# OpenRouter Rate Limits

## Overview

OpenRouter rate limits are per-key, not per-account. Free tier keys get lower limits; paid keys get higher limits that scale with credit balance. The OpenAI SDK has built-in retry with exponential backoff for 429 responses. Check your current limits via `GET /api/v1/auth/key`. Rate limit headers are returned on every response.

## Prerequisites

- An OpenRouter API key (`sk-or-v1-...`) exported as `OPENROUTER_API_KEY` — see the `openrouter-install-auth` skill for setup
- `curl` and `jq` for querying your key's limits from `GET /api/v1/auth/key`
- Python 3.8+ with the OpenAI SDK (sync `OpenAI` and `AsyncOpenAI`) plus the `requests` package for reading rate-limit headers directly
- Awareness of your tier: free keys get 20 req/10s, keys with any credits 200 req/10s (see Rate Limit Tiers)
