

Query GET /api/v1/auth/key per Check Credit Balance to see credits used, the key's limit, remaining balance, free-tier status, and rate limit.

Provision scoped keys per Per-Key Credit Limits — POST /api/v1/keys with a dollar limit (e.g. $50 for backend-prod) using the management key, then list keys to review usage against limits per service.

Deploy the BudgetEnforcer from Budget Enforcement Middleware: check_budget() rejects any request whose pre-flight estimate exceeds the per-request or daily cap, and record_cost() books the exact spend from GET /api/v1/generation?id=.

Cut unit cost with Cost-Saving Model Variants: :floor picks the cheapest provider, :free costs nothing where available, and the task-based ROUTING table sends classification to gpt-4o-mini and simple Q&A to Llama 3.1 8B.

Schedule the Budget Alert Script (cron) so a balance drop below the threshold fires an alert to Slack or PagerDuty.

Set max_tokens on every request and enable auto-topup per Enterprise Considerations to cap completion cost without risking an outage.

Check Credit Balance

# Current balance and limits curl -s https://openrouter.ai/api/v1/auth/key \ -H "Authorization: Bearer " | jq

Error	Cause	Fix
402 Payment Required	Credits exhausted	Top up at openrouter.ai/credits or use `:free` model
402 Key limit reached	Per-key credit limit hit	Increase key limit or create new key
Budget middleware rejects	Client-side limit exceeded	Increase limit or optimize prompt tokens
Stale pricing data	Cached rates outdated	Refresh from `/api/v1/models` daily
