## FAQ

### How do I call the AWS Lambda API?
Create a free Apizie key, then send GET https://zieapi.vercel.app/v1/cloud:amazonaws-lambda/get-layer-version-policy with the header x-api-key. Every endpoint returns { project, data, timestamp }.

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

### Can AI agents use the AWS Lambda API?
Yes. Add the Apizie MCP server (https://zieapi.vercel.app/mcp) to Claude, ChatGPT, Cursor or VS Code, then ask in plain language. The agent calls run_scraper with project key cloud:amazonaws-lambda.

### What is the status of the AWS Lambda API?
