Product A

The unified API gateway

One key routes to every major model provider. Top up a balance, spend it per token at OpenRouter-aligned list prices, and manage keys, usage and invoices in one console. Operated from Japan, for builders across the region and beyond.

Instant balance

Top up $100 and you hold roughly $100 of immediately spendable inference. Deducted per token as you call; top up again when it runs out.

OpenRouter-aligned pricing

List prices track OpenRouter's public price sheet model-for-model. No markup surprises — what you see there is what you pay here.

One integration

OpenAI-compatible endpoints for chat, completions and embeddings. Change the base URL, keep your SDK, swap models by slug.

Get started in three calls

  1. 1. Create a key. Sign up at the console and mint an API key in seconds.
  2. 2. Top up. Add balance by card or crypto; it is spendable immediately.
  3. 3. Call any model. Use the OpenAI SDK with our base URL and a model slug.
Python
from openai import OpenAI

client = OpenAI(
    base_url="https://api.jackz.ai/v1",
    api_key="JACKZ_API_KEY",
)

resp = client.chat.completions.create(
    model="deepseek/deepseek-v4-pro",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)
Node.js
import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.jackz.ai/v1",
  apiKey: process.env.JACKZ_API_KEY,
});

const resp = await client.chat.completions.create({
  model: "anthropic/claude-sonnet-5",
  messages: [{ role: "user", content: "Hello" }],
});
console.log(resp.choices[0].message.content);
