## FAQ

### How do I call the Amazon EMR API?
Create a free Apizie key, then send POST https://www.apizie.tech/v1/cloud:amazonaws-elasticmapreduce/add-instance-fleet with the header x-api-key. Every endpoint returns { project, data, timestamp }.

### Is the Amazon EMR API free on Apizie?
Yes. The Free plan includes 1,000 requests a month at 100 requests a minute, no credit card. Amazon EMR itself also needs your own key from amazonaws.com.

### Can AI agents use the Amazon EMR API?
Yes. Add the Apizie MCP server (https://www.apizie.tech/mcp) to Claude, ChatGPT, Cursor or VS Code, then ask in plain language. The agent calls run_scraper with project key cloud:amazonaws-elasticmapreduce.

### What is the status of the Amazon EMR API?
Needs your own provider key (bring your own key)
