Send one request. Routed to the best upstream. Failover in milliseconds. One bill for everything.

01 — Request

Send one request.

Keep the OpenAI SDK you already use. Point base_url at NixAPI and every model sits behind a single key.

02 — Route

Routed to the best upstream.

Each call goes to the healthiest, fastest channel for that model, measured continuously.

03 — Failover

Failover in milliseconds.

When a provider slows down or errors out, traffic moves to a healthy route before your users notice.

04 — Billing

One bill for everything.

Tokens from every provider land on a single, itemised balance. Top up once, spend on any model.

FAQ

Questions, answered.

What is NixAPI?

NixAPI is an AI API gateway. It gives you one OpenAI-compatible endpoint and one API key to call models from OpenAI, Anthropic, Google, DeepSeek, Alibaba Qwen and other providers.

Do I need to change my code?

No. Keep your existing OpenAI SDK or HTTP client, change base_url to https://api.nixapi.com/v1 and use your NixAPI key. Request and response formats stay the same.

Which models are supported?

More than 370+ models, including GPT, Claude, Gemini, DeepSeek, Qwen, Kimi, GLM and Grok families. The full, up-to-date list with prices is on the pricing page.

How is usage billed?

Pay as you go. You top up a balance and each request is charged per token at the listed model price. There is no subscription or monthly minimum.

What happens when a provider goes down?

NixAPI health-checks every upstream channel. If one slows down or returns errors, requests are automatically routed to a healthy channel for the same model.

How do I get support?

Reach the team through the contact page in the console. Technical guides and API references are in the documentation.
