Ship with Claude in minutes

Plug your GoClaude key into the official Anthropic SDK. No proxy, no vendor lock — same endpoints, lower bill.

Quickstart

After purchase, we email your Claude API key within a few hours. Drop it into any environment variable your app already uses for Anthropic.

bash

export ANTHROPIC_API_KEY="sk-ant-..."   # the key we sent you

The key works with the official Anthropic SDK — no forks, no proxies, no custom base URL.

Python SDK

python

from anthropic import Anthropic

client = Anthropic()   # picks up ANTHROPIC_API_KEY

msg = client.messages.create(
    model="claude-sonnet-4-5",
    max_tokens=512,
    messages=[{"role": "user", "content": "Say hi in one word."}],
)
print(msg.content[0].text)

Node / TypeScript SDK

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

const client = new Anthropic();

const msg = await client.messages.create({
  model: "claude-sonnet-4-5",
  max_tokens: 512,
  messages: [{ role: "user", content: "Say hi in one word." }],
});

console.log(msg.content[0]);

Raw HTTP

bash

curl https://api.anthropic.com/v1/messages \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
