# Introduction

## Rate Limits

MiCA API keys are rate-limited per key. Exceeding the limit returns `429` with a `Retry-After` header. See [Rate Limits](/endpoints/rate-limits) for current thresholds.

## Caching

All responses include `Cache-Control` headers. List and statistics endpoints cache for 5 minutes, detail endpoints for 10 minutes. The `X-Data-Source` response header indicates whether the result was served from `cache`, `database`, or is `empty`.
