What to know about accessing Nio API during the platform migration
If you’re already using Nio API (api.nio.gs), there’s one important thing to know: Nio API is migrating its admin dashboard to a new *.newapi.gs domain system.
The good news: the original API endpoint api.nio.gs/v1/ remains backward compatible — your existing code and API key don’t need to be updated right away and will keep working normally.
That said, it’s worth following the official channels to learn about the new integration method once the migration is complete, so the service doesn’t suddenly break once compatibility support ends.
Integration example
from openai import OpenAI
# Current endpoint (compatible throughout the migration)
client = OpenAI(
api_key="your Nio API key",
base_url="https://api.nio.gs/v1"
)
response = client.chat.completions.create(
model="claude-opus-4-8",
messages=[{"role": "user", "content": "Hi, help me write a Python snippet"}]
)Once the migration is complete, the endpoint may change to one under the new domain system — check Nio API’s official announcements for the latest details.
Model coverage
Nio API covers mainstream models commonly used across a range of business scenarios:
- Anthropic Claude: Opus 4.8, Sonnet 4.6, Haiku 4.5
- OpenAI GPT: GPT-5.5, GPT-4o
- Google Gemini: Gemini series
- DeepSeek: V4 Pro, V4 Flash
This broad coverage handles most text-generation and conversational use cases, and suits developers who need to switch flexibly between multiple models.
Domain migration: how to assess the risk
When a relay platform migrates its domain or infrastructure, a few signals are worth watching:
- Is there a public migration timeline? A migration with a clear timeline is more trustworthy than “switching over one day without warning”
- Is a compatibility period promised? Nio API explicitly states the original endpoint remains backward compatible — that’s a positive signal
- Is there a user-notification channel? QQ groups, Telegram groups, email notifications, and the like
Before the migration completes, it’s worth making the base_url in your project configurable rather than hardcoded — that makes switching over much simpler.
If you need a more established, longer-running track record, compare against DMXAPI (an established, stable veteran), 302.AI (full-featured), or Laozhang API (solid reputation for stability).

Pros
- Backward-compatibility commitment: while migrating to a new domain, the original endpoint api.nio.gs/v1/ remains backward compatible, so already-integrated projects don't need to update right away
- Comprehensive model coverage: mainstream text models are essentially all covered, suiting developers who need to switch between multiple models
- Mainland direct connect: no proxy required
Cons
- Domain migration in progress — the platform is in a transitional period, which adds some uncertainty to stability
- Limited public documentation and community information
- Relatively niche; a longer operating track record is needed to confirm long-term reliability
