Top up your balance

Top up your Rupiah balance from Rp 10,000 via QRIS or crypto (USDT / USDC). The balance never expires and is billed per token as you use it — no subscription. Model rates have no markup; the service fee and any QRIS or crypto network fee are shown separately before payment.

Create an API key

In the dashboard, open API Keys and create a new key. It looks like sk-nexo-....

First request

Easiest path: the OpenAI endpoint (/v1/chat/completions) — it works for every model, including Claude. Not sure which to pick? See Endpoints & Formats.

from openai import OpenAI
 
client = OpenAI(base_url="https://api.nexotao.com/v1", api_key="sk-nexo-...")
 
resp = client.chat.completions.create(
    model="qwen3-coder-next",  # or claude-opus-4-6, nova-micro, etc.
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)

curl https://api.nexotao.com/v1/messages \
  -H "x-api-key: sk-nexo-..." \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-opus-4-6",
    "max_tokens": 256,
    "messages": [{"role": "user", "content": "Hello"}]
  }'

import OpenAI from "openai"
 
const client = new OpenAI({ baseURL: "https://api.nexotao.com/v1", apiKey: "sk-nexo-..." })
 
const resp = await client.chat.completions.create({
  model: "nova-micro",
  messages: [{ role: "user", content: "Hello" }],
})
console.log(resp.choices[0].message.content)

Every response includes an X-Cost-Rp header (the actual cost in Rupiah) and X-Request-Id. See Billing & Pricing for details.

Switch models by changing one string

Same call, cheaper or stronger — just change the model:

• claude-opus-4-6 — flagship reasoning, vision, tools, and a 1M-token context.
• qwen3-coder-next — agentic coding with a 256K-token context.
• nova-micro — the lowest-priced agentic model in the Phase 1 catalog.
• deepseek-v3-2 or gpt-oss-20b — chat-only; do not use them in clients that require tool calling.
