# OpenRouter Common Errors
## Overview
OpenRouter returns standard HTTP error codes plus OpenRouter-specific error codes in the response body. The most common: 401 (auth), 402 (credits), 429 (rate limit), 400 (bad request), and 5xx (upstream provider errors). Each error includes a `code` field and a human-readable `message`. This skill covers every common error, its root cause, and the exact fix.
## Prerequisites
- An OpenRouter API key (`sk-or-v1-...`) exported as `OPENROUTER_API_KEY` — see the `openrouter-install-auth` skill for setup
- `curl` and `jq` to run the Diagnostic Script
- Python 3.8+ with the OpenAI SDK for the categorized error handler; Node.js 18+ for the TypeScript typed-error classifier in the references
- The `requests` package if you use the Prevention Middleware's pre-flight model check
## Instructions
