Claude Code Unlimited Setup Guide

Claude Code is one of the best AI coding tools today, but official account rate limits frustrate heavy users — you hit a rate limit mid-task and wait minutes to continue. This guide walks you through connecting via Zivv to eliminate limits entirely, in about 3 minutes.

Why Do You Get Rate Limited?

Official Claude enforces RPM (requests per minute) and TPM (tokens per minute) limits per account. When Claude Code does large refactors or reads multi-file context, a single session can max out the quota and trigger limits repeatedly. Zivv smooths this out via account pool rotation, fully transparent to you.

Quick Start (3 Minutes)

Step 1: Sign Up and Top Up

1. Visit zivv.pro
2. Register with your email
3. Top up from as little as ¥10

Step 2: Create an API Key

1. Log in, go to the "API Key" page
2. Create a new key (any name)
3. Copy the key value in sk-xxx format and store it safely

Step 3: Configure Claude Code

Claude Code switches backends via two environment variables. Point them at Zivv.

Set the environment variables, then launch Claude Code:

export ANTHROPIC_BASE_URL=https://zivv.pro
export ANTHROPIC_AUTH_TOKEN=sk-your-key-here
claude

Windows PowerShell:

$env:ANTHROPIC_BASE_URL="https://zivv.pro"
$env:ANTHROPIC_AUTH_TOKEN="sk-your-key-here"
claude

To persist, add the first two lines to ~/.bashrc / ~/.zshrc (or system environment variables on Windows).

Step 4: Configure Codex (Optional)

Codex uses the OpenAI protocol, which Zivv also supports. Set the environment variables, then launch:

export OPENAI_BASE_URL=https://zivv.pro/v1
export OPENAI_API_KEY=sk-your-key-here
codex

Windows PowerShell:

$env:OPENAI_BASE_URL="https://zivv.pro/v1"
$env:OPENAI_API_KEY="sk-your-key-here"
codex

The same Zivv key drives both Claude Code and Codex — no separate signup needed.

Step 5: Verify

Type any prompt in your editor; a normal response means you're connected. From the CLI:

claude "Explain closures in one sentence"

FAQ

Q: Could my data leak? A: No. Zivv does not store prompt or response bodies — only usage for billing. All requests are encrypted in transit.

Q: Will the account pool run out and cut off service? A: No. Continuously replenishing accounts is core to Zivv's operation, with dedicated monitoring of pool size and health.

Q: How do I switch back to official? A: Remove or restore those two environment variables — instant switch, no interference.

Q: Which models are supported? A: The full Anthropic lineup (Opus / Sonnet / Haiku) plus OpenAI and Gemini — all callable with one key.
