Frequently Asked Questions

Is this API exactly the same as the original Anthropic API?

Yes. The endpoint structure (/v1/messages), header parameters and JSON response formats are 100% identical. It works as a drop-in replacement with your existing Anthropic SDK or tools.

How do I use it with Cursor IDE and Claude Code CLI?

In Cursor settings, change the Anthropic Base URL to https://anon4me.com/v1 and add the API key you created. For Claude Code, simply set the ANTHROPIC_BASE_URL environment variable in your terminal.

How do payments and balance top-ups work?

From your dashboard you can top up any amount via credit/debit card or USDT crypto transfer. Your balance is drawn down as you use it and never expires.
