Access Claude, GPT & DeepSeek from ONE API — pay-per-token, no subscription

#ai #llm #api #webdev

You don't have a "which model is best" problem. You have a seven-logins, three-credit-cards, four-invoices problem.

Every serious AI app ends up wanting more than one model. Claude for the hard reasoning. GPT for the tool-calling. DeepSeek for the cheap high-volume grunt work. So you sign up everywhere — separate keys, separate dashboards, separate monthly minimums, separate USD credit-card charges — just to answer a question you could have answered in an afternoon: which model is actually good for my use case?

That's the tax. It isn't the model price. It's everything wrapped around it.

One API, one key, one balance

Nexotao is a single OpenAI-compatible gateway that fronts every major model — Claude, GPT, DeepSeek, Grok and more — behind one key and one balance. You point your existing SDK at one base URL, drop in a Nexotao key, and switch models by changing a single string:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.nexotao.com/v1",
    api_key="YOUR_NEXOTAO_KEY",
)

# swap models by changing one string — same balance, same key
resp = client.chat.completions.create(
    model="deepseek-v4-pro",          # or claude-opus-4-8, gpt-5-mini, grok-4.3 …
    messages=[{"role": "user", "content": "Refactor this function..."}],
)

No new SDK. No per-provider migration. It also speaks the Anthropic format, so Claude Code and Anthropic SDKs point at it too.

Pay-per-token, not per-month

There is no plan and no seat. You top up a balance and every call draws it down by the exact tokens you use — input and output billed separately at each model's live rate. Nothing expires on a billing cycle. A model you tried once and abandoned costs you nothing next month.

That changes how you experiment. Want to A/B an ultra-cheap workhorse against a frontier flagship on the same prompt? Do it on one balance, in one afternoon, and pay cents for the comparison instead of standing up two paid accounts.

What does it cost?

Prices move, so I'm not going to freeze a number in a blog post. The full per-token catalog — every model, in Rupiah and USD, from an ultra-cheap workhorse up to a frontier flagship — lives here and stays current: harga API AI termurah → (full Rupiah + USD view at nexotao.com/harga).

No credit card required, either — top up with QRIS or crypto (USDT / USDC).

Try it

Create a key and top up in about a minute: dashboard.nexotao.com. Point one base URL at Nexotao and you've got Claude, GPT and DeepSeek on tap — pay-per-token, no subscription.
