Create a free Apizie key, then send POST https://apizie.tech/v1/cloud:amazonaws-kms/cancel-key-deletion with the header x-api-key. Every endpoint returns { project, data, timestamp }. ### Is the AWS Key Management Service API free on Apizie? Yes. The Free plan includes 1,000 requests a month at 100 requests a minute, no credit card. AWS Key Management Service itself also needs your own key from amazonaws.com. ### Can AI agents use the AWS Key Management Service API? Yes. Add the Apizie MCP server (https://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-kms. ### What is the status of the AWS Key Management Service API? Needs your own provider key (bring your own key)
