Step 01

Generate Your Routebeam Unified API Key

Avoid managing complex payment cards or juggling multiple LLM vendor dashboards. With Routebeam, a single op_ API key gives you instant access to Claude 3.7 Sonnet, Claude 3.5 Sonnet, and OpenAI reasoning models.

One Unified Key

Use the same key across Claude Code CLI, Cursor, Windsurf, Cline, and backend pipelines.

Lifetime Non-Expiring Balance

Credits are added 1:1 and never expire at the end of the month. Zero minimum monthly commitment.

Step 02

Configure Shell Environment Variables

Claude Code reads standard Anthropic environment variables automatically. Simply point ANTHROPIC_BASE_URL to Routebeam's high-availability endpoint.

macOS / Linux (Bash / Zsh)

# Step 1: Set Anthropic Base URL & API Key in your shell
export ANTHROPIC_BASE_URL="https://routebeam.dev/v1"
export ANTHROPIC_API_KEY="op_your-routebeam-api-key"

# Step 2: Start Claude Code CLI seamlessly
claude

Windows (PowerShell)

# Step 1 (PowerShell on Windows): Configure Environment Variables
$env:ANTHROPIC_BASE_URL = "https://routebeam.dev/v1"
$env:ANTHROPIC_API_KEY = "op_your-routebeam-api-key"

# Step 2: Run Claude Code CLI
claude
Step 03

Anthropic SDK & IDE Integration (Cursor / Cline)

If you are building custom AI agents or configuring IDE extensions like Cursor, Cline, or Continue, configure the standard Anthropic SDK baseURL parameter directly.

import anthropic

# Initialize official Anthropic SDK with Routebeam Gateway endpoint
client = anthropic.Anthropic(
    base_url="https://routebeam.dev/v1",
    api_key="op_your-routebeam-api-key"
)

message = client.messages.create(
    model="claude-3-7-sonnet-20250219",
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Write a high-performance HTTP gateway worker."}
    ]
)

print(message.content[0].text)
Step 04

Break Free from 5-Hour Subscription Rate Limit Caps

Official subscription plans enforce severe 3-hour or 5-hour message limits that stall active coding sessions. Routebeam Gateway distributes requests across dynamic load-balanced pools, allowing developers to code continuously without hourly interruptions.

Formula: Official Reference Price × Published Group Discount %

Every token (input, output, cache-read, cache-write) is metered in real-time down to micro-USD (1 USD = 1,000,000 micro-USD) precision with zero hidden multiplier markups.

Frequently Asked Questions (FAQ)

How do I configure Claude Code to use a custom API proxy gateway?

Set export ANTHROPIC_BASE_URL="https://routebeam.dev/v1" and export ANTHROPIC_API_KEY="op_your-key" in your shell profile (e.g. ~/.bashrc or ~/.zshrc) before launching the claude CLI.

How does Routebeam solve official subscription hourly lockouts?

Routebeam routes requests across enterprise-grade high-availability pools with automatic failover, eliminating the 3-hour and 5-hour message caps seen in standard web accounts.

Does my balance expire?

No. Top-up balances remain active indefinitely with zero monthly expiration dates or subscription fees.

Are there any hidden markups or token multipliers?

None. Charges are calculated strictly based on the transparent formula: Official Reference Base Price × Published Discount %.
