Use AIUsage with Anthropic Python SDK

One endpoint change. Under a minute. Same prompts, same outputs, 70–90% smaller Claude bill.

Setup

Get your AIUsage endpoint URL

Point Anthropic Python SDK at it

Paste this into your setup:

from anthropic import Anthropic

client = Anthropic(
    base_url="https://aiusage.ai/claude",
    api_key=os.environ["ANTHROPIC_API_KEY"],
)
# Same client.messages.create() calls — no code changes elsewhere.

Use Anthropic Python SDK normally

Every SDK method (messages, batches, tools) routes through AIUsage.

Your Anthropic API key stays yours. AIUsage forwards it transparently to Anthropic. It is never stored, never logged. You can delete your AIUsage account any time and your integration reverts to vanilla Claude in one env-var change.

What this gets you on Anthropic Python SDK

Every Anthropic Python SDK request that used to hit Anthropic at retail price now runs through AIUsage's audit layer first. On the six workloads we've verified, the measured delta was 76–84% on the same prompts. Your Anthropic Python SDK behavior — autocomplete, chat, agent mode, whatever — doesn't change.

Audit before you commit

The audit tool is free and shows you exactly what you would have paid. No signup required for the number. If your expected delta is under 40%, the tool tells you outright and you walk. Run the audit →
