How do I get started with claw.zip?

Run npx claw-zip init in your terminal. It will walk you through credential setup and configuration. You can also sign up at claw.zip and create your first API key from the dashboard.

Will compression change my model outputs?

Our compression is designed to preserve semantic meaning. For most use cases, outputs are identical. If you need guaranteed verbatim passthrough, you can disable compression per-key from the dashboard.

What happens if claw.zip goes down?

claw.zip runs on Cloudflare Workers across 300+ global edge locations. In the unlikely event of an outage, you can point your config back to the Anthropic API directly — no data is locked in our system.

Can I use claw.zip with non-Anthropic models?

Currently, claw.zip is optimized for the Anthropic API (Claude models). Support for additional providers is on our roadmap.

Integration Guide

Using claw.zip with the Anthropic SDK

The Anthropic SDK is the standard way OpenClaw users interact with Claude. claw.zip works as a drop-in proxy — change the base URL and you are done. This is the recommended starting point for any OpenClaw user looking to reduce their API costs immediately.

Before You Start

Prerequisites

→Anthropic SDK (TypeScript or Python)
→An OpenClaw API key
→A claw.zip account and API key

Step-by-Step

Integration Steps

Step 1

TypeScript SDK setup

For the TypeScript/JavaScript SDK, change the baseURL parameter.

typescript

import Anthropic from '@anthropic-ai/sdk';

const client = new Anthropic({
  apiKey: 'your_openclaw_key',
  baseURL: 'https://api.claw.zip',
  defaultHeaders: {
    'x-api-key': 'your_clawzip_key',
  },
});

Step 2

Python SDK setup

For the Python SDK, set the base_url parameter.

python

import anthropic

client = anthropic.Anthropic(
    api_key="your_openclaw_key",
    base_url="https://api.claw.zip",
    default_headers={
        "x-api-key": "your_clawzip_key",
    },
)

Step 3

Make requests as normal

All SDK features work identically. Messages, streaming, tool use, vision — everything is supported.

python

# Python example
message = client.messages.create(
    model="claude-sonnet-4-20250514",
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "What is prompt compression?"}
    ],
)
print(message.content[0].text)

Step 4

Check compression stats

The response includes headers showing compression performance.

typescript

// TypeScript - access raw response
const response = await client.messages.create({
  model: 'claude-sonnet-4-20250514',
  max_tokens: 1024,
  messages: [{ role: 'user', content: longPrompt }],
});

// Check your claw.zip dashboard for detailed stats:
// - Tokens saved per request
// - Compression ratio
// - Model routing decisions
// - Cost savings

Done

You Are All Set

That is it. One configuration change and all your OpenClaw API calls are now compressed through claw.zip. No code changes, no new dependencies, no breaking changes.
