OpenAI-compatible gateway

Use OpenAI models through APIXO

Keep the OpenAI SDK and request format. Change the baseURL, use your APIXO key, and choose any OpenAI model ID from the table.

Base URL

https://llm.apixo.ai/v1

API key

APIXO_API_KEY

Model ID

gpt-5.3-codex

Official upstream route

Selected model, matching upstream model.

APIXO routes each request to the corresponding upstream model, so stability, capability, and output quality stay aligned with official model behavior.

Official or compliant channels

Provider-native format

No reverse-engineered API access

No spoofing, mixing, or fallback

Official SDK quick start

The request body stays provider-native. Replace the baseURL and API key only.
