How it works with Claude Code.

You already have Claude Code installed. This just makes it cheaper.

Paste your Anthropic key

Same key you already use for Claude Code. Encrypted at rest (AES-256-GCM), per-user. We never log raw keys or prompts.

Run one terminal command

Copy the one-liner from your dashboard. It points Claude Code at our endpoint instead of api.anthropic.com. Nothing else changes.

Keep using Claude Code

Your agent loops, slash commands, tool use, file edits — all identical. The only difference is your Anthropic invoice at the end of the month.

# one line — paste from your dashboard
curl -s https://aiusage.ai/install | sh

# then use Claude Code exactly like you already do

Nick runs Claude Code 6–8 hours a day. He was the first one to paste a key and top up.

"Claude Code was burning through my Anthropic credits in a week. I pasted my key into aiusage, ran the one-liner, kept working. Same Claude Code, same output — except now the same $50 of credits lasts me a month instead of four days. Feels like cheating."

Questions from Claude Code users.

Do I have to change my Claude Code config?

One environment variable, set by the one-line installer. Your slash commands, model preferences, settings.json — untouched.

Does tool use / file editing / agent loops still work?

Yes. Streaming, tool use, vision, agentic loops — the whole Claude Code surface area works unchanged.

What Claude models are supported?

All current Sonnet and Haiku models, including the 1M context variants.

Is my Anthropic key safe?

Encrypted at rest (AES-256-GCM), never logged in plaintext. You can rotate or delete it from your dashboard anytime.

What if I want to go back to api.anthropic.com?

Unset one env var. You're back on direct Anthropic billing. Nothing in your project changes.
