# 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`
