Migrate from xAI Grok Console to Railwail

TL;DR — Switch in Under 5 Minutes

• xAI's API is already OpenAI-compatible — change baseURL only
• Grok 2, Grok 3, Grok 3 Mini, Grok Vision all available on Railwail
• EU-hosted, EUR billing
• Plus access to Claude, GPT-4o, Gemini, Llama through the same key
• Same streaming, tool calling, vision behaviour

Why Move Off xAI Grok Console?

xAI's Grok models are competitive on reasoning and have unique X/Twitter integration. The constraints: US-only routing, USD billing, narrow catalog (Grok only), and no closed-source alternatives in the same account. Railwail mirrors Grok via the OpenAI-compatible schema and adds the rest of the market.

Step 1 — Get a Railwail API Key

Sign up at railwail.com and generate a key.

Step 2 — Change Base URL

TypeScript / JavaScript

Before (xAI):

import OpenAI from "openai";

const xai = new OpenAI({
  apiKey: process.env.XAI_API_KEY,
  baseURL: "https://api.x.ai/v1",
});

const res = await xai.chat.completions.create({
  model: "grok-3",
  messages: [{ role: "user", content: "Hello" }],
});

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.RAILWAIL_API_KEY,
  baseURL: "https://api.railwail.com/v1",
});

const res = await client.chat.completions.create({
  model: "grok-3",
  messages: [{ role: "user", content: "Hello" }],
});

Python

from openai import OpenAI

client = OpenAI(
    api_key=os.environ["RAILWAIL_API_KEY"],
    base_url="https://api.railwail.com/v1",
)

resp = client.chat.completions.create(
    model="grok-3",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)

cURL

curl https://api.railwail.com/v1/chat/completions \
  -H "Authorization: Bearer $RAILWAIL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "grok-3",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Why Railwail Over xAI Console

• EU hosting and EUR billing
• Same OpenAI-compatible API — no SDK to change
• Adds Claude, GPT-4o, Gemini, Llama, DeepSeek
• Built-in playground for A/B testing Grok vs alternatives
• Per-key rate limits and spend caps
• Unified VAT invoice

FAQ

Does Grok's live X/Twitter search work?

The live X-data retrieval mode is xAI-internal and not exposed via Railwail. For grounded responses, use Perplexity Sonar models on Railwail (perplexity-sonar-pro) for general web search grounding.

What about Grok's reasoning_effort parameter?

reasoning_effort (low / high) is forwarded to grok-3 models. Higher effort spends more tokens internally but produces better reasoning.

Is vision (image input) supported?

Yes. Pass content as an array with text and image_url blocks (OpenAI vision schema) to grok-2-vision or grok-3-vision.

Does Grok-Image (image generation) work?

Yes. POST /v1/images/generations with model=grok-image-1 returns generated images.

What about tool calling?

Standard OpenAI tools array works on Grok 3. tool_choice (auto / none / specific) is supported.
