Two variables, two formats.
The same endpoint speaks Anthropic and OpenAI.
# Claude Code
export ANTHROPIC_BASE_URL="https://api.nexoai.dev"
export ANTHROPIC_AUTH_TOKEN="sk-nxo-••••••••••••••••"# Codex / OpenAI-compatible
export OPENAI_BASE_URL="https://api.nexoai.dev"
export OPENAI_API_KEY="sk-nxo-••••••••••••••••"03 · CLAUDE CODE
It works in your terminal.
No extra config — just launch it.
# both exports above, then:
claude04 · CODEX / OPENAI SDK
curl or Python, same key.
Anything that speaks OpenAI speaks NexoAI.
# chat completions, direct
curl https://api.nexoai.dev/v1/chat/completions \
-H "Authorization: Bearer ***" \
-H "Content-Type: application/json" \
-d '{"model": "claude-haiku-4-5",
"messages": [{"role": "user", "content": "Ship."}]}'# pip install openai — the SDK reads both env vars
from openai import OpenAI
client = OpenAI()
resp = client.chat.completions.create(
model="claude-haiku-4-5",
messages=[{"role": "user", "content": "Ship."}],
)
